Safety Precautions
The following safety precautions should be observed before using this product.
This product is intended for use by qualified personnel who recognize shock
hazards and are familiar with safety precautions required to avoid possible
injury. Do not make module connections unless qualified to do so.
Before connecting this product to the power source, verify that the output
voltage is within the specifications of the product’s power supply.
Before removing or installing a board, make sure the main module is turned
off and disconnected from power source. Do not attempt to modify or repair
any circuit unless recommended by the manufacturer.
Protect the power cable from being walked on or pinched by items placed or
against them.
Always unplug the power cable at the plug, do not pull on the cord itself.
Do not block any ventilation openings or fans.
Do not look into the end of a fiber when it is plugged into a transceiver or
active fiber, especially when using a magnifying instrument, such as a fiber
microscope.
Handle optical fiber with extreme care. Glass fiber is subject to breakage if
mishandled.
Grounded ESD wrist straps must be worn and proper ESD safety precautions
observed when handling printed circuit boards.

1.0 Introduction
Focal's Model 903 is a video/data multiplexer and fiber optic transmission system designed for Remotely
Operated Vehicle (ROV) applications. The Model 903 uses Time Division Multiplexing (TDM) and Wavelength
Division Multiplexing (WDM) to provide high multiplexing density in a compact, low-power package. Typical
systems support 4-8 broadcast quality composite video channels, up to 64 digital channels, and additional
bidirectional optical channels for high-speed sonar, digital video, or 10/100/1000 Mbps Ethernet links.
The high density version of the Model 903 has been optimized for very high multiplexing density in an
extremely compact, low power package capable of delivering high quality video end-to-end. It supports up to
8 video channels of uncompressed, digitized composite video as well as up to 8 RS-232 channels and 8
plug-in modules, which may be selected from a range of modules including RS-232, RS-485/422/TTL, analog
sonar (MS900), hydrophones, Tritech sonar ARCNET and CAN Bus.
This user’s guide provides complete information on the design, configuration, installation and
operation of Model 903 High Density (HD) multiplexer systems. All 903-HD systems presented in this
document are based on the new FMB-X-2.5 and –X backplane boards. System specific information
can be found in the 903-8xxx-xx installation drawings provided with your system.
This manual and the appropriate reference documents should be reviewed prior to installation or
reconfiguration of the multiplexer.
Card or PCB assembly numbers are given in the titles of the corresponding sections of the manual.
 Card assembly numbers refer to a complete printed circuit board assembly (PCBA) plus front panel,
optics, and assembly hardware, and are in the 903-00XX-XX and 903-5XXX-XX series.
 PCBA numbers apply to populated boards alone, such as backplanes and AIB plug-in modules, and
are in the 903-02XX-XX series.

2.0 System Overview
This document contains information about 903 high density systems based on FMB-X-2.5 boards (fiber
multiplexer boards with optical link running at 2.5 Gbaud).
A high density multiplexer system consists of a Model 903-HD high density remote module (vehicle or ROV
end) and a standard Model 903 console module (surface or shipboard end). The console module is provided
completely packaged in a Eurocard rack integrated with a power supply and all necessary optical
components. (Eurocard PCB dimensions are 100 x 160 mm.) The remote module is provided as a complete
rack, including backplane, fan, and a data I/O box.
The high density remote modules can be provided in 12 HP or 16 HP racks depending on the number of
video and data channels required.
The standard console modules can be provided in 42 HP or 50 HP racks. Note that 4HP corresponds to a slot
width of 0.8 inches or roughly 20 mm.
2.1 Multiplexer Systems
There are two types of 903 high density systems that are covered by this document. One type is the
4VID system which includes 4 composite/analog video channels and the other type is the 8VID system
with 8 composite/analog video channels. The following table provides a summary of the signal types
supported by these systems.

2.3 System Expansion
The cards in the 4VID and 8VID systems may be changed to provide a different mix of signal types or
increase the number of serial channels.
Please contact the factory prior to any system upgrades or reconfiguration.

Figure 2-7: Model 903 Dual Fiber Optic Transmission System (4VID, 8VID)
The FMB-X-2.5R card in the remote subrack optically multiplexes the 1310 nm uplink and 1550 nm downlink
on the same fiber with a standard 1310/1550 nm WDM. A second 1310/1550 nm WDM at the FMB-X-2.5C
card multiplexes the uplink and downlink to the receiver and transmitter respectively.
The remote FMB-X-2.5R includes an optical splitter to provide redundant signals over two separate
singlemode fibers. At the console module, one of the two fibers for each link is selected by the fiber switch
integrated with the FMB-X-2.5-C located in slot C. Hence the downlink is only present on one fiber at a time.
The fiber switching can be performed automatically or manually, depending on the position of the toggle
switch on the front panel of the FMB-X-2.5C card. Refer to section 3.1.2 for more information about the
FMB-X-2.5C.

2.5 Backwards Compatibility
The FMB-X-2.5 is not backwards compatible with the FMB-VTX, FMB-VRX or GLINK FMB-X cards.
Both remote and console FMBs must be replaced with the FMB-X-2.5 when upgrading. All FMB-X-2.5 cards
operate at 2.5 Gbaud on uplink (1310 nm) and downlink (1550 nm) and are compatible with existing video
cards, data cards, and high speed racks. In the case of medium speed racks, the FMBs and backplanes must
be changed out.
Contact factory for more information.
