Notes:
1. LED wavelength is represented in 16 unsigned bits. The hex representation of 650 (nm) is 0x28A.
2. Address 68-83 specify a unique module serial number.
3. Address 84-91 specify the date code.
4. Address 63 is the checksum for bytes 0-62 and address 95 is the checksum for bytes 64-94. They are calculated (per SFF-8472) and stored prior
to product shipment.
5. Address 96-127 is vendor specic.

Notes:
1. Temperature (Temp) is decoded as a 16 bit signed twos complement integer in increments of 1/256 °C.
2. Supply voltage (Vcc) is decoded as a 16 bit unsigned integer in increments of 100 µV.
3. Received optical modulation amplitude margin or Rx OMA margin is a measure for the reserve in OMA to Sensitivity.
4. Received OMA margin is decoded as an 8 bit signed twos compliment integer in increments of 0.2 dB.
5. This register is read only. A write will be acknowledged but not stored.
6. Bytes 56-94 are not intended for use with AFBR-5978Z, 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.
8. Reserved registers will return “00” when read. A write to a reserved register will be acknowledged but not stored.
