Description of Hardware
The EC3002 is an FTTH CPE product for high-speed Internet access applications.
The CPE includes an embedded fiber cable connection, an RJ-45 Ethernet port, a
DIP-switch for the RJ-45 port settings, an internal DIP switch for Auto MDI-X, flow
control and port speed, 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 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-FX 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 from the CO.
UTP Port
The RJ-45 Ethernet port labeled “UTP” operates at 10 or 100 Mbps, and supports
auto-negotiation of speed, duplex mode (i.e., half or full duplex), and flow control.
The UTP port can also be forced to a specific speed and duplex mode via a
DIP-switch setting. Using the DIP switch you can also set the port for MDI or MDI-X
operation, so you can use straight-through cable for all connections.
