The GPON OLT Transceiver module is designed for Gigabit Ethernet Passive Optical Network (GPON) transmissions over a 20km distance. It incorporates a 1490nm continuous-mode transmitter and a 1310nm burst-mode receiver. The transmitter uses a 1490nm DFB laser and an integrated laser driver that ensures class-1 eye safety, even in the presence of a single fault. The laser driver includes APC and temperature compensation functions to maintain consistent launch optical power and extinction ratio in varying temperature and aging conditions.
The receiver section features an integrated APD and BM-preamplifier. The module provides a receiver burst-power-detect signal and a digitalized burst mode optical power monitoring function. The digital conversion of received ONU optical power is achieved through a Trigger input, activated by a rising edge. The DDM processor initiates a burst optical power conversion, and the digital result is accessible via the DDM interface after a specified Burst Optical Power Conversion Time. The module also incorporates an integrated WDM coupler to differentiate between 1310nm input light and 1490nm output light. Housed in a metallic package, the module guarantees excellent EMI and EMC characteristics, ensuring reliable performance in various environments.
