Introduction
Fiber-To-The-Home (FTTH) has always been an attractive option for Internet
access. It has all the benefits of optical fiber. It provides a future-proof network, in
that you do not have to go through the hassles of upgrading from ADSL to xDSL, or
digital co-ax to digital wireless. It does not have to struggle with electromagnetic
interference problems, and with no active “outside-plant” components, it offers the
highest reliability. Moreover, it does not require electric power and is immune to
lightning and other transients. These properties of fiber lead to the lowest possible
power and operational costs, such as maintenance, provisioning and facilities
planning.
The EC3802-WDM Media Converter is an ideal Customer Premises Equipment
(CPE) for an FTTH system. This CPE is a single-channel fiber-to-copper media
converter housed in a compact unit. It allows a service provider to extend an
Ethernet connection over optical fiber directly to a subscriber. The CPE has an
embedded (no external plug/socket) ITU-T G.985 full-duplex single-fiber
single-mode cable connection that runs from the service provider’s central office
(CO). The single-mode fiber connection can be run up to distances of 15 km from
the CO. The CPE also provides one standard 10/100BASE-TX RJ-45 Ethernet port
for connecting to a customer’s PC, switch, or other network device using twisted-pair
cable.

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 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.

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), flow control, and
MDI/X pinout selection. Automatic configuration of MDI or MDI-X pinout operation,
allows you to use straight-through cable for all connections. Where necessary, the
UTP port can also be forced to a specific speed and duplex mode via a DIP-switch
setting.
Note: The CPE may also receive Power over Ethernet (PoE) from a switch or other
network device that supplies power over the network cable based on the IEEE
802.3af standard. If the CPE is connected to a PoE source device through the LAN
port and also connected to a local power source through the AC power adapter,
PoE power will be used and input from the AC power adapter disabled.
Power Connector
The CPE does is powered on when the power adapter is connected to a power
source. The power adapter automatically adjusts to any voltage between 90~240
volts at 50 or 60 Hz. No voltage range settings are required.
Note: The CPE may also receive Power over Ethernet (PoE) from a switch or other
network device that supplies power over the network cable based on the IEEE
802.3af standard. If the CPE is connected to a PoE source device through the LAN
port and also connected to a local power source through the AC power adapter,
PoE power will be used and input from the AC power adapter disabled.

Making a Connection to the UTP Port
The UTP port on the CPE supports automatic MDI and MDI-X pinout selection. This
allows you to use standard straight-through twisted-pair cables to connect to any
other network device (computers, switches, routers, or hubs).
See “Port and Cable Assignments” on page 26 for more information on connecting
straight-through or crossover UTP cables to MDI or MDI-X ports.
Caution: Do not plug a phone jack connector into any RJ-45 port. This may damage the
CPE. Instead, use only twisted-pair cable with RJ-45 connectors that conform
with FCC standards.
To connect the CPE’s UTP port directly to a computer, carry out the following steps:
1. Prepare the computer you wish to connect. Make sure you have installed a
10BASE-T or 100BASE-TX network interface card for connecting to the CPE’s
UTP port.
2. Check that the CPE’s UTP port has auto-negotiation enabled by setting the
“Auto” DIP-switch to ON. If you manually set the speed and duplex mode, be
sure that the CPE and computer’s network interface card settings match.
3. Prepare straight-through shielded or unshielded twisted-pair cable with RJ-45
plugs at both ends (not included in the CPE package). Use 100-ohm Category 3
or greater cable for 10 Mbps Ethernet connections, or 100-ohm Category 5 or
greater cable for 100 Mbps Fast Ethernet connections.
4. Connect one end of the cable to the RJ-45 port of the computer’s network
interface card, and the other end to the UTP port on the CPE. When inserting an
RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is
properly seated.
