Instrument Care and Safety Information

Please read the whole of this section before using your ViaLiteHD product. It contains important safety

information and will enable you to get the most from your Fibre Optic link.

Electrical Safety

The ViaLiteHD enclosure is a Safety Class 1 product (having metal chassis directly

connected to earth via the power cable).

When operating the equipment note the following precautions:

Hazardous voltages exist within the equipment.

There are no user serviceable modules inside.

There are replaceable fuses inside the casing. Replacement should only be carried out

by a PPM technician.

The chassis earth stud SHOULD be connected to the safety earth.

When using a 2 pin power supply cable the chassis earth stud MUST be connected to

the safety earth.

The ViaLiteHD Power Supply Modules do not have an isolating switch on the mains

voltage inlet. For this reason, the ViaLiteHD chassis MUST be installed within easy

reach of a clearly labelled dual pole mains isolation switch, which supplies the

equipment.

PSU modules are fused on the mains live feed only. A second fuse should be used for

the neutral connection where the polarity of the connectors can be reversed; rating

should match those given in section 2.13.

ESD Precautions Precautions for handling electro-static sensitive devices should be observed when

handling all ViaLite modules. Technicians should ensure that they use effective personal

grounding (i.e. ESD wrist strap etc.) when servicing the equipment. Any equipment or

tools used should be grounded to prevent static charge build-up. Good practice should be

observed at all times. For reference see relevant standards.

EN 61340-5-1, “Protection of Electronic Devices from Electrostatic Phenomena – General

Requirements”

OUTDOOR ENCLOSURE TYPE MINI HANDBOOK

1 Introduction

The Outdoor Enclosure type MINI (ODE-MINI), is a cost-effective weatherproof enclosure for ViaLiteHD

systems and associated hardware. It is intended to service the requirements of most GPS timing and satellite

communication systems though can be configured to suit a wide range of other applications.

The ODE-MINI system is comprised of the following key parts:

IP-65 rated external enclosure fitted with:

Dual power supplies (redundancy or power sharing)

Capacity for up to two ViaLiteHD OEM modules with front panel connections

Termination of input power cable (inside the supplied quick release latching connector)

Patch box for termination of optical cable (various quad fibre cable lengths available)

Connectorised RF inputs / outputs.

It has a wide range of optional accessories including:

Lightning suppressor(s)

Optical cable

Wall or pole mount fixings.

ViaLiteHD RF Fibre Optic Links (FOLs) are a family of fibre optically coupled link systems designed for the

transmission of RF analogue signals over long distances for the communications market.

ViaLite is a product brand manufactured by Pulse Power and Measurement Ltd (PPM).

ViaLite Communications is a division of Pulse Power and Measurement Ltd (PPM).

1.1 Typical deployment

A typical system operates as follows.

The ODE-MINI would house a set of FOL TX modules, in a remote outdoor location connected to antenna

equipment. Antenna electrical signals are input to the transmitter modules, which contain RF signal

conditioning and laser control circuitry. The modules modulate the intensity of a beam of light with the RF

signal for optical transport over a fibre optic cable.

The light travels through the optical fibres to corresponding receiver modules. The distance between

transmitter and receiver can range from 1 m to 100 km; distance in excess of 100 km can be achieved with

more complex optical transport systems, depending on the system specified.

The receiver module converts the modulated light back into an electrical signal, which is available at its

output.

1.2 ViaLiteHD compatibility

The RF and optical interfaces are compatible with all ViaLiteHD Blue modules.

Contact ViaLite Communications or your local ViaLite agent for more details.

1.3 Care of fibre optic connectors

When the fibre optic cables are not connected, it is essential that the cable and equipment connectors are

protected by the dust caps provided with the system. Failure to do so may result in damage to the fibre ends,

which are critical to the system performance. Please refer to section 1.4 for fibre optic cable handling details.

OUTDOOR ENCLOSURE TYPE MINI HANDBOOK

1.4 Fibre optic cable & connectors

Connector and cable types

All ViaLiteHD RF modules use singlemode (9µm/125µm) cable terminated in a range of optical connectors

detailed below. Cross-site fibre optic cables are available from ViaLite Communications as either standard

patch leads or heavy-duty multicore cables.

Warning!

Angle polished (APC) and standard (PC) connector must not be confused. The two

connector types are not interchangeable and mating one with the other will damage both the

cable and the module connectors.

