Fiber optic switch ab ends
Achieve this with WDM (wavelength division multiplexing): each end transmits and receives on different wavelengths over the same strand. For example: End A: TX 1310 nm, RX 1550 nmEnd B: TX 1550 nm, RX 1310 nm Other BiDi pairs exist. Fiilex Fiber A/B Switch is an all-optical solution designed to seamlessly toggle between primary and secondary paths, so users can switch between network resources, primary and secondary equipment, or secured and unsecured com-munication lines. Patent nos: 5574813, 5751874, 5761359, 5769698, D409154, 5781285, 5818993, 6503422, 6095694, D780136, 9880358, Patents pending. Since fiber optic links require a two-way - or duplex - connection, there is potential for. The dry contact closure remote interface can be connected directly to SecureSwitch revision B.
