Fiber Cable Connection
The single-mode fiber cable connection from the service provider’s CO is embedded (connected internally) within the CPE. There is no external plug and socket connection, which prevents the CPE from being disconnected accidently. Also, there are no configuration settings or maintenance necessary for the fiber cable link.
The single-fiber connection supports a 100BASE-BX full-duplex link to the CO. The CPE’s fiber transceiver uses Wavelength Division Multiplexing (WDM) technology to achieve bi-directional operation (1550 nm transmit, 1310 nm receive) over a single optical fiber. The WDM single-mode fiber link can run up to 15 km (9.32 miles) from the CO.
