1.0 Introduction
Focal Technologies' Model 907 is a compact and rugged video/data multiplexer and fiber optic transmission
system designed for Remotely Operated Vehicles (ROV) and other applications requiring the transmission of
video and/or data over an optical link. The Model 907 has been optimized for low power operation and
delivery of high quality video and data in a standard PC/104 form factor. A flexible design architecture
supports modular reconfiguration and expansion of the multiplexer system by changing or adding cards to the
system.
This document provides Model 907 users with detailed information relevant to the design, configuration,
installation, and operation of the Model 907 Video/Data Multiplexing system. This manual and the appropriate
reference documents should be reviewed prior to installation or reconfiguration of the multiplexer system.
Section 2 provides an overview of the complete Model 907 multiplexer system and the key technologies
employed. Section 3 provides an overview of the Model 907 motherboard modules. Section 4 provides an
overview of the available Model 907 media converter cards. Section 5 describes the available Model 907
expansion cards. Section 6 describes additional system module cards, e.g. optical modules, which further
extend the capabilities of the Model 907 system. Section 7 follows with detailed information on the Model 907
optical system, and Section 8 provides useful installation instructions and preliminary test procedures.
Appendices include lists of fuses, a cross-reference for card configuration drawing and any system specific
information, if provided, such as relevant installation drawings and configuration drawings.

Focal Technologies Corp. Page 2-1
2.0 System Overview
Model 907 systems are built up from four main types of cards: motherboards, expansion cards, media
converters, and system module cards. A Model 907 system consists, as a minimum, of a Model 907 remote
motherboard (multiplexer), intended for installation at the ROV or subsea end, and a Model 907 console
motherboard, intended for installation at the shipboard or surface end. Expansion cards may be stacked on
top of motherboards to provide increased number of data channels or add signal formats not supported by the
motherboard directly.
Motherboards combine several video and/or data channels into a single, high-speed optical link. Video and
data signals input at the remote motherboard and attached expansion cards are time division multiplexed
(TDM) into a single, high-speed optical uplink. Similarly, data signals at the console end are combined via
TDM into a single, high-speed optical downlink.
The uplink and downlink are typically combined on a single fiber – singlemode or multimode – with a passive
optical coupler known as a wavelength division multiplexer (WDM). Basic systems usually operate with a
1310 nm uplink and 1550 nm downlink. In larger systems, multiple stacks of 907 cards may be combined on a
single fiber using a coarse wavelength division multiplexer (CWDM) to take advantage of the high bandwidth
of optical fiber.
Figure 2-1 illustrates an example of a system configuration using a standard, standalone 907 motherboard,
which supports the multiplexing of three channels of video and six channels of bidirectional data over a single
optical fiber using WDM, in this example, passed through a fiber optic rotary joint (FORJ). Typically several
connectors, not shown, would add 1-3 dB of loss.

Model 907 media converter cards provide direct conversion of a single, high-speed electrical channel, such as
Gigabit Ethernet, into optical signaling at one end of the system, and conversion back into the original data
format at the other. Media converters can be used as standalone cards or can be assembled in a stack with a
motherboard. CWDMs can be added to combine optical signals from multiple media converters, and/or the
motherboard, onto a single optical fiber.

An example of a Model 907 stack is shown below in Figure 2-2, in this case a Model 907V motherboard
(907-V) with two 8-channel RS-485 expansion cards (907-485).

3.0 Multiplexer Motherboard Cards
Both the remote and console ends of the optical link incorporate a 907 motherboard. The motherboards
multiplex video and/or data channels, transmit the combined data over the optical link, demultiplex received
data from the optical link, store system diagnostic data, and provide power to other cards in the stack. All
motherboards can be operated as standalone cards or be assembled together in a stack including
907 expansion cards, media converter cards, and system modules.
Motherboards are typically supplied with a singlemode or multimode wavelength division multiplexer (WDM)
for operation over a single fiber, or without a WDM for two-fiber links. In the case of two-fiber communications,
optical multiplexing can be provided on another card in the stack, or the two-fibers can be used to link directly
from a remote motherboard to a console motherboard. On-board and off-board optical multiplexer
configurations are illustrated in Figure 3-1. Furthermore, motherboards may be configured to use CWDM
wavelengths and couplers to allow data/video from other cards, which have their own optical transceivers, to
be combined on the same optical fiber.

The flexibility of the optical link between motherboards enables a wide range of application requirements.
Cards configured to use singlemode, high-power, and high-sensitivity CWDM transceivers satisfy large-
bandwidth, long-distance data and video transfer applications, whereas cards configured to use multimode,
low power, and low-sensitivity transceivers satisfy applications requiring lower bandwidth, shorter distance,
and lower cost.
Model 907 cards are available in pressure tolerant versions with up to 6000 psi rating.
