The Avanex pureform DCM smfc-20 is a passive optical dispersion compensation module designed to counteract chromatic dispersion in standard single-mode fiber within the C-Band. The smfc-20 designation indicates compensation for approximately 20 km of ITU G.652 fiber, including SMF-28 compatibility. This module reduces accumulated residual dispersion to enhance signal integrity in long-haul and metropolitan network deployments, with particular effectiveness in DWDM systems operating at high bit rates.
