Notes:

1. Temperature (Temp) is decoded as a 16 bit signed twos compliment integer in increments of 1/256 °C.

3. Laser bias current (Tx Bias) is decoded as a 16 bit unsigned integer in increments of 2 μA.

4. Transmitted average optical power (Tx Pwr) is decoded as a 16 bit unsigned integer in increments of 0.1 μW.

5. Received average optical power (Rx Pwr) is decoded as a 16 bit unsigned integer in increments of 0.1 μW.

6. Bytes 55-94 are not intended from use with AFCT-5765xxxx, but have been set to default values per SFF-8472.

7. Bytes 95 is a checksum calculated (per SFF-8472) and stored prior to product shipment.

8. Byte 127 accepts a write but performs no action (reserved legacy byte).

9. Bytes 128-247 are write enabled (customer writable).

10. Byte 255 bits 2 and 3 control laser margining (per Table 7) when an enabling password is entered into bytes 123-126.
