The GEP-1143-20 transceiver module is designed for Gigabit Ethernet Passive Optical Network (EPON) 20km transmission.
The transmitter section uses a 1310nm FP laser and an integrated BM laser driver which is designed to perform very small burst enable/disable delay time. The laser driver also includes digital APC and temperature compensation circuit, which are used for keeping the launch optical power and extinction ratio constant over temperature and aging.
The receiver section uses an integrated 1490nm InGaAs Pin photodiode and preamplifier mounted together. It has the function that indicates receiver signal-detected status (active high).
An integrated WDM coupler can separate 1490nm input light and 1310nm output light.
