OCTA40x0TX&RX (MW07SP2)
1. General description
OCTA 40x0 (4010 for multimode and 4050 for single-
mode) digital optical multiplexer/demultiplexer systems
can transmit eight unidirectional, independent composite
video signals via one optical fiber. The video input
signals are sampled and digitized with 10-bit accuracy.
The OCTA 40x0 TX unit receives input via the eight
BNC connectors. It then converts and combines the eight
composite video channels into one serial digital data
stream. This, in turn, is converted into an optical signal.
The composite video channels are digitally clamped after
being AC coupled at the inputs. The digital clamp is
compatible with NTSC and PAL sync timing. The video
channels are not compatible with non-video (NTSC and
PAL) signals.
The OCTA 40x0 RX unit receives, converts and decodes
the incoming optical signal to recover the eight
individual composite video channels. The output is
disseminated via the eight BNC connectors.
Front panel status LEDs indicate DC power OK, video
signal presence, link synchronization (RX only).
OCTA 40x0 units are double single-width (14TE)
Eurocard-sized modules and should be used in
combination with MC 11 or similar power supply
cabinets.
Stand-alone models (/SA option, see supplementary
/SA-2 manual) need separate 12 VDC power supplies. A
Siqura PSA 12 DC-25 would be suitable.

3. Installation
1. Plug the modules into the appropriate power supply
cabinet (or hook up the /SA-2 models to corresponding
power supplies) and connect suitable video and optical
fiber equipment using appropriate cabling.
CLEAN THE OPTICAL FIBER CONNECTORS
PRIOR TO INSERTION INTO THE OPTICAL PORT.
Equipment and cabling should be installed and earthed
such that protection is provided against lightning and
similar influences.
2. Upon powering up, the green DC LEDs and SYNC
LED (on the RX) should glow green, indicating link
integrity. If the RX SYNC LED shines red, there is no
link synchronization. If SYNC problems occur after
powering up, please first check the received optical
power arriving at the RX unit using an optical power
meter.
3. With the optical link in good order, connecting a video
signal should make the corresponding channel's TX and
RX NV (no video) LEDs go out.
An RX NV LED still lit would indicate that no
decodable video signal is arriving through the associated
channel.
4. Care and maintenance
For reliable operation of OCTA 40x0 modules, please
observe the following precautions:
- Prevent dust from collecting on the equipment
- Protect the equipment against moisture
- Maintain sufficient free space around the equipment for
cooling.

6. Safety, EMC, ESD
General
The safety information contained in this section, and on other
pages of this manual, must be observed whenever this unit is
operated, serviced, or repaired. Failure to comply with any
precaution, warning, or instruction noted in the manual is in
violation of the standards of design, manufacture, and intended use
of the unit.
Installation, adjustment, maintenance and repair of this equipment
are to be performed by trained personnel aware of the hazards
involved. For correct and safe use of the equipment and in order to
keep the equipment in a safe condition, it is essential that both
operating and servicing personnel follow standard safety procedures
in addition to the safety precautions and warnings specified in this
manual, and that this unit be installed in locations accessible to
trained service personnel only.
Siqura assumes no liability for the customer’s failure to comply
with any of these safety requirements.
UL/IEC/EN 60950-1: General safety requirements
The equipment described in this manual has been designed and
tested according to the UL/IEC/EN 60950-1 safety
requirements.
If there is any doubt regarding the safety of the equipment, do not
put it into operation. This might be the case when the equipment
shows physical damage or is stressed beyond tolerable limits (e.g.
during storage and transportation).
Before opening the equipment, disconnect it from all power sources.
The equipment must be powered by a SELV*) power supply.
When this unit is operated in extremely elevated temperature
conditions, it is possible for internal and external metal surfaces to
become extremely hot.
Optical safety
This optical equipment contains Class 1M lasers or LEDs and
has been designed and tested to meet IEC 60825-1:1993+A1+A2
and IEC 60825-2:2004 safety class 1M requirements.
Optical equipment presents potential hazards to testing and
servicing personnel owing to high levels of optical radiation. When
using magnifying optical instruments, avoid looking directly into
the output of an operating transmitter or into the end of a fiber
connected to an operating transmitter, or there will be a risk of
permanent eye damage.Precautions should be taken to prevent
exposure to optical radiation when the unit is removed from its
enclosure or when the fiber is disconnected from the unit. The
optical radiation is invisible to the eye.
Use of controls or adjustments or procedures other than those
specified herein may result in hazardous radiation exposure.
The installer is responsible for ensuring that the label depicted
below (background: yellow; border and text: black) is present in
the restricted locations where this equipment is installed.
The locations of all optical connections are listed in the Indications
and Connectors section of this manual.
Optical outputs and wavelengths are listed in the Technical
Specifications section of this manual.
Hazard Level 1M

4
EMC
The equipment has been tested and found to meet the CE-
regulations relating to EMC, and complies with the limits for a
Class B device, pursuant to Part 15 of the FCC rules. These
limits are designed to provide reasonable protection against
interference to radio communications in any installation. The
equipment generates, uses and can radiate radio frequency energy;
improper use or special circumstances may cause interference to
other equipment or a performance decrease due to interference
radiated by other equipment. In such cases, the user will have to
take appropriate measures to reduce such interactions between this
and other equipment.
Any interruption of the shielding inside or outside the equipment
could cause the equipment to be more prone to fail EMC
requirements.
Non-video signal lines must use appropriate shielded CAT5
cabling (S-FTP), or at least an equivalent.
If system components, such as cabling (e.g. coaxial cable,
data/audio/cc wiring) and/or the units, are used outdoors, ensure
that all electrically connected components are carefully earthed
and protected against surges (high voltage transients caused by
switching or lightning).
ESD
Electrostatic discharge (ESD) can damage or destroy electronic
components. Proper precautions should be taken against ESD
when opening the equipment.
*) SELV: conforming to IEC 60950-1, <60VDC output, output voltage
galvanically isolated from mains. All power supplies or power supply
cabinets available from Siqura comply with these SELV requirements.
7. Product Disposal
The unit contains valuable materials which qualify
for recycling. In the interest of protecting the
natural environment, properly recycling the unit at
the end of its service life is imperative.
