1. General Description
The OAT6223S-ONU-V5-A/B optical transmission module is compliant with recommendation of ITU-T
G.983.3 class A/B for use in ATM-PON application. The OAT6223S-ONU-V5-A/B is applicable for the
optical interface of ONU which is located on the subscriber side. These modules have the following
functions.
-1-fiber bi-directional transmission by incorporated wavelength division multiplexer (WDM).
-Conversion of 622.08Mbps electric signal to 1.3um optical signal by laser diode (E/O conversion).
-Stabilization of optical output power and waveform with laser diode driving current temperature
compensation circuit.
-Transmit failure (TF) detection.
-Optical signal output shut down (LS).
-Conversion of 622.08Mbps 1.49um optical signal to electric signal by PIN-photo diode (O/E conversion).
-w/ Blocking Filter
-w/ CDR functions.
-Incoming signal lost detection (LOS).
The specifications are shown on the table 1.1
