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.
