In the telecommunications industry today, how to install the fiber optics that each optical engineer must learn in their work. Don't froget, when you install the fiber optics, you have to testing your fiber optic system. Optical-fiber tests are one of the final and many important procedures in installing optical networks.

How to set up the fiber optic cable?

Fiber optic cable may be installed indoors or outdoors using several different installation processes. Outdoor cable might be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles. Indoor cables could be installed in raceways, cable trays,put into hangers, pulled into conduit or innerduct or blown though special ducts with compressed gas. Cellular phone process will depend on the nature of the installation and also the kind of cable being used. Installation methods for both wire and optical fiber communications cables are similar. Fiber cable is designed to be pulled with much greater force than copper wire if pulled correctly, but excess stress may harm the fibers, potentially causing eventual failure.

The install fiber optic cable tips:

a) Stick to the cable manufacturer's recommendations. Fiber optic cable is often custom-designed for that installation and the manufacturer might have specific instructions on its installation.

b) Check the cable length to make sure the cable being pulled is long enough for that go to prevent needing to splice fiber and provide special protection for the splices.

c) Attempt to complete the installation in a single pull. Just before any installation, assess the route carefully to look for the ways of installation and obstacles likely to be encountered.

Testing fiber optic cables steps:

After installation, test each fiber in most fiber optic cables for verification of proper installation. Carry out the following tests:

a) Continuity testing to find out that the fiber routing and/or polarization is correct and documentation is proper.

b) End-to-end insertion loss utilizing an OLTS power meter and source. Test multimode cables by using TIA/EIA 526-14 Method B, and single-mode cables using TIA/EIA 526-7 (single-mode). Total loss shall be under the calculated maximum loss for the cable based on appropriate standards or customer specifications.

c) Optional OTDR testing may be used to verify cable installation and splice performance. However, OTDR testing shall not be accustomed to determine cable loss.

d) If the design documentation does not include cable plant length, which is not recorded during installation, test the length of the fiber using the length feature on an OTDR, or some OLTSs.

e) If testing shows variances from expected losses troubleshoot the issues and proper them.

Communication industry continues to be stormed through the creation of fiber optic cable. The main advantages provided by these cables incorporate a wider bandwidth, light weight, small size and in nevertheless has more flexibility. In addition to it, the main cause of its popularity is that advanced technology used by these cables. As you may know the fiber optic cable, the fiber optic cable is really a cable containing a number of optical fibers. The optical fiber elements are typically individually coated with plastic layers and found in a protective tube ideal for environmental surroundings in which the cable will be deployed. For example, the 10g fiber cable is has plastic layers and found in a protective tube, we can provide different jacket color and then any length are for sale to these cables .

Actually, the entire fiber optic technology utilizes fiber optics. The normal fibers today are created from glass or plastic since it is possible to make them thin and long. Also both glass and plastic are transparent at particular wavelengths, which permit the fiber to steer light efficiently. These optical fibers are thin, ultra-flexible and transparent and transmit the sunshine between two ends from the fiber quality as compared to copper wire. So, using their superior technology they are more appropriate for smooth communication between far distances. Along with it, using these cables results in much less loss of signals meaning uninterrupted and smooth communication. Greater than 80% of the distance data traffic with the intelligent utilization of these fiber optic technology is transferred.

Other advantages of fiber optic cables include it is inexpensive and suits properly to extremely thin diameters within the range between 0.8mm to 40mm. Is going to be extremely thin, numerous fibers run together along many connections in the same cable. It provides a clearer telephone lines and TV reception, as the light signals which are within the same cable doesn't hinder each other to function. This ultimately results in less loss of signal. These cables may also be called as the safer ones because no electricity passes through these cables and therefore there'll not be any fire issues.

In comparison with other lines for example copper wires, these cables are the superior ones because they are lightweight and small sized. With the above advantages, it is obvious why fiber optic cables which are utilized in many telecommunications and computer networks. These cables are the most trustworthy and finest replacing copper cables.

Small Form factor Plug (SFP) is a compact transceiver that is popular in telecommunication and for data communication. It uses a device which contains a parent board and interfaces it to a fiber optic networking cable. SFP is mainly made to hold Gigabit Ethernet and various other standard communications in it.

Wide types of SFPs can be found, providing the customer by having an option to choose among various unique models, which suits the apt needs. They will use different set of transmitter types on it facilitating you to find the desired transceiver. The SFP transceiver gives link for getting the necessary optical reach through the existing optical fiber. For instance you will find optical fibers like single mode fiber and multimode fiber separately for appropriate usage. In every mode there are different group of fibers flexible for the users' choice.

