1. General Description
The OAT6221S-ONU-V5-B optical transmission module is compliant with recommendation of ITU-T
G.983.3 class B for use in ATM-PON application. The OAT6221S-ONU-V5-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 1.49um optical signal to electric signal by PIN-photo diode (O/E conversion).

8. Precautions for handling
The circuits of these modules operate at very small signal. In order to avoid the degradation of the
optical sensitivity due to external noise, the bottom pattern of these modules on the PCB should be ground
pattern with low impedance.
Do not mount/pattern device/circuits which generate high frequency noise close to the module.
In order to operate the module stable against the power noise, install the power supply noise reduction
circuits.
The impedance between the power and ground pattern of the power circuit should be as low as possible. The
elements around the module should be mounted close to the pins of the module.
If an optical power exceeding the absolute maximum ratings is fed to the module, the optical receiver may be
damaged. Set the optical input power appropriately when in use of these modules.

9. Qualification and Reliability
To help ensure high product reliability and customer satisfaction, OKI is committed to an intensive quality
program that starts in the design phase and proceeds through the manufacturing process.
Optical transceiver modules are qualified to OKI internal standards using MIL-STD-883 test methods and
procedures and using sample techniques consistent with Telcordia requirements.
This qualification program fully meets the intent of Telcordia reliability practices GR-468-CORE.


10. Laser Safety
All version of transceiver are Class 1 Laser products FDA complies with 21 CFR 1040.10 and 1040.11
requirements.
Also, all versions are Class 1 Laser products pre IEC 825-1.
