Functional Diagram
The Signal Detect (SD), Logic “1” represents the normal optical input level.
The following versions are available:
1. DC/AC Transceiver
Standard PECL inputs and CML outputs, TX is DC coupling and RX is AC coupling.
Product Description
Eoptolink’s high performance GPON ONU transceiver is designed for passive optical network
application. It can fully support the Class B+ ODN application specified by the ITU-T G.984.2
standard and ITU-T G.984.2 Amendent1.
The GPON ONU transceiver is packaged of small form factor 2x10 with a pigtail and SC connector.
The digital diagnostic monitoring function is compliant with SFF 8472 MSA.
The module consists of 1310nm un-cooled DFB Laser, InGaAs preamplifier and WDM filter in a

Enhanced Digital Diagnostic Interface
The memory map in the following describes an extension to the memory map defined in SFF-8472
MSA. The enhanced interface uses the two wire serial bus address 1010001X (A2H) to provide
diagnostic information about the module’s present operating conditions.
