It is designed for use in small form-factor pluggable (SFP) transceivers and other types of optical modules for high-speed telecommunication and data applications including WDM SONET OC-48, SDH STM-16, Fibre Channel, and Gibabit Ethernet. 2 wavelengths from 1470nm to 1610nm in 20nm increments. It is a flexible plug-and-play network solution that allows network operators to cost effectively i lm filter technology dicate the wavelength of the individual CWDM transceivers. The CWDM and DWDM systems are transparent to all the. The RFoG WDM module is designed to satisfy wavelength management requirements where 1310, 1490, 1550 and 1590 / 1610nm wavelengths are used in passive optical network applications. This unit is available in traditional LGX module packaging with virtually all connector options supported. There are eight center. The CWDM Mux Demux support ITU-T G.
