Chapter 5 Multiplexer and Demultiplexer Cards
5.1.3 Interface Classes
Table 5-5 lists the optical interface performance parameters for 2.5-Gbps cards that provide signal input
to multiplexer and demultiplexer cards.
10-Gbps multirate

1. OSNR = optical signal-to-noise ratio
2. BER = bit error rate
3. These values, decreased by patchcord and connector losses, are also the input power values for the OADM cards.
