Optical Switch for Diverse Routing
Optical Switch for Diverse Routing The BC2x1SW is an optical switch designed to offer system designers increased flexibility in their fibre installations. Two separate optical inputs A and B are fed into the single slot BC Series card. Internal logic on the card senses the light levels of the inputs and will switch from a main to reserve path in the event of signal loss. By routing two separate diverse fibres to the A and B inputs automatic switchover will occur in the event of a failure in the transmission path caused by a faulty fibre or connector. The sensitivities at which the changeover occurs can be user defined to suit the installation increasing user confidence. A BCSPLIT is used upstream to provide a 50:50 optical feed to the separate optical fibres. Passive splitters can be provided with different ratios of output light levels. The BC2x1SW occupies a single slot in any of the BC Series 19″ rack-mounting frames. For stand alone applications the BC2x1SW can be housed in an individual rugged enclosure.
