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 out of your Fibre Optic Link.

Electrical Safety

The ViaLiteHD chassis is a Safety Class 1 product (having metal case directly connected to earth via the power

supply cable).

When operating the equipment note the following precautions:

Hazardous voltages exist within the equipment. There are no user serviceable parts inside; the covers should

only be removed by a qualified technician.

There are no user replaceable fuses in the chassis mounted equipment. Replacement should only be carried out

by a ViaLite Communications 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.

ESD Precautions The ViaLiteHD support modules are equipped with high frequency active electronics, without the correct handing they

will be susceptible to damage.

Precautions for handling electro-static sensitive devices should be observed when handling all ViaLiteHD 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”

Optical Safety The ViaLiteHD serial digital and Ethernet devices contain optical sources (usually laser diodes) operating at nominal

wavelengths of 1270nm to 1610nm.

These devices are rated as EN60825-1:2007 as CLASS 1 radiation emitting devices. A class 1 laser is safe under

all conditions of normal use.

When operating the equipment note the following precautions:

Never look into the end of an optical fibre directly or by reflection either with the naked eye or through an optical

instrument.

Never leave equipment with radiating bare fibres –always cap the connectors.

Do not remove equipment external covers when operating.

1 Introduction

The 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. ViaLiteHD is a product brand manufactured by Pulse Power and Measurement

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

The ViaLiteHD system offers a family of support modules that provide range of functions that can be used stand alone or with its RF Fibre

Optic Links (FOLs).

This handbook covers the following ViaLiteHD RF support modules:

Amplifier module

oHRA

Serial Digital modem

oHRB

Splitter module

oHRD

RF switch module

oHRS

Gigabit Ethernet optical link module

oHRE

LNB power supply module

oHRP

For complete information and product familiarisation, this handbook should be read in conjunction with all other relevant handbooks for your

ViaLiteHD system.

ViaLiteHD and ViaLite Classic compatibility1.1

The RF interfaces of most ViaLiteHD and ViaLite Classic are compatible. However the physical size, mounting systems and control of the

modules are different, so it will not be possible to fit ViaLiteHD module in a ViaLite Classic chassis or housing and vice versa. However it is

possible for chassis of different types to interwork and be used to expand existing systems. Listed below is a brief summary of inter family

compatibility.

Amplifier module Compatible RF interfaces

Splitter module Compatible RF interfaces

RF switch module Compatible RF interfaces, control interface not compatible 1

1It would be possible under some configurations, to extend the RF switches open collector input control interface to another chassis.

This would require the construction of a custom wire loom. Contact Vialite Communication or your local agent for more details.

HRS-HB-9 SUPPORT MODULE HANDBOOK.DOCX

2 Setting up and understanding the modules

This section describes the connection of your RF support modules and the operation with other system elements.

Please read fully all relevant documents for information on installing your ViaLiteHD equipment before commissioning your RF fibre optic link

system.

Module operation2.1

5HP blindmate plug-in modules2.1.1

All ViaLiteHD plug-in modules are hot-swappable, so it is not necessary to power-down the chassis before inserting a module. All blind mate

optical connectors are provided with spring loaded covers that will protect the optics of any inserted modules. As there is no cover on the

opposite side, mating cables should not be installed until the slot modules are present.

To install a blind mate module and matching interface plate

Firstly inspect the rear blindmating plate [1], ensure that the connector barrels are fitted into all RF connectors and are centrally aligned.

Remove protective covers from the inside face of the optical connector if fitted.

Ensure that the rear plate is free of any dust and contamination, if necessary clean with filtered compressed air.

Screw the blindmating plate into the appropriate slot at the rear of the chassis, using the supplied screws and a “Pozidriv Number 1”

screwdriver [2]

Push the release button of the module handle down and simultaneously pull the top of the handle towards you.

Align the module upright and perpendicular to the front face of the chassis so that the PCB slides into the “crow’s feet” card guides top

and bottom. [3]

Gently push the module down its guide, applying pressure via the handle (without locking it), you may also apply pressure between the

LED and test connector [4].

As the module is fully mated the top of the handle should snap back and lock in position.

The pawls of the handle should be fully engaged in the matching slots.

If power is applied to the chassis the module power LED should light as soon as the module is fully inserted.

Connect any interface cables to the blind mate plate, at the rear of the chassis.

[1] [2] [3] [4]

To remove a blind mate module

Push the release button of the module handle down and simultaneously pull the top of the handle towards you.

Apply pressure via the handle and gently withdraw the module from the chassis.

Check that the RF mating barrel is retained by the chassis Blindmating plate

All cables with be retained by the chassis.

