Applications
Gigabit Ethernet Passive Optical Network (GEPON) OLT
This is a high performance transceiver module for single fiber communications. It is designed to meet IEEE 802.3ah
requirements for optical line terminal (OLT) applications.
The 1490nm DFB LD transmitter has automatic power control (APC) function and temperature compensation circuitry to
ensure stable optical power and extinction ratio over all operating temperature range. The transmitter meets Class 1 eye
safety per IEC60825 and CDRH standards.
The receiver has a hermetically packaged APD-TIA (trans-impedance amplifier) pre-amplifier and a limiting amplifier with
LVPECL compatible differential outputs. It features a loss of signal(LOS) output which is LVTTL compatible. The LOS
output will come low after receiving the burst packet.
The module provides digital diagnostic information of its operating conditions and status, including transmitting power, laser
bias current, module temperature, and supply voltage.
