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 then 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 at the upstream transmission point. 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.
