Description of Hardware
The EC3802-WDM is an FTTH CPE product for high-speed Internet access
applications. This CPE includes an embedded fiber cable connection, an RJ-45
Ethernet LAN port, PoE on the LAN port, a DIP-switch for LAN port settings, LED
status indicators, and an AC power adapter connection.
The following figure shows the components of the CPE.

Fiber Cable Connection

The single-mode fiber cable connection from the service provider’s CO is e mbedded
(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.
