Olt Sfp Transceiver


2.5Gbps Gpon Sfp Transceiver

Product Description

1490nm 2.5Gbps Gpon Olt Sfp 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.
