Introduction
Thank you for purchasing a StarTech.com Single-Mode WDM Media
Converter. This product offers a cost-effective method of bridging
two Ethernet networks using single-mode fiber optic cable, at dis-
tances up to 40km (24.85 miles).
Features
• Simple installation and use
• Supports full or half-duplex operating modes
• Supports link-loss forwarding, loop-back testing, remote monitor
status, two frame lengths
Before You Begin
System Requirements
• Fiber Cable
• 10Base-T; Cat 3, 4 or 5
or 100Base-Tx, Cat 5 or 6 cable
• Power source
Contents (per unit)
• Media Converter (1)
• 12V DC Power Adapter (1)
• Instruction manual (1)
Basic Setup
1. Connect the fiber interface cable to the A-Unit. Using UTP cable,
connect the ethernet connection to the RJ45 jack.
2. Set the Duplex switch (full/half) according to the specifications of
your equipment.
Media Converter Connections
The following example illustrates the connection scheme when
connecting from a 1000Base-TX port of one hub to a 1000Base-
SX/LX port of another hub, through the fiber converter:

converter:
Front Panel DIP Switch Settings
1. Full/ Half:
The Fiber and UTP Duplex will be configured in Full-duplex or Half-
duplex. *This switch includes an “Auto Reset” function so the
power-reset is not necessary when any modification is made
here.
2. LBT - Loop-back test and get remote side status :
(OFF = Not Active, ON = Active) Please note: If the local side
loop-back test is active, then LEDs (except PWR) will all blink
rapidly and refresh to display the remote side status.
3. LLF - Link Loss Forwarding (OFF = Not active, On = Active)

Link-Loss-Forwarding (LLF)
ET91000SM40 incorporates a Fiber Link Forwarding feature that
allows indirect sensing of a Fiber Link Loss via the 1000 Base-TX
UTP connection. Whenever the media device detects a Link Loss on
the Receive fiber (Fiber LNK OFF), it disables its UTP transmitter so
that a Link Loss condition will be sensed on the receive UTP port (as
depicted in the following diagram). The Link Loss can then be easily
monitored and reported at the remote UTP port’s host equipment.
This feature has no effect on the media converter’s UTP LNK LED,
which continues to function normally, independent of the state of the
Fiber LNK LED and the UTP transmitter. This feature enabled by
default.

Loop-back Testing (LBT)
& Get CPE status
ET91000SM40 incorporates a Fiber Loop-back Testing feature which
allows the system to confirm whether or not the fiber or Ethernet cir-
cuit loop is complete. The local-side unit will send out a detect mes-
sage which includes both command and test-pattern data to the
remote-side unit and request for an answer. When the remote-side
unit receives the message, it will attempt to recognize the command.
After the remote-side unit recognizes the command message, it will
deliver the received test-pattern data back to the local-side unit, com-
pleting the circuit loop, and enabling the rack mount unit to easily
monitor the remote side unit(s). The remote side status message
includes the fiber-side link and duplex status, the UTP-side link,
duplex, speed, power, transmission and fiber failure status.
Please note that while Loop-back testing is in process, the fiber side
transmission will be halted.
If the local-side cannot access the remote-side while in Loop-
back Testing mode, only the power LED will flash (rapidly):