In general the rate of signal transmission of SFP module ranges from 100Mbps to 4Gbps. The transceivers work on a distance range varying from 500 meters to 100 kilo meters and also the working wavelength for a number of modules are generally 850nm, 1310nm or sometimes 1550nm. This excellent type of transceiver allows an ease to alter and keep in comparison with other traditional modules. The users can certainly and genuinely replace single module of SFP while the process is running rather than replacing the whole board containing large number of modules in it.


SFP transceivers find the position in commercial market having a capacity to vary data rates as much as 4.25 Gigabits in a single second. The upgraded version namely SFP plus or SFP+ supports data rate as high as 10 Gigabits per second. This rate of transfer is Ten times faster than usual Gigabit Ethernet device. The characteristics of 10G SFP are multifold as following:

It can be used instantly connecting to internet.
It can be hotly plugged and employed for transferring data.
It may withstand temperature up to 70 degree Celsius and may even function at zero degrees Celsius.

Some people might think that SFP would consume more current. Actually, it's not true. SFP consumes less power but is highly efficient in transferring data. In recent times, SFP transceiver can be used for supporting digital diagnostics monitoring (DDM) activities as reported by the standard matching to it. Hence it is employed for digital optical monitoring services. By making use of this element, the user will keep track of the real time limiting factor of the SFP and monitor the optical input power and output power along with temperature and also the voltage way to obtain the transceiver.

There are lots of benefits of using SFP. You could have multiple choices for internet connectivity using this swappable input/output appliance. The device of SFP comes with copper wire interface by which the user can conveniently hold optical fiber communications. It's now possible to transfer SDI video outputs over the coaxial cable through the 10G SFP copper. There is also CWDM/DWDM support in some single mode fiber transceivers.

Nowadays SFP has numerous commercial applications in SONET network, point to point mode of networking, Gigabit Ethernet, metro access networks, FTTD, routers, switches, bridges, servers, etc. It also finds a lot of demand kept in storage area network, local area network, high-speed computer links and switching system. SFP offers large range of detachable interfaces to UTP or coaxial cables and multimode or single-mode fibers.

Finisar Corporation (NASDAQ: FNSR [FREE Stock Trend Analysis]), a global technology leader for subsystems and components for fiber optic communications, today announced financial results for its fourth quarter and fiscal year ended April 28, 2013.


"I am pleased to report fiscal fourth quarter revenues of $243.4 million, which is $5.1 million, or 2.1%, greater than the prior quarter. Our growth in revenues came primarily from sales of 10G and 100G Ethernet transceivers and transponders for datacom applications. Our favorable product mix in the quarter enabled us to achieve gross margin and earnings per diluted share that exceeded our guidance range," said Jerry Rawls, Finisar's executive Chairman of the Board.

"During the quarter, we continued to invest significantly in technology and product development and made substantial progress on a number of new products for our datacom and telecom products lines, including our next generation 100G CFP transceiver, 12x25G optical engine and new generation dual wavelength selective switch product family," said Eitan Gertel, Finisar's Chief Executive Officer.

Financial Statement Highlights for the Fourth Quarter of Fiscal 2013:

Revenues increased to $243.4 million, up $5.1 million, or 2.1%, from $238.4 million in the preceding quarter as continued strength in sales of datacom products was partially offset by lower telecom product revenue primarily as the result of sluggish carrier capital expenditure levels and a full three month impact of annual price reductions for telecom products most of which, as in prior years, went into effect in January.

Compared to the preceding quarter, the sale of products for datacom applications increased by $16.3 million, or 11.0%, and the sale of products for telecom applications decreased by $11.2 million, or (12.3)%.

Gross margin decreased to 27.7% on a GAAP basis from 28.5% in the preceding quarter, primarily as the result of a charge for impairment of certain purchased intangibles related to acquired developed technology and other long-lived assets.

Non-GAAP gross margin increased to 32.2% from 30.7% in the preceding quarter, primarily as the result of favorable product mix.

GAAP operating income increased $1.2 million to $0.4 million, or 0.2% of revenues, compared to $(0.8) million, or (0.3) % of revenues in the preceding quarter, primarily as the result of a gain on the fair value remeasurement of contingent consideration liability.

