Overview

This document contains instructions necessary for the installation
and operation of the Perle Protocol Transparent Standalone Media
Converters. These Media Converters allow connection and cross­connection of fiber networks of different types to each other. They
are protocol independent using standard SFP* modules with
speeds up to 4.25 Gbps.

*(purchased separately)

Supported modes of operation

o Multimode to multimode
o Multimode to single mode
o Single mode to single mode
o Multimode to single Mode Single strand
o Wavelength Transponder (CWDM/DWDM)
o Dual and single fiber (Simplex to Duplex)

Key Features

o Protocol and rate transparency for fiber SFPs
o Support for all standard MSA-complaint SFPs
o SFP rates from 1 up to 4.25 Gbps
o Support for multi-rate SFPs
o Smart Link Passthrough
o Fiber Fault Alert
o Provides diagnosis LED functions
o Extended Temperature models available

Installation

The default switch settings (all switches in the UP position) will
work for most installations. See the Operation section of this guide
for more details.
The converter comes equipped with a bank of DIP switches and
set of jumpers for setting configuration.

The following steps are used to configure the Media Converter.

1. Set the DIP switch settings (optional).

2. Insert the SFP modules (purchased separately) into the
transceiver ports.

3. Connect the power cord strain relief clip (optional) and
connect and apply power.

DIP Switch Settings

The DIP switches are accessible through the opening in the side
of the enclosure.

Link Mode (Switch 1)

Switch Position Mode

Up (default) Smart Link Pass-Through Mode
Down Standard Mode

Smart Link Pass-Through: In this mode, the fiber link state on
one connection is directly reflected through the Media Converter to
the other fiber connection. Since this media converter is protocol
independent, it monitors the Signal Detect indicator from the SFP

4

and reflects this on the TX port of the other SFP by turning off the
transmitter. When the signal (Link) gets restored and Signal
Detector becomes active the affected transmitter gets re-enabled.

Standard Mode: In Standard Mode the media converter will
monitor the fiber link in the same manner. If Signal Detect goes
down the media converter will output a 25MHz signal on the TX
port of the other SFP.

Fiber Fault Alert (Switch 2)

Switch Position Mode
Up (default) Enabled
Down Disabled

Enabled: If the media converter detects a loss of fiber signal on its
fiber receiver, it will disable its fiber transmitter on the same SFP.
This, in effect, notifies the fiber link partner that an error condition
exists on the fiber connection.

Disabled: The Protocol Transparent Media Converter will not
monitor for Fiber Fault.

Rate Select (Switch 3)

Switch Position Mode
Up (default) High Speed
Down Low Speed

High Speed – When a multi-rated SFP is inserted, it is enabled for
its higher speed of operation.

Slow Speed – When a multi-rated SFP is inserted, it is enabled
for its slower speed of operation.

Attaching the Power Cord Strain Relief
Clip

For extra power cable strain relief, attach the strain clip to the side
of the unit, then thread the power cable through the clip in either
one or two loops.

Operation

Powering up the Perle Media Converter

1. Connect the Perle supplied power adapter to the media
converter.

2. Turn on the power at the source.

3. Check that the PWR LED light is lit.

Terminal Block Connector

1. Ensure the Power Source is off prior to connection.

2. Strip insulator sheathing from both wires 5mm (3/16th
inch) to expose the copper conductor wire.

3. Loosen the terminal block screws and connect Positive (+)
wire to the left terminal. Connect the Negative (-) wire to
the right terminal. Tighten Terminal screws (0.22Nm-

0.25Nm torque).

4. Turn on power source.

5. Check that the PWR LED light is lit

Status LED

There are three status LEDs located on the front of the unit.
