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 RF Fibre Optic Link is 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 RF Fibre Optic Transmitters 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.

The Blue2’s compact design means it can be used in existing customer equipment or easily fitted
in smaller spaces, such as ship radomes/below-deck control rooms where space can be
restricted. In addition to maritime, the Blue2 Link is suitable for use in the Broadcast, GPS or
regular Satcom markets.
1.4 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 0 for fibre optic cable
handling details.

2 Setting up and understanding the fibre optic link
This section describes the connections between your RF fibre optic transmitter (electrical –optical
converter) and receiver (optical - electrical converter) modules, and the operation of both modules in a
system.
Please read fully all relevant documents for information on installing your ViaLiteHD equipment
before commissioning your RF fibre optic link system.
2.1.1 RF connectors
ViaLiteHD Blue2 Link is fitted with 50 Ohm female SMA connectors.
The SMA connector is a semi-precision sub-miniature RF and microwave connector and to maintain
performance up to 8GHz, ensure that when not in use, the supplied RF connector dust caps are fitted.
If any dust or dirt is visible within the connector body, cleaning with compressed air before mating is
advised.
When attaching cables to these RF connectors, a torque wrench should be used to guarantee
tightening to 1.0 Nm.
2.1.2 Blue2 Link Module
The Blue2 Link is an RF over fibre module available for both the transmitter and receiver. The 15-way
D-type connector provides connectivity for the Tx or Rx alarms, I2C setup using the ViaLiteHD
Programming Kit(HRx-HD-DEV103).

2.2 Fibre optic cable & connectors
All ViaLiteHD RF modules use single-mode (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”
2.2.1 Connecting and disconnecting
Before connecting optical fibres to the module or to each other, ensure that the mating connectors are
clean (see below).
2.2.2 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.
Details can also be found on the CD supplied with your equipment.
2.2.3 Cleaning optical connectors, high levels of contamination
If there are performance issues that are not resolved by basic cleaning, 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 Isopropyl 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.
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.

VIALITEHD-BLUE2-LINK-HANDBOOK-HRX-XX-8X-35-XXXXX
10
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.
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.
Warning!
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.
2.2.4 FC/APC Connectors
To connect FC/APC optical connectors follow these steps:
Remove the dust caps and align the white ceramic centre ferrule on the cable connector with the
mating receptacle.
There is a key (lug) on the side of the ferrule, which must match the keyway (gap) in the receptacle
shroud.
When they are aligned, gently push the plug home.
Finger tighten the knurled collet nut onto the threaded receptacle.
To disconnect follow these steps:
Using fingers fully unscrew the knurled collet nut, gently withdraw the connector.
Replace the dust caps on both the receptacle and the cable plug.
Warning!
It is possible to tighten the knurled collet without aligning the lug and gap. This
will result in poor light transmission. Check that the lug and gap are aligned
before tightening the knurled collet

VIALITEHD-BLUE2-LINK-HANDBOOK-HRX-XX-8X-35-XXXXX

2.2.5 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 receptacles.
2.2.6 E2000/APC Connectors
All ViaLiteHD E2000 connectorised modules use E2000/APC. Clean the plug before inserting.
To connect E2000/APC optical connectors:-
Gently push the plug-into the E2000/APC adapter.
The cover will automatically disengage.
Push until a click is heard and the connector locks.
To disconnect:-
To disconnect, depress the lever at the rear of the connector and withdraw the connector.
The protective cover automatically engages when removed.
Only connect E2000/APC cable to E2000/APC adaptors.
2.2.7 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. Systems using longer wavelength (i.e.
1550nm) are less tolerant to small bend radii.
The minimum bend radius of standard SMF28 fibre optic cable fitted to ViaLiteHD modules is 50mm.
MBR specifications for ViaLite Communications supplied fibre optic cables are given in the ViaLite
Classic and ViaLiteHD System Handbooks Lxx-HB and Hxx-HB respectively.

VIALITEHD-BLUE2-LINK-HANDBOOK-HRX-XX-8X-35-XXXXX

2.3 Using the RF link module
2.3.1 Connecting the module
Connect the transmitter module to the power source, cross-site fibre optic cable and RF signals. The
RF input signal applied to the signal connector should be within the maximum and minimum signal
levels given in the datasheet.
2.3.2 LED indicator, purple modules
These modules are fitted with a single LED for indication of the state of the module.
2.4 Module Interface ratings
2.4.1 Susceptibility to DC pulses from ViaLiteHD receivers
All receiver modules will create a 1-2Vpeak DC transient from the RF output at start up into a 50Ω
load (approximately 5V into a 1MΩ load). This may cause failure in some very sensitive spectrum
analysers or similar equipment. Please check before connecting your equipment. Contact ViaLite
Communications for more details.
2.4.2 Protection of ViaLiteHD equipment from DC pulses
All modules have AC coupled inputs and/or outputs and will be sensitive to large transients (>5V)
applied at the RF connector. This may result in permanent damage to the modules, particularly to low
frequency or wideband modules. DVB-T and L-Band HTS modules are designed to survive non
repetitive DC pulse of up to 36V. To increase protection, BUC feed option “B” can be specified for
GPS receiver modules to increases their robustness to DC pulses contact ViaLite Communications
for more details.

3 System integration
3.1 Link loss budget calculations
The link gain (transmitter RF input level to receiver RF output level) depends on the following factors:
Optical loss (due to connector insertion loss and optical fibre loss).
Transmitter gain setting.
Receiver gain setting.
The actual link gain can be determined as follows:
Link gain = Transmitter Gain + Receiver Gain –(2 x optical loss) [dB]
(Where optical loss = connector insertion losses + fibre losses)
3.2 Optical loss versus gain
The additional electrical insertion loss in dB resulting from optical losses is equal to 2 times that of the
optical loss in dB. This is due to the physics of the optical-to-electrical conversion process in the
receiver. For example, a 1dB increase in optical insertion loss will result in a 2dB decrease in RF
signal at the output of the optical receiver.
For single-mode fibre (e.g. SMF28), the optical loss at the 1310nm operating wavelength of the
ViaLiteHD link is 0.4dB/km. For 1550nm operating wavelength, the optical loss is 0.2dB/km.
This can increase if the fibre is under excessive tension, compression or is bent into a small radius.
For clean, undamaged single-mode connectors, optical insertion loss is typically 0.2dB per interface.
Note: The losses at the optical connections of the transmitter and receiver are allowed for during
manufacture of the module, and may be ignored during link gain calculations.
For short links (<250m) containing no additional optical connectors, and in which the fibre is not
subject to any strain, the optical path loss can be ignored.
3.3 Optical loss versus noise figure
As the optical loss increases there will be a corresponding increase in noise, the chart below shows
the approximate relationship of optical loss to noise figure increase for a standard L-Band HTS link.
Below are graphs that shows the change in noise figure of some popular link types.
Note: If you operate the ViaLiteHD modules in RLL AGC mode it is possible to mask optical loss
variations, but this is not always desirable.

3.4 Gain versus frequency response
The frequency response is not significantly affected by the gain setting of the attenuators used in
ViaLiteHD. These have a flat frequency response over the full operating range of the product.
Figures below are typical L-Band HTS modules responses.

3.5 P1dB versus transmitter gain
The input P1dB of the link is dependent on the transmitter gain. Increasing the transmitter gain will
decrease the link input P1dB..