Non-GAAP operating income increased $2.7 million to $20.0 million, or 8.2% of revenues, compared to $17.4 million, or 7.3% of revenues, in the preceding quarter, primarily as the result of higher non-GAAP gross margins.

Cash and cash equivalents totaled $289.1 million at the end of the fourth quarter, compared to $265.5 million at the end of the preceding quarter.

Financial Statement Highlights for fiscal year 2013:

Revenues decreased to $934.3 million, down $18.2 million, or (1.9)%, from $952.6 million in the preceding year.

Compared to the preceding year, the sale of products for datacom applications increased by $53.6 million, or 10.0%, primarily from sales of 10G transponders and 100G transceivers and and the sale of products for telecom applications decreased by $71.8 million, or (17.3)%, primarily as the result of sluggish carrier capital expenditure levels.

Gross margin decreased to 27.5% on a GAAP basis and 30.9% on a non-GAAP basis from 28.7% and 31.9%, respectively, in the preceding year, primarily as the result of a decline in average selling prices.

Non-GAAP operating income decreased $24.1 million to $65.2 million, or 7.0% of revenues, from $89.3 million, or 9.4% of revenues, primarily as the result of lower gross margin and an increase in operating expenses, due to increases in employee related expenses, costs of materials associated with new product development, and the consolidation of financial results of Red-C Optical Networks, which was acquired in fiscal 2013.

GAAP operating income (loss) decreased $49.7 million to $(5.6) million, or (0.6)% of revenues, from $44.2 million or 4.6% of revenues primarily as the result of the factors affecting Non-GAAP operating income and in addition the impairment of acquired developed technology and other long-lived assets.

Outlook for the First Quarter of fiscal 2014
Finisar Corporation currently expects revenues for the first quarter of fiscal 2014 to be in the range of $245 to $260 million; GAAP operating margin to in the range of approximately 5.0% to 6.5%; non-GAAP operating margin to be in the range of approximately 9.0% to 10.5% and non-GAAP earnings per diluted share to be in the range of approximately $0.22 to $0.26. The Company also noted that during the fourth fiscal quarter of 2013 and during the first week of the first quarter of fiscal 2014, the Company completed the divestment of two non-strategic subsidiaries of Ignis AS, which was acquired by Finisar in May 2012. These divested businesses accounted for approximately $5 million in revenues during the fourth quarter of fiscal 2013.

You aren't by yourself if you have difficulty keeping up with today's development in networks. There appears to be considered a lot of ruckus over things to get, when you should have it and why. Allow me to assist you to.

The greatest method to transmit data nowadays is with light-based fiber optics instead of the ancient form of electronic signals and the two greatest modules with this would be the SFP and XFP modules, which are a symbol of small form factor placable with X standing for 10 gigabyte. These modules were formed to bring you greater quality from your signal. Additionally, it's an economical method of providing changeable gigabyte ethernet fiber optic interfaces to switches and hubs that are equipped with a stock SFP slot.

Finding a trusted retailer, and fully knowing optical transceiver modules is going to be helpful when it comes time to create you buy the car. You will have networking questions and concerns. Therefore finding an experienced fiber networking vendor will be crucial. You will have to have the data possible to make a good choice when choosing manufacturers as well as their modules.

Superior optical fibers transport waves of information sent by optical transceiver modules. Modules transport and receive optical signals. Underneath the Multi-Source Agreement, these form factors are made by companies. Specific standards must be met in their building. Transfer speeds are what exactly are accustomed to classify optical transceivers together. Each supports rates from 1Gbps to 10Gbps. Module factors are referred to as SFP and GBIC are 1Gbps. These form factors support transmissions larger than 4Gbps right down to 100mbps. Modules are known as XENPAK, XFP, X2 and SFP support speeds of up to 10Gbps transportation.

10G XENPAK modules are the widest in 10G transceiver interfaces and can include a dual SC fiber interface. Cisco SFP modules can be found in multi-mode and single-mode optical fiber wire, as well as operating in copper wire. 15 meters may be the normal transmission length of a copper module. 300 meters be the transmission reach of multimode lines.

10G XFP transceivers are equipped for 10G network applications, including 10G Ethernet. The conventional for developing these was made by some of the leading manufacturers in the field. Straightforward to care for and change. They're also small hot plug-hole. This module is utilized in conjunction with laser multimode fibers.

