Fiber media converter classification

Information construction by leaps and bounds, The growing demand for data, voice, image and multimedia communications, and Ethernet broadband access is mentioned more and more important position. Traditional Cat5 cable can only make Ethernet signal transmission 100 meters transmission distance and coverage can not meet the needs of the actual network environment. At the same time, the fiber optic communications with its advantages of large capacity of information, confidentiality, light weight, small size, relay, long distance transmission has been widely used. Fiber media converter use of this high-speed fiber optic transmission media a good solution to the problem of Ethernet transmission. Direct use in some of the larger enterprises, network construction, fiber optic backbone network established for the transmission medium, the internal LAN transmission medium is generally copper wire, how to achieve local area network with fiber optic backbone connected. This requires a different port, different linear conversion between different fiber and to ensure that the link quality.

The emergence of Fiber media converter to make twisted pair electrical signals and optical signals conversion,ensure the smooth transmission of data packets between two networks, it network transmission distance limit extended to 100 km from the copper wire 100 meters (single multimode fiber).  In information technology infrastructure of Fiber media converter, usually pay more attention to routers, switches, and even the network card for the node data exchange network equipment, but often overlooked media conversion such non-essential to the core of the network equipment. Especially when some of the information required in a high degree of government institutions and enterprises in the data traffic, network construction need to directly connect to the backbone network of fiber optic transmission medium, the internal LAN transmission medium typically copper wire, to ensure that packet media conversion equipment in the smooth transfer between different networks become a necessity.

Fiber media converter used in the Ethernet cable can not be overwritten, you must use the fiber to extend the transmission  distance of the actual network environment, help fiber last-km line to connect to the metro and the outer layer of the network playa huge role. With Fiber media converters, also need to upgrade from copper to fiber optic, but lack of funds, manpower or time the user provides an inexpensive program. In order to ensure fully compatibel with the NICs, repeaters, hubs and switches and other network equipment of other manufacturers, Fiber media converter products must strictly comply with 10Base-T, 100Base-TX, 100Base-FX, IEEE802.3 and IEEE802.3u Ethernet standard. In addition, EMC anti-electromagnetic radiation shall comply with FCC Part15. Nowadays, the major domestic carriers are great efforts to build the residential network, campus and enterprise networks, so the amount of Fiber media converter products are constantly improved to better meet the access network construction needs.

With the development of fiber media converter, there are different Classification for fiber media converter.

Divided by the optical fiber can be divided into multi-mode fiber media converter and single mode fiber media converter.

The media convertercan transmit distance is not the same, due to the use of fiber, multimode transceiver transmission distance of 2 km to 5 km, while the single-mode media converter coverage from 20 km to 120 km. Should be noted that due to the different transmission distance, fiber media converter transmit power, receiver sensitivity and the use of wavelength will be different.
Such as the 5 km fiber-media converter transmit power is generally -20 ~-14db between the receiver sensitivity of-30db, use 1310nm wavelength; 120 km of fiber media converter transmit power and more between -5 ~ 0dB, the receiver sensitivity -38dB, the wavelength of 1550nm.

Divided by Working level / rate points can be divided into single-10M, 100M fiber media converter, 10/100M adaptive fiber media converter and 1000M fiber media converter.

Single 10M and 100M fiber media converter products at the physical layer, this layer media converterr products by bit to forward data. The forward mode with fast forwarding, transparent high latency advantages of low, suitable for the rate is fixed the link, while such devices without a consultation process before the normal communication, and therefore compatible and stability to do better.

Ethernet media converter:

Plug and Play hardware DIP switch to set the electrical port mode
Managed Ethernet media converter: support carrier-grade network management

According to the number of fibers

Can be divided into single fiber and fiber media converter, and dual-fiber media converter. As the name implies, the single-fiber devices can save half of the fiber, to receive and send data in an optical fiber, the fiber tension is very applicable. These products using the WDM technology, the use of wavelength, multi-1310nm and 1550nm. With the growing number of single fiber optical transceiver use, the product is mature and stable.