The specification of optical connector is critical to the performance of the complete fibre optic

link. System performance can only be guaranteed with fibre optic cables and connectors

supplied by ViaLite Communications. When FC/APC connectors are specified they must

be “narrow key width”.

Connecting and disconnecting

Before connecting optical fibres to the module or to each other, ensure that the mating connectors are clean

(see below).

Cleaning optical connectors, cleaning before every use

Optical connectors MUST be cleaned before use, even where they have been protected with dust caps.

A large percentage of performance issues can be attributed to dirty fibres.

For more details please read the cleaning instruction which accompanies the connector cleaning kit.

Cleaning optical connectors, high levels of contamination

If there are performance issues that are not resolved by basic cleaning in section 1.4.3, then the following

procedure should be used. If the level of contamination is high it will be necessary to repeat this procedure.

Cleaning items required

Lint free fibre cleaning tissues and/or cleaning sticks (normal cosmetic tissues produce dust and are not

acceptable).

Reagent grade Iso Propyl Alcohol (IPA).

Air duster or filtered compressed air line.

Cable Connector Cleaning

Dampen a patch of cleaning tissue with IPA and clean all surfaces of the plug ferrule.

Using a dry cleaning tissue, dry the ferrule and clean the end face.

Using the air duster, blow away any residue from the end of the connector.

Peel the plastic cover from an unused “N”

cleaning pad.

Hold the connector between your thumb

and forefinger

Clean the connector using firm pressure by

swiping in a pendulum motion through each

segment of the “N” shape, following the

diagram

Do not swipe over the same space twice.

OUTDOOR ENCLOSURE TYPE MINI HANDBOOK

Module Female Receptacle Cleaning (only recommended if problems are being experienced)

Either use an optical cleaning stick or twist a cleaning tissue to form a stiff probe, moisten either with IPA.

Gently push the probe into the receptacle and twist around several times to dislodge any dirt.

Repeat the above process with a dry tissue.

Using the air duster, blow away any residue from the receptacle.

Important Notes

IPA is flammable. Follow appropriate precautions / local guidelines when handling and storing.

IPA can be harmful if spilt on skin. Use appropriate protection when handling.

It should only be necessary to clean the female receptacles on the modules if problems are being

experienced.

Never inspect an optical fibre or connector with the naked eye or an instrument unless you

are convinced that there is no optical radiation being emitted by the fibre. Remove all

power sources to all modules, and completely disconnect the optical fibres.

SC/APC Connectors

To connect SC/APC optical connectors follow these steps:

Remove the plug protective cover.

Align the connector keyway slot in the adaptor to the key of the plug.

Gently push the plug-into the adapter until a click is heard and the connector locks.

To disconnect follow these steps:

Grip the body of the plug and gently pull the plug from the adaptor, replace the protective cover.

Only connect SC/APC cable to SC/APC.

Minimum bend radius

Because optical fibre is made of glass, it is important not to subject it to excessive stress. For this reason,

each type of cable has a minimum bend radius (MBR) specification, beyond which the cable cannot be bent

without permanent damage occurring.

The minimum bend radius (MBR) of fibre optic cable fitted to ViaLite modules is 50mm. MBR specifications

for ViaLite Communications supplied fibre optic cables are given in the ViaLiteHD RF Link Handbook.

2 Setting up the ODE-MINI

This section describes the connections between your ODE-MINI and external systems and steps that must be

taken to set it up. Your ODE-MINI should be delivered preconfigured and ready, but will require connections

to external services. This will generally require that you take the following steps:

Mount the ODE-MINI and the patch box in the required locations

Terminate the fibre connections within the patch box

Terminate the RF connections at the ODE-MINI base plate

Terminate the input power at the ODE-MINI base plate.

2.1 ODE-MINI external features

The ODE-MINI is closed via four M4 screws; this can be torqued with a 4mm AF hexagonal key. The rear

provides fixing points for mounting the unit to either a wall mount plate or a pole mounting kit. The unit may

also be fitted with a solar shield; this is advisable for any application where there may be significant solar gain.

Humidity control/ventilator gland

The enclosure incorporates a side mounted vent that allows the air pressure inside the enclosure to equalise

with the external environment. Furthermore, it allows excess humidity to leave the enclosure whilst preventing

moisture from entering.

Upon installation and sealing of the enclosure, this vent facilitates a stable low pressure differential to ease

stress on the seals and a natural continual drying of the internal humidity for improved reliability of the

electronics.
