Gigabit light module is different from other light modules.huawei compatible sfp module Processing

Everyone knows that most of the optical modules are now carried out transmission data based on the two optical fiber lines. One optical fiber line is used to read data from computer devices, and the other is used to transmit data to the computer device. However, there is a light module that can complete the transmission data with only one fiber line. This type of optical module is a gigabit light module.

1. Basic knowledge of Gigabit Light Module

BIDI (Bidirectional) single fiber dual light module is different from the light module of the two -terminal number (TX sending end and RX receiving terminal). It only has 1 optical fiber line port number. The core light wave length of the angle difference, and then the dual transmission signal light of the real fiber line is not bright.

2. The principle of the Gigabit Light Module

The Gigabit Light Module is equipped with a wave -documented (WDM) optical fiber coupler, which is also called a dual instrument. At the same time, the 1310Nm light signal light is not bright and the 1550nm light signal light is not accepted, or in turn. Therefore, in order to better operate and reasonably operate, the Gigabit light module must be applied to the applied light wavelength according to the automatic adjustment dual -instrument with the anticipation of the signal transmitter and the signal receiver. And in line. For example, if the matching Gigabit light module and machine equipment A (up) and machine equipment B (decline) are carried out, then: the dual -work tool of the light module A must have a 1550nm acceptance of light wavelength and a 1310Nm sending light. wavelength. The dual -tooling device of the Light Module B must have a 1310Nm receiving light wavelength and a 1550nm sending light wave length.
