CWDM 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.

We now offers a compact CWDM module that provides bandwidth capacity expansion for future network growth in one of the small packages. Its compact size and unique carrier tray set it apart, and can be installed in a variety of field situations. Speed Photon’s compact CWDM is based on thin film filter technology and available in 4-or 8-channel configurations. Optical performance is excellent with low insertion loss and excellent temperature stability.
