6. 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.

7. 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.

8. 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.
