18.3.4 Optical Performance for Single-Span Networks
18.3.4 Optical Performance for Single-Span Networks
lists the span loss for a single-span link configuration with eight channels. The optical
performance for this special configuration is given only for Classes A and C. This configuration assumes
a maximum channel capacity of eight channels (8-dBm nominal channel power) used without any
restrictions on the 32 available channels.
lists the span loss for a single-span link configuration with 16 channels. The optical
performance for this special configuration is given only for Class A and Class C. This configuration
assumes a maximum channel capacity of 16 channels (5-dBm nominal channel power) used without any
restrictions on the 32 available channels.
