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 PMD3 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 PMD3 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, 10-15BER.
