How to distinguish between single fiber and double fiber transceiver?

by：Fiber Hope 2020-07-15

there are two ways to distinguish between single fiber transceiver and double fiber transceiver.

(1) when the optical transceiver embedded light module, optical transceiver in accordance with the connection of the number of fiber core of fiber optic jumper divided into single fiber transceiver and double fiber transceiver. The single fiber transceiver ( Right) Connection of linear for a fiber core of fiber optic jumper, this a fiber core is responsible for transmitting data and be responsible for receiving data; The double fiber transceiver ( Left) The connected linear for two fiber core of fiber optic jumper, one of the fiber core is responsible for data transmission, another fiber core is responsible for receiving data.

(2) when there is no built-in light optical transceiver module, need according to the inserted optical module is to distinguish between single fiber transceiver or double fiber transceiver. When inserted in the optical transceiver is single fiber bi-directional optical module, interface of simplex types, this optical transceiver for single fiber transceiver ( Right) ; When inserted in the optical transceiver is double fiber bidirectional optical module, interface for duplex type, this transceiver for double fiber transceiver ( Left) 。

There are a wide variety of which are scientifically tested to have positive effects on the ability to fibre optic cable transmission speed. fibre optic cable transmission speed fiber optic cable is one of them.
