1. General Description
The OAT1521S-ONU-V4-B-10 optical transceiver is compliant with recommendation of ITU-T G.983.1
/ 983.3 option1 class B for use in ATM-PON application. It is applicable for the optical interface of the ONU
/ONT 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 156Mbit/s 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 156Mbit/s 1.55um optical signal to electric signal by PIN-photo diode (O/E conversion).
- w/ CDR function
-Incoming signal lost detection (LOS).
The specifications are shown on the table 1.1
