Crystal Vision Introduction
FTX HD User Manual R1.0 3 13/08/2007
1 Introduction
The FTX HD is a two-channel serial digital video optical transmitter that will accept both
High Definition and Standard Definition video.
The universal connection system allows a mixture of Crystal Vision modules in the frame.
The modules plug in the front and the rear connectors plug in the back. A removable front
panel reveals LED indication of input and PSU status when opened.
FTX HD two channel SDI optical transmitter
The range of Crystal Vision optical boards has been designed to work in conjunction with
the Indigo 4 and the Indigo 2 and Indigo 1 frames of issue 2 and above. The board may be
plugged into any of the PCB slots, the only proviso being where it needs to be placed
below a Standard Definition board. The rules governing frame configuration are
explained in the installation chapter.
The RM31 single slot rear connector provides two serial digital inputs and two optical
outputs with up to 24 modules in 4U of rack space.
Note: You can find the issue number of a frame inside at the front.
The Indigo frames have been designed to accept any selection of boards from our range of
Standard Definition, High Definition, audio, video and optical products. The high packing
density allows up to six modules in 1U, up to 12 modules in 2U and up to 24 modules in
4U.
The main features of the FTX HD are as follows:
•2 channel HD/SD serial digital optical transmitter SMPTE 292M/297M
compliant
•Handles pathological test pattern
•1310nm class 1 compliant two channel laser module
•LED SDI input presence indication

Crystal Vision Introduction
FTX HD User Manual R1.0 4 13/08/2007
•Indication of laser near end of life and shutdown
•Automatic and manual laser shutdown
•Single-mode fibre system
FTX HD
The two identical channels of the FTX HD optical transmitter are completely independent
of each other. Each channel consists of a serial digital input section, which equalises the
input signal for cable length, a driver module and laser diode. Both channels are under the
control of a CPU, which monitors and reports their status.
At the heart of the FTX HD is a two-channel state-of-the-art laser driver module
incorporating automatic power control, which gives the laser diode emitters a stable
performance throughout their lifetime. Safety circuitry within the laser module monitors
the operation of the laser driver and forces a shutdown should any critical parameters be
exceeded. Warning is also given once the laser is considered to have reached near to the
end of its expected lifetime. This warning is triggered after approximately 85% of its
expected lifetime has expired.

TX HD dual channel HD/SD o
p
tical transmitter
The FTX HD is designed to work into single-mode optical cable and is capable of
achieving distances in excess of 30km depending on cable quality and number of
connectors and splices. The FTX HD will also work into multi-mode optical cable in
some circumstances and distances of approximately 1km are achievable with a Standard
Definition video input. Distances of 200-300m may be achievable with a High Definition
video input but performance with multi-mode fibre is not guaranteed.
Note: Caution this product emits high intensity light. Suitable precautions must be
taken when servicing the rear of a frame containing this product due to the possible
damaging nature of high intensity light.

Crystal Vision Hardware installation
FTX HD User Manual R1.0 5 13/08/2007
2Hardware installation
The Crystal Vision optical boards have been designed to work in conjunction with the
Indigo 4 frames, or Indigo 1 and 2 frames of issue 2 or higher. All modules can be
plugged in and removed while the frame is powered without damage.
Note: You can find the issue number of a frame inside at the front.
Handling
Due to its fragile nature fibre optic equipment must be handled with care. Sharp blows or
snagging the fibre pigtails will fracture the internal glass filament and destroy its light
carrying ability. A degraded performance will also result if a build-up of dust and dirt film
on the connector ferrules is allowed to occur. It is strongly recommended that the supplied
dust caps are replaced whenever the transmitter card or rear modules are de-mounted for
any reason.
PCB connectors with the dust caps fitted
The RM31 rear module is fitted with dust caps on both sides of the optical connector. The
pair of dust caps that will be internal to the frame must be removed before the rear module
is fitted. The external pair can then be removed when the fibre tails are connected. It is
also recommended that dust caps should be re-fitted if the fibre tails are to be removed for
any length of time. Should the FTX HD be removed for any length of time it is
recommended that the rear module should also be removed and stored with the dust caps
in place.

2.1 Universal rear connectors
When using the RM31 single height rear connector, the 4U Indigo 4 frame will house up
to 24 modules and three power supplies, the 2U Indigo 2 frame will house up to 12
modules and dual power supplies, while the 1U Indigo 1 frame will house six modules
and a single or dual power supply. The 1U desktop box will not currently accept the
Crystal Vision optical modules.
The Indigo frames have hinged front panels giving access to the PSU and all modules.
The universal frame wiring system allows any of the interface modules to be fitted in (1)
all positions with the use of removable rear modules.
(1) Due to height restraints, there are restrictions when mixing optical modules with other Crystal Vision
modules.
Loading restrictions
The FTX HD can be loaded into any slot position of compatible frames but due to its
extra height it is not possible to place cards from the Crystal Vision Standard Definition
video or audio range directly above it in certain positions. HD cards do not share this
restriction.

Note: Function key LEDs are illuminated when active.
Channel Status
The FTX HD will display the presence of a Serial Digital input signal and whether that
particular channel laser is emitting light. The absence of SDI input is also indicated along
with a laser shutdown.
Note: There can be several reasons for the laser to shut down, apart from it being
manually disabled for maintenance purposes or through a lack of video input. An
automatic shutdown will result if the laser’s working parameters become out of
specification. For example, reaching the end of its working life or for a transitory
transgression of design limits. Once the laser been has shut down, as a safety feature it
will latch in this condition. If it is suspected that the shutdown has been the result of a
transitory condition this latched shutdown condition may be reversed by moving the
channel shutdown switch to down then up again.
Both channel A and Channel B are independent in operation of each other.
