Product Applications
GEPON OLT For P2MP Application
General
The HDV ZL5432099-ICS transceiver with supports 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+ specifications. SC rececptacle 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.

High (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled
Mod-Def 0 is grounded by the module to indicate that the module is present
Mod-Def 1 is the clock line of two wire serial interface for serial ID
Mod-Def 2 is the data line of two wire serial interface for serial ID
4. LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicates the received optical power is below the worst-case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
