Notes:

1. The IEEE Organizationally Unique Identifier (OUI) assigned to Avago is 00-17-6A (3 bytes of hex).

2. Laser wavelength is represented in 16 unsigned bits.

3. Addresses 63 and 95 are checksums calculated (per SFF-8472 and SFF-8074) and stored prior to product shipment.

4. Addresses 68-83 specify the ASCII serial number and will vary on a per unit basis.

5. Addresses 84-91 specify the ASCII date code and will vary on a per date code basis.
