Coarse Wavelength Division Multiplexer/Demultiplexer
Coarse Wavelength Division Multiplexer/Demultiplexer The BC-4 is a passive device for the multiplexing or demultiplexing of different optical wavelengths onto or from a singlemode fibre optic cable. Each unit allows up to 4 channels to be combined /separated with a 20 nm wavelength spacing based around the ITU G.694.2 grid specifications. Adding additional BC-4 or BC-8 cards allows the system to transmit a total of 16 independent wavelengths on a single fibre, proving to be a very cost effective solution for system designers working with third party leased fibres or in Outside Broadcast. The BC-4 occupies a single slot in any BC Series 19″ rack-mounting frames. This module is designed for applications where space is at a premium, ideal for portable OB systems when fitted in the BC160/BC160P units. The BC-4D occupies two slots in any BC Series 19″ rack-mounting frames. This module can be used for cost effective installations where space is not critical. The BC160P 19″ 1RU frame is specifically intended to house passive optical modules including splitters, WDM and CWDM devices. When used in combination with the active frames they produce ultra compact optical multiplexing and distribution systems. For stand alone applications the BC-4 can be housed in an individual BC120 rugged enclosure.
