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
3
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
-15
BER.
