1. General Description
The OAT6221S-ONU-V4-B optical transmission module is compliant with recommendation of ITU-T
G.983.1 class B for use in ATM-PON application. The OAT6221S-ONU-V4-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 155.52Mbps 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 1.55um optical signal to electric signal by PIN-photo diode (O/E conversion).
- w/ CDR functions.
-Incoming signal lost detection (LOS).
The specifications are shown on the table 1.1
