If you have a network that uses the older type of copper cables and another network that utilizes faster and more reliable fiber optic cables, it is possible to connect them together by using a special product named Fiber Media Converter. A media converter changes signals on a copper cable to signals that run on fiber, make one cable Ą°lookĄ± like another cable without changing the nature of the network. Due to this function, network executives who need to upgrade their systems from copper to fiber but donĄŻt have the budget, manpower or time, just turn to media converters.

Fiber Optic Media Converter is a small device with two media-dependent interfaces and a power supply, simply receive data signals from one media, convert and transmit them to another media. It can be installed almost anywhere in a network. The style of connector depends on the selection of media to be converted by the unit. In a Fast Ethernet environment, a 100Base-TX to 100Base-FX Media Converter connects a 100Base-TX twisted-pair device to a 100Base-FX compliant single or multimode fiber port that has a fiber-optic connector. In a Gigabit Ethernet, a media converter commonly is deployed to convert multimode to single-mode fiber. Media converters are designed to be implemented in Ethernet networks and some ATM applications. Media converters are also playing a role in facilitating the optical last-mile connection to metropolitan-area networks.

How does a fiber optic media converter work?

Media converters work on the physical layer of the network. They receive data signals from one media and convert them to another while remaining invisible to data traffic and other net devices. They do not interfere with upper-level protocol information. This lets them support quality of service and Layer 3 switching.

Media converters change the format of an Ethernet-based signal on Cat-5 into a format compatible with fiber optics. At the other end of the fiber cable run, a second media converter is used to change the data back to its original format. One important difference to note between Cat-5 and fiber is that Cat-5 cables and RJ45 jacks are bidirectional while fiber is not. Thus, every fiber run in a system must include two fiber cables, one carrying data in each direction. These are typically labeled transmit (or Tx) and receive (or Rx).

Media Converters can function in either half-duplex or full duplex mode. Full duplex Ethernet over UTP runs at 20 or 200Mbps, while half-duplex Ethernet over UTP runs at either 10 or 100 Mbps. Full duplex Ethernet is especially valuable in linking two switches or connecting a switch to a file server. No adjustments are necessary when using either mode. A Fiber Optic Media Converter will automatically sense which mode is in operation.

There are several types of fiber optic media converters available, such as Ethernet Media Converter, 10/100/1000 Media Converters, Gigabit Ethernet Converter, Mulitmode Singlemode Media Converter, 10 Gigabit Ethernet Converter, Media Converter Rack Chassis, etc.

Fiber optic converter should be placed in a secure location that can not be disturbed by people or machinery. Every computer connected to the fiber optic cable will lose itĄŻs internet connection if the converter is removed or broken. Converters contain special materials that only work properly in specific temperature ranges so it is important to keep them in controlled temperature rooms that never get too hot or cold.

PDH Multiplexer, or Plesiochronous Digital Hierarchy multiplexer, is a kind of point-to-point optical transmission equipment used to transport large quantities of data over digital transport media, for example fiber-optic and microwave radio systems. PDH Multiplexer is designed of highly integrated structure and provides 16 standard E1 interfaces together with one channel of order wire, with self-contained alarm and NM functions, in addition to self-testing and E1 loop-back testing functions. The unit is popularly with telecommunication operator. It is suitable running a business for communication operator, government and kinds of entities.

PDH was created in the early 1960s. It derives its names in the Greek term "plesio," meaning near, and "chronos," meaning time. The name refers back to the fact that networks using PDH run in a state of just about, although not quite, perfect synchronization. PDH was the very first standardized multiplexing hierarchy based on time-division multiplexing. It works by channeling numerous individual channels into higher-level channels.

Work Theory Of PDH Multiplexer
The PDH product is in line with the theory when you've two identical clocks, each the same brand, style and everything, there is no guarantee that they'll run at the exact same speed. Most likely one of these is going to be slightly out of synchronization using the other. The transmitting multiplexer combines the incoming data streams, compensates for just about any slower incoming information, reconstructs the initial data and sends it back out at the correct rates. This system allows for that slight variation in speed and corrects it during transfer to keep the machine constantly running without pausing and waiting for certain slower data to arrive before sending it on. PDH simply fills within the missing bits to match a smooth change in data.

PDH made little provision for management of the network, and the need to fully de-multiplex a high level carrier to extract a lower level signal resulted in enhancing the capacity of PDH networks beyond a certain point wasn't economically viable. The main economic factor was the cost of the equipment required at each cross-connect point within the network where either individual channels or low-level multiplexed data streams should be extracted or added. Additionally, it added additional latency and increased the possibility of errors occurring, thereby reducing network reliability.

Available Kinds of PDH multiplexer
Traditionally, each channel in PDH was a digitized voice, but video information and knowledge can also be sent of these channels. The fundamental channel is 64 Kbits per second, which is the bandwidth that is required to deliver a voice call that's been converted from analog to digital.

N*E1 PDH Fiber Optic Multiplexers make use of the PDH fiber transmission technologies. The 2M (E1) interfaces can interact with the exchanger, light loop tool and multi-diplexer directly to form the micromini or the special network. Complete alarm function for N*E1 PDH Fiber Optic Multiplexers, it's stable, easy to maintenance and install, small in size. It can support one digital service telephone.

PDH Multiplexer can multiplex 4/8/16E1, Ethernet Media Converter (2*10/100Mbps) and V.35 signals in one fiber channel to deliver. It's ideal for low capacity, point-to-point application of remote transmission. The PDH Multiplexer can be applied to create economical and flexible multi-service transmission networks, employed for relay between switch offices, data transmission of LAN, 2M access of lease service for key clients, voice cutover for residental areas/intelligent buildings, and connection of base stations and other various digital transmission networks. Fiber Optic Multiplexer is reliable, stable, simple to install and keep, which may be monitored from Fi-view-MST management software, that is popular in voice and knowledge application field.

