100GHz 200GHz 16 channels 18 channels DWDM MUX/DEMUX Module
China [CN] Dense wavelength division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of erbium doped fiber amplifiers (EDFAs), which are effective for wavelengths between approximately 1525–1565 nm (C band), or 1570–1610 nm (L band).
DWDM Module Dense WDM can solve the shortage of fiber resources and transparent transmission of business, and reduce the cost of network Construction. With low-cost and compact dimension, it is mainly used in metropolitan area network and access layer, also be used to build networks.
