Notes:
1. Equivalent extinction ratio specification for Fiber Channel. Allows smaller ER at higher average power.
2. Measured at nominal data rate. These are unfiltered 20%~80% values.
3. Transmitter Dispersion Penalty is measured using the methods specified in the IEEE standard 802.3-2005 Clause
52 except that the transversal filter differential delay is 33 ps.
4. The sensitivity is tested at a BER of 1×10
-12
or better with an input signal consisting of 2
7
-1 NRZ PRBS.
5. Distance, shown in the “Link Length” table, are calculated for worst case fiber and transceiver characteristics
based on the optical and electrical specifications shown in this document using techniques utilized in IEEE 802.3.
In the nominal case, longer distances are achievable.
