Optical WDM Transport

Wavelength-division multiplexing lets operators carry many optical channels on a single fiber pair, stretching scarce dark fiber between halls, campuses, and metro DCI sites.

A typical stack combines passive Mux/Demux, optional OADM drops, line amplifiers, and pluggable DWDM optics matched to channel plans and OSNR targets.

CWDM suits shorter metro spans with lower channel counts and simpler optics. DWDM unlocks denser channel plans and longer reaches when paired with amplification and dispersion management.

Engineering review should confirm connector types, monitor ports, and spare channel strategy before locking the BOM for multi-site rollouts.
