GEPON OLT PON Module,Class C++, 7dBi, 20Km

WDS5441H-C(H)3AL is a high performance transceiver module for single fiber communications using a 1490nm continuous-mode transmitter and a 1310nm burst-mode receiver. It is designed to meet CTC 3.0 and IEEE802.3ah -2004 1000BASE- PX20+++ applications.
The transmitter has automatic power control (APC) function and temperature compensation circuitry to ensure stable optical power output and extinction ratio over all operating temperature range. The transmitter meets Class 1 eye safety per IEC825 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 burst-mode Loss of signal (LOS) output which is LVTTL compatible. The receiver offers bust-mode RSSI outputs, which is I2C
accessible digitized data stored in the internal flash memory.
The module provides digital diagnostic information of its operating conditions and status, including transmitting power, laser bias current, module temperature, supply voltage, and burst-mode receiving power. Calibration and alarm/warning threshold data are written and stored in the internal memory (EEPROM). The memory map is compatible with SFF-8472.
Compatible with all Wodaplug OLT units and all other with this standard
