Specifications for each channel

The BC-2 is a passive device for the multiplexing or demultiplexing of two optical wavelengths onto or from a single fibre optic cable.

The BC-2 operates with 1310 and 1550 nm wavelengths on singlemode fibres. The BC-2/M works with 850 and 1310 nm wavelengths on multimode networks.

As standard transmitters and receivers are used, overlaying an extra wavelength via WDM, proves to be a very cost effective solution for system designers looking to increase capacity on existing networks.
This can be particularly true in legacy multimode networks.

One WDM module is used to combine the two separate wavelengths while a second at the receive end separates the two signals again.

Bidirectional links also prove very cost effective using this method.

The BC-2 occupies a single slot in the BC100-3RU 19" rack-mounting frame which can hold up to 15 single slot cards. Some BC Series processing cards have dual functionality allowing up to 30 channels of video to be transmitted or received from a single 3RU frame.

For stand alone applications the BC-2 can be housed in an individual rugged enclosure.
