Table 4. EEPROM Serial ID Memory Contents - Address A2h
Notes:
1. Temperature (Temp) is decoded as a 16 bit signed twos compliment integer in increments of 1/256 °C.
2. Supply voltage (VCC) is decoded as a 16 bit unsigned integer in increments of 100 V.
3. Laser bias current (Tx Bias) is decoded as a 16 bit unsigned integer in increments of 2 A.
4. Transmitted average optical power (Tx Pwr) is decoded as a 16 bit unsigned integer in increments of 0.1 W.
5. Received average optical power (Rx Pwr) is decoded as a 16 bit unsigned integer in increments of 0.1 W.
6. Bytes 55-94 are not intended from use with AFCT-5745Z, 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.
