Introduction

1 INTRODUCTION

1.1 About the products

The Black Box range of Fibre Converters tabulated below provide a simple economic

way of converting from one type of transmission medium to another. Examples include:

Electrical signals on copper to optical signals on fibre, and vice-versa.

Single-mode optical fibre to multimode and vice-versa.

Model Customer Interface Line Interface

MTU9230 E3/DS-3 G.703 via BNC 75 ohm Dual SC Multi-mode fibre

MTU9240 E3/DS-3 G.703 via BNC 75 ohm Dual SC Single-mode short haul fibre

Introduction

The MTU9230/MTU9240 have been designed to be plug and go, conforming to appropriate

standards, physically very compact, and rack mountable in sets of 2 using a dual face plate,

or 18 units in a rack mount kit for large installations. FC units often enable substantial

savings to be made in cable costs by utilising the cheapest effective cable type without

incurring the costs of additional router or switch interfaces.

We are continually developing new models, so if the interface combination required

is not listed in this guide, please contact us.

1.2 Safety

Where electrical signal cabling is connected to the units, do not connect to cabling which

would be required by BS6701 to be equipped with over-voltage protection. Electrical signal

ports should only be connected to SELV ports on other equipment in accordance with

EN60950 clause 2.3.

1.3 Electromagnetic Compatibility

In order to ensure EMC compliance all electrical signal and data cables and connectors must

use a screened connector shell with a screened cable. The cable screen must be terminated

to the screened connector shell and not connected to any pins of the connector. Failure to

use the correct connector may compromise EMC compliance.

1.4 EN55022 Declaration

FC units are a Class A product. In a domestic environment it may cause radio interference

in which case the user may be required to take adequate measures.

1.5 FCC Declaration

This equipment has been tested and found to comply with the limits for a Class A digital

device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference when the equipment is operated in a

commercial environment. This equipment generates, uses, and can radiate radio frequency

energy and, if not installed and used in accordance with the instruction manual, may cause

harmful interference to radio communications. Operation of this equipment in a residential

area is likely to cause harmful interference in which case the user will be required to correct

the interference at its own expense.

1.6 WEEE Directive

Both units are covered by Directive 2002/96/EC (OJ:L37/24/2003) on waste electrical and

electronic equipment (The WEEE Directive). Units must therefore not be disposed of in

a standard landfill.

Introduction

1.7 Power Supply

Both units are powered by an internal mains-fed power supply. The mains input voltage is

100-250VAC, 50/400Hz. An alternative -48VDC power supply is available on all units as a

custom order item. The power consumption of each model in the range is shown below,

together with the current consumption over the operating voltage ranges.

An alternative -48VDC or -24 VDC power supply is available on most units as a custom order

item.

The supply definition of the -48VDC supply is minus 36 to minus 72 VDC, 200-100 mA. DC

power is supplied via a 3 pin Buccaneer socket fitted to the rear panel.

The supply definition of the -24VDC supply is minus 12 to minus 36 VDC, 700-125 mA. DC

power is supplied via a 2 pin Buccaneer socket fitted to the rear panel. The surrounding label

is cloured blue for the -12V/-24 option.

A Buccaneer plug is supplied with the unit for customer’s own wiring. The connections are

labelled on the rear panel of the unit as shown in the schematics below.

The units must be connected to safety earth for correct operation. The FC power supply

should be connected to a supply socket that is physically located close to the unit and is

easily accessible.

The power consumption of the units is shown below, together with the current

consumption over the operating voltage ranges.

Introduction

Safety Notes: Excessive voltages are present inside the unit. There are no user serviceable

parts inside the unit, and the cover should not be removed by unqualified personnel. The unit

must not be exposed to damp or condensing conditions.

Unpacking & Installation Procedure

2 UNPACKING & INSTALLATION PROCEDURE

2. 1 Unpack and inspect the equipment.

The carton should contain a single unit and for UK models, a power cable.

If there is any visible damage, do not attempt to connect the device. Contact your Supplier

or Black Box Technical support for advice and assistance.

2. 2 Optional rackmounting procedure

Rackmounting kit Part No MTU9000M-RACK may be used to mount two FC units side by

side in a 19” rack. First remove the two rear panel screws securing each unit’s lid. Fasten the

2 units to the rack mount adaptor plate using the screws that you have removed, as shown in

the illustrations below.

Then secure the rack mounting plate complete with the two units to the 19” rack using

the locating holes at the ends of the adaptor plate. The recessed twin unit rack will accept

either AC or DC FC models.

Figure 2.2 Twin unit rack mounting

If you wish to use the optional 18 unit mounting rack, instructions are provided with the rack,

part number MTU9000M-18RACK-AC (AC Mains) or MTU9000M-18RACK-DC (DC Supply).

Unpacking & Installation Procedure

2. 3 Power up the units

The unit requires 100-250 VAC, 50-60 Hz AC supply, drawing less than 50mA when

operating.

Alternatively, a -48VDC power supply is available as another option for all models.

The DC power options are -36 to -72 VDC (-48VDC), or -12 to -36 VDC (-24VDC), using a

Buccaneer type connector. See Section1 for further details on power consumption.

Plug a power cable into the back of the unit and switch on. Check that the Alarm LED on

the rear panel is illuminated red or green, flashing or steady. If the LED is off, power is not

being supplied to the unit.

2. 4 Connect the Customer and Network ports.

When all the ports are connected, the Alarm LED should give a steady Green display. Set-

up information for both models is contained in each section of this manual.

2. 5 Optionally connect the alarm relay

Many units offer an Alarm relay to provide an external warning of problems which may

arise. The interface is presented on an RJ45 connector, and offers both normally open and

normally closed contacts. Maximum contact rating is 1.5 Amp at 125 VDC. Normal is the

powered up, non-alarmed state. The connections are shown in the table below:

5.1.1 Power connector

AC mains power is supplied via an IEC connector. The units have an integral power supply

operating over the range 100-250 VAC. It draws less than 50mA of current when operating.

Alternative -48 VDC and -24VDC power supplies are available. See Section 1 of this manual

for further details of this option and consumption data.

The units must be connected to safety earth for correct operation. The MTU9230 power

supply should be connected to a supply socket that is physically located close to the unit and

is easily accessible.

5.1.2 External alarm relay

Both models offer an Alarm relay to provide an external warning of problems which may

arise. The interface is presented on an RJ45 connector, and offers both normally open and

normally closed contacts. Maximum contact rating is 1.5 Amp at 125 VDC. Normal is the

powered up, non-alarmed state. The connections are shown in the table below:

Cable lengths should be restricted to those defined below:

Figure 5.5 Cable lengths

Note: The total maximum attenuation of each of the cables attached to the BNC (network)