A fiber optic media converter uses optical fiber because the media, receives data signals, sent via one media, convert the signals after which transmit the signals into a different type of media. It is primarily used in connecting older copper-based cabling systems, for example twisted pair, to the faster fiber-optic networks. The converters are generally used in the large metropolitan area networks (MANs), as well as large business networks, referred to as enterprise networks nowadays.

Fiber Media Converter supports a number of communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, in addition to multiple cabling types such as twisted pair, multi-mode and single-mode fiber optics. On some devices, Simple Network Management Protocol (SNMP) enables proactive management of link status, monitoring chassis environmental statistics and sending traps to network managers in case of a fiber break or perhaps link loss on the copper port.

Media converter types vary from small standalone devices and PC card converters to high port-density chassis systems that offer many advanced features for network management.

Ethernet Media Converter

Typical type like Ethernet Media Converter, these converters usually are utilized in Ethernet for connecting Ethernet link, which usually use UTP cables to optical fiber signal, which is transmitted via optical fiber cables. An Ethernet to Fiber Media Converter can also be used where there is higher level of electromagnetic interference or EMI which is a common phenomenon present in industrial plants. This interference can cause corruption of information over copper-based Ethernet links. Data transmitted over fiber optic cable however is completely immune to this kind of noise. An Ethernet to Fiber Optic Converter therefore allows you to inter-connect your copper-ethernet devices over fiber ensuring optimal data transmission over the plant floor.

The most common type fiber to ethernet media converter is one that's a standalone device with its own power adapter. They convert fixed speed Fast Ethernet, Gigabit or rate converting 10/100/1000 UTP links to 100Base-FX or 1000Base-X fiber connections. In which a large density of media converters are required, chassis-based systems can also be found. These rack mountable units can house up to 19 managed or unmanaged media converter modules providing redundant power for AC and 48v DC environments.

10/100/100M Gigabit Ethernet Media Converter

The 10/100/100M Gigabit Ethernet Media Converter series is designed to satisfy the massive needs for network deployment capable to extend a copper based Fast network via fiber cable to some maximum distance as much as 100KM.

Single Mode To Multimode Fiber Converter

The single mode to multimode converter is straightforward and reliable device allowing you to connect multimode fiber traffic to single mode fiber devices and links. Begin using these bi-directional fiber media converters individually to connect multimode and single mode devices, or perhaps in pairs at each end of long-distance single mode fiber links. These converters support multimode signal transmitted by 850nm and 1310nm and single mode signal with 1310nm and 1550nm, it is widely used in LANs, WANs and fiber optic data communications.

Media Converter Chassis

Media Converter Chassis is principally used to manage the different media converters, all the converters connected to the chassis will share same power, so that they are simple to manage. Typical fiber optic converter chassis are with 14 slots or 16 slots. Normally the 14 slot fiber optic chassis is perfect for stand-alone type converter, 16 slot fiber optic converter chassis is for card type converters. All the converters installed on the chassis will share one power supply and therefore you can easily manage. Typically, power supply of the chassis can be 220V or -48V optional. Chassis type fiber optic converters are plug and play, they use the traditional UTP cable to link the Ethernet ports and usually with FC or SC fiber optic interface. Typical type is a 19-inch size rack-mounted fiber converter chassis.

Fiber Media Converter is an easy network equipment, supporting a variety of data communication protocols, including Ethernet, Fast Ethernet, Gigabit Ethernet, Serial Datacom interfaces, E1 or T1 voice/data communications and multiple wiring types, including coaxial cable, twisted pair, single mode and multimode optical fiber. Media conversion types range from small independent equipment and PC card converter, high-end mouth density chassis provides many advanced features, network management system.

Fiber media converters are key aspects of optical networking because its long distance operation, high bandwidth capacity and reliability make fiber optics essentially the most desired channel for data communications. Rather than costly, across-the-board upgrades, media converters can extend the productive time of the previous cabling plus the active equipment.FiberStore offer a huge selection of fiber media converters such as Ethernet Media Converter, 10/100/1000 media converters, Gigabit Ethernet converters, multimode singlemode media converter and media converter rack chassis for sale at good prices and worldwide delivery,the Ethernet Media Converter is considered the most everyday sort of fiber optic media converter,to go to Fiberstore.com to pick your Fiber Media Converters now.Buy with confidence.

Ethernet Media Converter can connect with various optical fiber cable such as multimode, single mode or single strand fiber cable. Options are available for many distances to accommodate the demands of a unique ethernet to fiber application. And, fiber interface connectors can be dual ST, dual SC, dual LC or single SC type.

The reason to use media converters at all? This does not have a technical answer even so the answer is more commercial - media converters will not require fiber enabled switches (they can be used despite unmanaged basic switches) and as such the connectivity option is cost-effective. For the single fiber link, changing the whole switches and purchasing fiber modules at either end can be quite a more costly proposition. But direct termination of fiber links on network switches can also be strongly suggested.

In addition to that, the media converter provides more choices, you can buy an individual couple of media converter (stand alone devices) at either end or have a Media Converter Chassis based system, to insert multiple media converters from 1 to 18/19 in single increments, they are also support hot swappable, switch with redundant power supplies and automobiles consolidation.But network switches consist of more rigid configurations - 2, 4, 24 or 48 ports only. If you'd like 5 fiber connections, for example, you may want to buy two network switches with 4 fiber ports each and 24/48 copper ports each whether you're going to utilize the remaining fiber and copper ports! And yeah, a few of the network switches would not have fiber interfaces whatsoever.