Optical networking solutions are definitely an industry that is constantly on the expand and grow. Their email list above is only a sum of the optical options that you may have to choose from. Once again, choosing the best distributor will be just like crucial as your education of optical transceivers, and how they work. A vendor who sells a broad selection of optical interfaces is going to be helpful. It's critical they at least have a background experience in all kinds of fiber optical products. This is really crucial if you're not an expert yourself.

Before you start to play with your new gadget you could try to buy a fiber optic tester to ensure all is in working order and that nothing has been all messed up because of debris or oil. A 20km distance tests are most popular, but try a patch cord if you're in a bind. Lucent connectors or LC connectors are the resulting fiber ports to connect to the optical modules. Remember, look at and clean the fiber connector prior to plugging in; they cannot work if blocked with even a small piece of debris.

Because the improvement of network, it will be vital that you maintain both configuration flexibility and port utilization for equipment deployed in the intersection of legacy copper and newly installed optical networks. Copper SFP (small form factor pluggable) module ensures the SFP form factor have emerged because the best way to optimize port-level flexibility. The maturation of Copper SFP module is playing a vital role in enabling system designers to satisfy these objectives while simplifying their inventory and reducing operating costs.

Copper SFP module utilizes a copper line for linking. The copper transceiver includes transmit and receive two decision points, Radiating portion includes laser circuit and optical maser, Receiving part includes PIN, TIA and Limtiting Amp, completing digital signal transparent O/E, the E/O conversion functions. Typical copper SFP things like Cisco GLC T and SFP GE T, these SFP modules are used in Gigabit networks and they're fully suitable for 1000Base-T. SFP GE T may be the copper SFP which are with extended working temperature and DOM support. And i'll talk about the common widely used 1000BASE-T copper SFP module below.

1000BASE-T 1000Base T SFP module means the little form fiber optic transceiver that complies with 1000Base-T standards. 1000Base T SFP is copper SFP transceivers also it uses category 5 cables for linking and with a really limited working span. 1000Base T SFP is perfect for Gigabit Ethernet and delay pills work under IEEE 802.3 standards.

How Many Kinds Of SFP Transceivers Do You Know? Yes, I know. From the FiberStore, I find this answer.The Fiber Optic Transceivers have a full range of sfp modules.Fiberstore supply various kinds of SFP module 100% compatible with Cisco SFP, HP SFP, Juniper SFP, Netgear SFP, DELL SFP, CWDM SFP, DWDM SFP, BIDI SFP, 10G SFP and so on.So many types of SFP transceiver , I will detail several types sfp tansceiver modules.

First Types,CWDM SFP:

The CWDM SFP (small form-factor pluggable) transceiver is really a compact optical transceiver utilized in optical communications both for telecommunication and knowledge communications applications about the wavelength. CWDM SFP are employed to link the ports towards the fiber optic network, typical CWDM SFP like Cisco's could support both Gigabit Ethernet and Fiber Channel. CWDM SFP transceiver modules utilize the SFP interface for connecting the gear and use dual LC PC fiber connector interface allowing you to connect the optical network. FiberStore CWDM SFP transceivers can be found using a variety of different transmitter and receiver types, allowing users to select the right transceiver for every connect to provide the required optical reach over the available optical fiber.

Second Types,DWDM SFP:

The Dense Wavelength-Division Multiplexing (DWDM) transceivers offer DWDM transport with dramatically lower power and cost in the standard pluggable SFP package. Fiberstore DWDM SFP comes in all 100 GHz C/L-band wavelengths around the DWDM ITU grid. As multirate interfaces they support any protocol from 100 Mbps to 4.25 Gbps. The modules are eligible of the IEEE802.3 Gigabit Ethernet standard and ANSI Fiber Channel specifications, they may be ideal for interconnections in Gigabit Ethernet and Fiber Channel environments. The DWDM SFP is designed to accept DWDM SONET/SDH (without or with FEC) for 200km links and Ethernet/Fiber Channel protocol traffic for 80km links.

Third Types,10G SFP:

The 10G SFP Transceiver Modules refers to 10G SFP Plus Transceivers,someone know that the sfp is an enhanced version of the SFP that supports data rates as much as 10 Gbit/s. Several standards for 10G SFP has been released, 10GBase-SR is perfect for OM3 multimode optical fiber, relevant SFP plus working distance 300 meters max, 10GBase-LR is for single mode optical fiber, relevant SFP plus working distance 10km, 10GBase-LRM is made for FDDI multimode fiber, the SFP plus working distance 220 meters.
