Wholesaler price 19 Inch 1 U 18CH Rack-mounted CWDM
Products Description
An optical industry interim standard uses up to eight wavelengths, this scheme is referred to as coarse wavelength division multiplexing(CWDM), in accordance with ITU-T(any channel spacing between 8 and 50 nm). ITU-T Recommendation approved in June 2014, extends this down to 1270 nm(18 wavelengths), anticipating the ready commercial availability of fiber with no "water peak" of loss between the 1310-nm and 1550-nm transmission windows, as discussed in Chapter. Such an extended-wavelength planis, of course, applicable only to nonamplified systems until such time as optical amplifiers with similarly extended bandwidths are developed.
