OPTICAL LINE TERMINAL MODULE AND UPLINK TRANSMISSION MODULE

摘要

An Optical Line Terminal (OLT) module and an Uplink Transmission (UT) module are used to solve the problem that, in the art, a mass of preambles are needed to ensure the performance when the OLT module performs uplink transmitting, thus increasing the cost and reducing the efficiency. The OLT module includes: a 10G Receiver Optical Sub-Assembly (ROSA), which is used for converting the received optical signals into electric signals, and outputting the electric signals to a 10G Burst Mode Limiting Amplifier (BMLIA) through a conditioning module; the 10G BMLIA, which is used for amplifying and outputting electric signals; and a conditioning module, which is used for adjusting the sensitivity of the 10G BMLIA and receiving setting time. Since the sensitivity of 10G BMLIA and the receiving setting time are adjusted by the conditioning module, on the premise of ensuring the performance, the number of preambles is reduced, thereby reducing the cost and improving the efficiency.
