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.
6. 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.
