How To Choose A Fiber Transceiver

Fiber transceiver used in the Ethernet cable cann’t be overwritten, you must use the fiber to extend 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 optic transceivers, 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 compatible with the NICs, repeaters, hubs and switches and other network equipment of other manufacturers, fiber optic transceiver 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-optic transceiver products are constantly improved to better meet the access network construction needs.

 

How to choose a fiber transceiver? Due to fiber converter is one of the LAN connection device, it is necessary to consider the mutual compatibility with the surrounding environment, and product stability, reliability, and vice versa: the prices were lower, cann’t get customer all like!

 

1. Whether to support full-duplex and half duplex?

 

Some chips on the market currently only use full-duplex environment, can not support half-duplex, such as the receipt of other brands of switches or HUB and it is using half-duplex mode, will cause serious conflict and loss.

 

2. Whether and other optical transceiver done connection test?

 

An increasing number of currently available fiber optic transceivers, transceivers, such as the mutual compatibility of different brands of transceivers in advance didn’t make the test will produce loss, the transfer time is too long, suddenly fast and slow phenomena such as.

 

3. Whether there is a safety device to prevent packet loss?

 

Some vendors in the manufacture of fiber optic transceivers, transceiver, in order to reduce costs, often the data transfer mode register, this approach is the biggest drawback is instability in the transmission, packet loss, and the best is to use the buffer line. can be safe and to avoid data loss.

 

4. Temperature adaptability?

 

Fiber optic transceivers, when used, will produce high fever, high temperature (not greater than 85C), fiber optic transceiver is working properly? Is very worthy of the factors that customers consider!

 

5. Whether conforming to the IEEE802.3u standard?

 

Such as fiber optic transceivers comply with IEEE802.3 standard, that the delay time control in 46bit, it means that the transmission distance of fiber-optic transceiver will be shortened if more than 46bit!
