EPON Olt SFP PX20+
Linkopto EPON OLT Transceiver module is designed for Gigabit
Ethernet Passive Optical Network(EPON)20km transmission. The module
incorporates 1490nm continuous-mode transmitter and 1310nm
burst-mode receiver.
The transmitter section uses a 1490nm DFB laser and a integrated
laser driver which is designed to be class1 eye safe under any
single fault. The laser driver includes 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 APD and BM-preamplifier mounted
together. The burst-mode receiver is resetless and wide dynamic
range over 20dB can be obtained under whole operating conditions.
The module has the function that indicates receiver signal-detected
status (active high).
An integrated WDM coupler can separate 1490nm output light and
1310nm input light.
