Introduction
Fiber-To-The-Home (FTTH) has al ways been an attractive option for Internet
access. It has all the benefits of opt ical 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 elec tr om a gnetic
interference problems, and with no active “outside-plant” components, it offers the
highest reliability. Moreover, it does not require electric power and is i m m une 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 Medi a Converter is an ideal Customer Premises Equipment
(CPE) for an FTTH system . T his C PE is a single-channel fiber-to -c opper media
converter housed in a com pact unit. It allows a service prov i der to ext en d an
Ethernet connection ove r op tical 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 s er vi ce provider’s central office
(CO). The single-mod e fib er connection can be run up to distances of 15 km from
the CO. The CPE also provides one standard 10/100BASE-TX RJ-45 Et her net port
for connecting to a customer’s PC, switch, or other network device using twisted-pair
cable.

Fiber Cable Connection
The single-mode fiber cable connection from the service provider’s CO is embedded
(connected internally) w ithin 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 100B ASE-BX full-d uplex link to the CO. The
CPE’s fiber transceiver uses W a velength Divis ion Mult iplexing (WDM) technol ogy to
achieve bi-directional operation (1550 nm transm i t, 13 10 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.

Description of Hardware
UTP Port
The RJ-45 Ethernet port lab eled “UTP” operates at 10 or 100 M bps, and supports
auto-negotiation of speed, duplex mode (i.e., hal f or fu ll du pl ex) , flow control, and
MDI/X pinout selection. Autom atic configuration of MDI or MDI-X pinout operation,
allows you to use straight - th ro ugh cable for all connections. Where necessary, the
UTP port can also be forced to a s pecific 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 w he n th e 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 set t in gs 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 sele ction. This
allows you to use standard str ai ght-through twisted-pair cables to connect to any
other network device (com puters, switches, route rs , or hu bs) .
See “Port and Cable Assignments” on page 26 for more information on connecting
straight-through or cro sso ver 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 compu te r, carry out the following st eps:
1. Prepare the computer you wis h to connect. Make sure you have ins talled a
10BASE-T or 100BASE-TX network interfac e car d for con nec tin g to the CPE’s
UTP port.
2. Check that the CPE’s UTP port has aut o- negotiation enabled by set ting th e
“Auto” DIP-switch to ON. If yo u manually set the speed an d duplex mode, be
sure that the CPE and computer’s network inte rface 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 Ethe rn et connections, or 100-ohm C at eg or y 5 or
greater cable for 100 Mbps Fa st Eth ernet connections.
4. Connect one end of the ca bl e to th e 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.
20
Installing the FTTH CPE
Notes: 1. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).
2. We advise using Category 5 cable for all network connections to avoid any
confusion or inconvenience in the future when you upgrade devices to Fast
Ethernet.
Powering On the CPE
Plug the AC power adapte r direct l y int o a power outlet. Check the LED mar ked
“PWR” on the front panel to be sure it is on.
Otherwise, the CPE can derive its operating power directly from the LAN port when
connected to a device th at pro vides IEEE 802.3af compliant Pow e r ov er Ethernet.
If the CPE is connected to both a PoE source device and an AC power source, PoE
is used, and input from the AC a dapter disabled.
Configuring the TCP/IP Protocol
To connect to the Internet through the CPE’s Ethe rn et por t, a computer must have
an Ethernet network interface card installed, and be configure d f or the TC P/IP
protocol. Many service pr oviders will configure TCP /IP f or client computers
automatically using a net working technology know n as Dynamic Host Config ur at io n
Protocol (DHCP). Other service providers may specify an IP configuration (known as
a static IP address), which must be entered manuall y.

You can upgrade new CPE softwar e from a l ocal file on a PC attached to the LAN
port. New software may be provided periodically from your distributor.
The IP address for the CPE’s web interface is 192.168.252.1. Before upgrading new
software, verify that your PC is configured with an IP address within the same
network subnet (that is, 192.168.252.x).
Note: The Status page provides information on the CPE’s IP address, MAC address,
hardware version, and serial number.
To upgrad e f irm war e on the CPE, follow these steps:
1. When the logon screen appears, enter “admin” for bot h th e user name and
password.
2. When the Default Page is displ ayed, click System.
3. When the System Startup Page is displayed, cl ick Fi r m w ar e U pg ra de.
4. Use the Browse function to select th e new firmware from your local PC.

Port and Cable Assignments
RJ-45 Ethernet Port
Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair
cables with RJ-45 connectors that conform with FCC standards.
An Ethernet twisted-pair link segment requires two pairs of wires. Eac h w ire pair is
identified by two different colors. Each wire pair must be attached to the RJ-45
connecto r in a specific orientation detailed below.
The RJ-45 Ethernet port on the FTTH CPE can be set as an MDI or MD I-X po rt,
which allows straight-through cable to be used for a connection to a computer,
switch/hub, or other net wo r k d evi ce. In straight-through cable, pins 1, 2, 3 and 6 at
one end of the cable, are connected straight-throu gh to pins 1, 2, 3 and 6 at the
other end of the cable.

Straight-Through Wiring
If the twisted-pair cable is to join two ports and only one of the ports has an inter nal
crossover (MDI-X), the two pairs of wires must be straight-through. (The CPE RJ-45
port auto-negotiates MDI or MDI-X pinout selection, al lo wi ng you to use either
straight-thorough or cr ossover cable when conn ect i ng to an ot her network device.)

Crossover Wiring
If the twisted-pair cable is to join two ports and either both ports are labele d w ith an
“X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be
implemented in the wiring. (The CPE RJ-45 port auto-negot iat es M D I or MDI - X
pinout sel ection, allowing you to use either straight-thorough or crossover cable
when connecting to ano t her net w ork device.)
