Introduction to this Operation Manual
This manual covers the operation and use of the modules described below.
WARNING…
THE FRONT PANEL OF THE UNIT MUST NOT BE
OPENED BY THE OPERATOR. ACCESS IS ONLY
PERMITTED TO FULLY QUALIFIED
INSTALLATION ENGINEERS.
System HD Modules must only be installed and/or replaced by qualified service personnel, with reference to
the System HD Installation guide. Refer all installation and servicing to qualified personnel only.
All laser transmitters used in this product are Class
1 in accordance
with EN60825-1 as well as 21CFR 1040.10 and
1040.11
1. Laser light can be damaging to the eyes.
Optical fibres and Uniters should be handled with
great care.
2. System HD Modules which incorporate Fibre
Optic elements, are designed for use with Class 1
laser systems only. Ensure that all inputs do NOT
exceed Class 1 as doing so will impair the safety
of the system and may result in damage to the
equipment.
3. Active fibres should not be handled unless
their source can be positively identified as not
exceeding Class 1 limits.

Module Description
The Optical HD-SDI Transceiver can convert an
electrical HD-SDI bitstream to an optical HD-SDI
bitstream while simultaneously converting a
separate optical HD-SDI bitstream into an electrical
HD-SDI bitstream. With the ‘standard’ interface
card fitted (rear view shown above), the optical
input path provides four identical electrical HD-SDI
outputs and the electrical HD-SDI input channel
can provide up to four identical optical HD-SDI
outputs.
The electrical high definition serial digital (HD-SDI)
bitstream interfaces are via 75ΩBNC connectors
on the backpanel of the rear interface card. The
optical outputs are via the SMPTE292M
recommended SC/PC singlemode fibre optic
connectors. The SC/PC connector is robust and
easy to use, a simple snap-fit enables a reliable
connection to be made in a matter of seconds.
Connected to the single output of the laser
transmitter is an optional passive optical splitting

SHDFTRX OPERATION
SHDFTRX Version 1 Issue 5 180203 5
device providing up to four identical optical outputs.
The options for this split are either a four way
splitter, a two way splitter, or a single output.
Selection between these options depends on the
rear interface fitted and does not affect the main
board part of the module. Even in the case of the
four way splitter the optical power available from
each of these outputs is sufficient to transmit a HD-
SDI signal over distances greater than 20km.
A re-clocked active loop-through of the electrical
HD-SDI bitstream input is available from a BNC
connector for monitoring purposes. Three optical
power options, including two wavelength variants
are available as laser options. The different
wavelengths are provided for Wavelength Division
Multiplexing (WDM) options on this board.
The receiver section of the transceiver main board
accepts a single optical high definition serial digital
(HD-SDI) bitstream input via a SC/PC singlemode
fibre optic connector. The re-clocked electrical HD-
SDI signal output from the receiver is split to
provide four identical coaxial HD-SDI outputs for
the user at the backpanel of the interface card.
When used in conjunction with a System HD
optical transmitter (and depending on the fibre
interconnect used) the sensitivity of the optical
receiver is sufficient to recover a signal transmitted
from up to 20km away. The receiver device is
capable of recovering wavelengths between 1.2-
1.6µm making it suitable for wavelength division
multiplexing (WDM) applications.
By using the ‘WDM’ interface card, the transceiver
card allows simultaneous transmission/reception of
two different wavelengths, 1.3µm and 1.5µm.
LEDs mounted at the front of the main board allow
monitoring of the receiver performance. More
detailed performance information can be obtained
via the RollCall interface.
The ‘standard’ rear interface card option offers four
optical outputs for the transmitter section of the
transceiver. However, depending on the
application, two or single output options are also
available as well as a ‘WDM’ interface card.
It is recommended that the System HD Order Code
of the board and interface card combination is
recorded in this manual on the next page using the
table on this page for your own reference.
This will allow easy identification of the laser option
chosen and the type of interface card selected
when referring to this manual at a later date.

1. Laser light can be damaging to the eyes.
Optical fibres and Uniters should be
handled with great care.
2. System HD Modules which incorporate
Fibre Optic elements, are designed for use
with Class 1 laser systems only. Ensure
that all inputs do NOT exceed Class 1 as
doing so will impair the safety of the
system and may result in damage to the
equipment.
3. Active fibres should not be handled unless
their source can be positively identified as
not exceeding Class 1 limits.
Notes…
1. Optical uniters have plastic covers to prevent
the ingress of dust. These covers should only
be removed when connecting optical fibres. A
uniter should never be left open without a
cover or a fibre connector
2. The ends of optical fibres should be cleaned
with a liquid fibre cleaner, using a cotton bud,
to ensure that there is no dust present, before
they are plugged in (the uniter is polarised).
3. Observe the warning about not viewing live
optical sources.

Standard Transmitter Outputs
Optical HD-SDI Output – Quad Output Option
Used On : SHDFTRX0WQ4
The high definition serial digital optical outputs are
provided via a pair of dual SC/PC single mode
panel mounted uniters. The overall connection is
labelled as H1 on the rear panel as shown
opposite. The four optical outputs are denoted as
1, 2, 3, and 4 and arranged as shown in the
diagram. All four outputs produce almost identical
levels of optical power and identical digital
bitstreams. These are single optical wavelength
outputs.
Do not remove the covers from the uniters until a
fibre connection is ready to be inserted.
Optical HD-SDI Output – Dual Output Option
Used On : SHDFTRX0WQ2
The high definition serial digital optical outputs are
provided via a dual PC/SC single mode panel
mounted uniter set. The overall connection is
labelled as H1 on the rear panel as shown
opposite. The two optical outputs are denoted as 1,
and 2. The rear label mentions connections 3, and
4 as well, but these are not present in this case.
The connectors are arranged as shown in the
diagram. Both outputs produce almost identical
levels of optical power and identical digital
bitstreams. These are single optical wavelength
outputs.
Do not remove the covers from the uniters until a
fibre connection is ready to be inserted
Optical HD-SDI Output – Single Output Option
Used On : SHDFTRX0WQ0
The high definition serial digital optical output is
provided from one side of a dual SC/PC single
mode panel mounted uniter. The overall connection
is labelled as H1 on the rear panel as shown
opposite. The optical output is denoted as
connection 1. The rear label mentions 2, 3, and 4
as well but these are not present in this case. The
connector is arranged as shown in the diagram.
This is a single optical wavelength output.

Bias/EQ – The value in this field is a guide to
the strength of equalisation that is being
applied to the input signal for longer cable
runs. The lower the value, the less equalisation
is being employed. It is intended as a guide for
troubleshooting the system. It should be noted
that when an equalisation of 100% is shown, it
doesn’t necessarily mean that the maximum
input cable length has been reached. As soon
as CRC errors are being reported then the
input cable length should be decreased until an
error free signal can be received.
Laser Case Temperature / Bias (Degrees °C) –
The case temperature is an indication of how
much Laser Drive Strength is being applied i.e.
Laser Bias current. As the laser becomes
older, the drive strength will be increased
which will therefore cause its case temperature
to rise.
Received Laser Power (dBm) – This is the amount
of Laser power being received. It indicates how
much attenuation has been applied to the signal.
