Notes:
1. Measured average power coupled into 62.5/125um fibre with NA = 0.275. Class 1 eye safety per
FDA/CDRH, IEC, and EN60825-1 safety standards.
2. Also specified to fall within the extrapolated curves in FDDI PMD
3
Figure 9, which allow trade-off
between wavelength, spectral width and transmitter rise/fall times.
3. Unfiltered, 10-90%.
4. Unfiltered, 20-80%.
5. Peak-to-peak measurement for OC-3 SR-0 or OC-1 SR-0 operation measured with a PRBS 2^23-1 test
pattern.
6. Peak-to-peak measurement based on 4B/5B encoded Fast Ethernet pattern referenced in FDDI PMD

Annex A.5
7. Specifications are for 50 micro-meter or 62.5 micro-meter fiber.
8. Specifications are for 50 micro-meter or 62.5 micro-meter fiber, based on any valid 8B/10B code
pattern and measured at, or extrapolated to, 10
