Compatible Huawei 2.5G Gpon Olt Sfp Optical Transceiver Module
Gpon Olt Sfp Tx1490nm Rx1310nm SC Fiber Optic Transceiver
Description of GPON OLT SFP Module
The SOPTO GPON OLT SFP transceiver with supports data rate of
typical 2.488 Gbps for GPON OLT application up to 20km transmission
distance, it’s designed meeting with ITU-T G.984.2 Class B+/ C+/
C++ specifications. SC receptacle is for optical interface.
The module provides digital diagnostic information of its operating
conditions and status, including transmitting power, laser bias,
receiver input optical power, module temperature, and supply
voltage. Calibration and alarm/warning threshold data are written
and stored in internal memory (EEPROM).The memory map is compatible
with SFF-8472, as shown in Fig. 2. The diagnostic data are raw A/D
values and must be converted to real world units using calibration
constants stored in EEPROM locations 56 – 95 in A2h.
