Description
Coarse Wavelength Division Multiplexing is a type of optical wavelength management device that are based on proven thin-film filter technology. It features small size, high reliability, high extensibility, simultaneous transmission multi-wavelength; CWDM has gained prevalence in multi-wavelength digital transport architectures because it enables the use of very low cost un-cooled DFB laser transmitters. Moreover, powering requirements are reduced and reliability is increased.
Ingellen provides whole series of 1xN CWDM products that are tailored for specific applications. All products meet GR-1209-CORE,GR-1221-CORE and ITU-T G.694.2 requirements.
