Product Applications

l  GPON ONU For P2MP
Application

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.

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.
