6.3.2 Optical bands
Each input port can be optimised for a different wavelength band.
There are four optical bands numbered from 0 to 3. Bands 0, 1 and 2
are factory optimised using lasers in the blue (400 nm), red (600 nm)
and infra-red (1100 nm).
The normal configuration is as shown in the table below. Band 3 can
