Bidirectional | Alker Fibre Optic Specialists

Bidirectional

The ability for light to transmit in both directions through a fiber. Fibers are generally used in pairs, with one fiber carrying a signal one way, and the other fiber carrying it the other way. However, bidirectional communications is possible over one fiber strand by using two different wavelengths and appropriate coupling/splitting devices. Bidirectional couplers split or combine light the same way when it passes through them in either direction.
