Product Details
CWDM Mux/Demux Module are based on thin film filter technology.
CWDM technology provides the flexibility to increase capacity of
existing fiber infrastructurby enabling multiple channels
(wavelengths) over the same fiber cabling. Eacchannel carries data
independently from each other, allowing network designers to
transport different data rates and protocols for different
customers or applications. CWDM can solve the shortage of fiber and
transparent transmission of business, and reduce the cost of
network building. With low-cost low power consumption and
smalcompact, it is widely used in metro aggregation and access
layer to do transmission on a short time. UNIFIBER CWDM Mux/Demux
products provide up to 16-channel or even 18-channel Multiplexing
on a single fiber. Standard CWDM Mux/Demux package type include:
ABS box package, LGX package and 19" 1U rack-mount.
