Specifications:

GPON OLT SFP optical module is specially designed for Gigabit Passive Optical Network (GPON) 20 km transmission. The module contains a 1490nm continuous mode transmitter and a 1310nm burst mode receiver. The transmitter uses a 1490nm DFB laser and an integrated laser driver. The laser driver includes APC and temperature compensation functions to keep the emitted light power and extinction ratio constant during temperature and aging processes.

The receiver uses an integrated APD photodetector and BM preamplifier mounted together. The receiver has a wide dynamic range: 29~41dB and a fast response rate. When the rising edge of the trigger signal is detected, the built-in DDM processor quickly converts the burst optical power to obtain a digital signal output. Metal encapsulation ensures excellent EMI and EMC characteristics.
