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 for use with AFCT-57J7ATPZ, but have been set to default values per SFF-8472.
7. Byte 95 is a checksum calculated (per SFF-8472) and stored prior to product shipment.
