GEPON OLT For P2MP Application
The SFE2134-DMx transceiver with supports a data rate of typical 1.25 Gbps for GEPON
OLT application up to 20km transmission distance, it’s designed meeting with China Telecom
EPON equipment technical requirement V2.1 1000BASE-PX20+/PX20++/PX20+++ 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.
