General

The BD-N12-S20C transceiver with SFF 2*10 package supports typically 1.244 Gbps Tx,2.488 Gbps Rx Asymetric Data Rate for GPON ONU application up to 20km transmission distance, it’s designed meeting with ITU-T G.984.2 Class B+. SC rececptacle or SC/PC pigtail is for optical interface.


Fig 1 Transceiver Block Diagram

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.
