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

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 switch (full/half) according to the specifications of Duplex

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:

The following example illustrates the connection scheme when con-

necting from a 1000Base-TX port of one hub to a 1000BASE-TX

Network Interface Card (NIC) in a computer through the fiber

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) If the local side Please note:

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):