HRS-HB-9 SUPPORT MODULE HANDBOOK.DOCX

5HP standard plug-in modules2.1.2

All ViaLiteHD plug-in modules are hot-swappable, so it is not necessary to power-down the chassis before inserting a module. All standard

optical connectors are retained by the module, so it will be necessary to either disconnect any cables or have a sufficiently long service loop

when removing modules.

To install a 5HP standard module and matching interface plate

The protective covers on the connectors may be left in place.

Push the release button of the module handle down and simultaneously pull the top of the handle towards you.

Align the module upright and perpendicular to the front face of the chassis so that the PCB slides into the “crow’s feet” card guides top

and bottom.

Gently push the module down its guide, applying pressure via the handle, you may also apply pressure between the LED and test

connector.

As the module is fully mated the top of the handle should snap back and lock in position.

The pawls of the handle should be fully engaged in the matching slots.

If power is applied to the chassis the module power LED should light as soon as the module is fully inserted

Remove protective covers and connect any interface cables

To remove a 5HP Standard module

Disconnect any cables if necessary

Push the release button of the module handle down and simultaneously pull the top of the handle forwards.

Apply pressure via the handle and gently withdraw the module from the chassis.

HRS-HB-9 SUPPORT MODULE HANDBOOK.DOCX

Blue Link modules2.1.3

The Blue Link module is fully enclosed and built with connectorised interfaces with electromagnetic shielding. This allows system integrators

and equipment manufacturers an easy route to build RF/optical interfaces into their own equipment. The small form factor and integrated

design should allow the module to be easily integrated into end user equipment.

Yellow Link modules2.1.4

The Yellow Link module has an edge connector for DC and alarm connections, an integrated RF shield, and a very small overall form factor.

This allows system integrators and equipment manufacturers to very simply integrate this on a motherboard giving an easy route to build

RF/optical interfaces into their own design. The low volume of this module allows it to easily be fitted into existing mechanical housings.

Using the support module2.2

Connecting the module2.2.1

Connect the transmitter module to the power source, cross-site fibre optic cable and RF signal as described in section 2.1. The RF input

signal applied to the signal connector should be within the maximum and minimum signal levels given in the technical specifications in

section 6.

Front panel Indicators, plug in modules2.2.2

Each plug-in module has three front panel LEDs for indication of the state of the module. The following table shows the operation of the front

panel LEDs of the amplifier.

Module summary alarm2.2.3

Each module has a single summary alarm, which registers the status of the module. Activation of this alarm registers an internal fault and the

module should be replaced with a spare and returned to your local ViaLite Communications representative. The alarm state should be

accompanied by a fault status on one of the front panel Status LEDs.

The summary alarm is indicated by use of open drain logic. The alarm logic is OPEN when in an ALARM state and SHORT when in a

NORMAL (non alarm) state. The module will remain in an ALARM state until the ALARM condition is cleared, there is no latching.

Connecting to the summary alarm2.2.4

The alarm output pin should be connected to a suitable current source (a positive voltage via a 10kohm pull-up resistor is adequate). When

the module is in a working (non-alarm) state, the alarm output pin is short circuited to ground by the module. If the module enters an alarm

state, the alarm pin is released to a high impedance state and current is no longer drawn from the constant current source. In the case of a

positive voltage and pull-up resistor, the voltage on the alarm output pin will rise to indicate the alarm state. It follows that, if a module is

removed from the chassis, the alarm will be raised for that module position.

The capability of the open collector is dependent on the module that provides it.

The typical capability of the Open Collector/Drain is 50mA maximum current sink and 15V maximum voltage (Vext)

RF connectors2.2.6

ViaLiteHD products are fitted with a range of standard RF connectors. The RF modules are all fitted with FEMALE connectors. When

connecting the modules ensure that you have both the correct type and impedance of connector. Listed below are the connector types

available.

Front panel test connectors, plug in modules only

BNC 50 ohms bayonet

BNC 75 ohms bayonet

Rear Input/Output connectors, plug in modules only

SMA 50 ohms screw on

BNC 75 ohms bayonet

F-Type 75 ohms screw on

Not all connector types are available on all types of module. If you are unsure of the connector type your module is fitted with this can be

determined from the part number (see section 5). Blind mating modules are fitted with a floating RF connector, mating between the plug in

module and the chassis rear plate. This is a purely internal interface and should not be connected by any means other than via the supplied

chassis interface.

Warning! Use of incorrect impedance connectors may also cause intermittent connections and in extreme cases result in

physical damage to the connector.

Warning! Use of incorrect impedance connector will result in mismatch increasing the system loss and reducing flatness.

Warning! Use of incorrect impedance cable will result in mismatch increasing the system loss and reducing flatness.

RF and optical rear input and output ports2.2.7

All modules are fitted with one, two or three rear RF ports. All new Blindmate modules are supplied with an appropriate chassis interface

plate. LEFT and RIGHT refer to connection to adjacent module, referenced to the front view.
