2.2.6 Transponder, Muxponder, and Optical Cards

For DWDM system interoperability, the operating center frequency (wavelength) of channels must be the same at the transmitting and receiving ends. Channel selection (center frequency) and channel width determine the number of nonoverlapping channels in the spectrum. Channel width, wavelength, bit rate, fiber type, and fiber length determine the amount of dispersion. Channel separation allows for a frequency deviation of approximately 2 GHz, caused by frequency drifts in the laser, filter, and amplifier devices to avoid interchannel interference.

The ITU-T currently recommends 81 channels in the C band, starting from 1528.77 nm and incrementing in multiples of 50 GHz to 1560.61 nm.

All C-band TXP and MXP cards support a range of wavelengths in increments of 100 GHz, as shown in Table 2-29.
