Abstract

Fiber optic switches which use the "moving fiber" principle to obtain low insertion loss and mode independence are discussed. Because the precisely-cleaved endfaces of the fibers are accurately aligned in close proximity, most of the modes can be transferred, and losses kept to a minimum (typically 0.6 dB). Due to the mature technology of electromechanical relays, and the low inertia associated with moving fibers instead of moving mirrors, prisms, or lenses, the switches are very reliable. Both bypass and fully-reversible versions will be discussed. The loopback capability of the fully-reversible switch makes possible an extended range of applications, including dual attachment station bypass and self-healing ring "wrap around".
