blocker based OADM (optical network) (BOADM)

BOADM, Blocker Based OADMs, are reconfigurable optical add/drop multiplexers(OADM) that use Wavelength Blockers( WB) and can be configured remotely.

Wavelength blockers can block entire frequency bands or multiple wavelengths and attenuate the level of light signals. The wavelength blockers use switches in microsystem technology or in LCoS technology.
