Introduction
The Focal Model 914 High Definition Video Multiplexer (914-HDE) is a compact and rugged video, data and
Ethernet multiplexer and fiber optic transmission system designed for industrial environments and other
applications requiring the transmission of HD video, data and Ethernet over an optical link. The 914-HDE has
been optimized for low power operation and delivery of low latency, uncompressed 3G/HD/SD-SDI video.
A series of expansion cards are available, allowing additional composite video channels, serial data channels,
and Ethernet ports to be added to any 914-HDE system without requiring extra fibers of wavelengths.
This manual provides 914-HDE users with detailed information relevant to the design, configuration, installation,
and operation of the 914-HDE system. This manual and the appropriate reference documents should be
reviewed prior to installation or configuration of the multiplexer system.

System Overview
914-HDE systems are used as pairs (one remote and one console) to provide a transparent HD video and data
link over optical fiber(s). The installed optical transceivers determine the maximum optical link speed, fiber type,
number of fibers (1 or 2), and link distance. The card version sets the operational bandwidth, which is
independent from the optical data rate. The optical link uses a proprietary data protocol ensuring reliable
transmission with extremely low latency using highly efficient and dynamic bandwidth utilization.
Typically, the uplink (remote to console) and downlink (console to remote) are combined on a single fiber –
multimode or singlemode (standard) –with a passive optical coupler known as a wavelength division multiplexer
(WDM). Standard systems operate with 1310 nm uplink and 1550 nm downlink wavelengths. In larger systems,
multiple 914-HDE units 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 3-1 illustrates an example of a 914-HDE system configuration using a standard, standalone 914-HDE,
which supports the multiplexing of one (1) 3G/HD/SD-SDI channels, two (2) bidirectional RS-232 / RS-485 /
RS-422 serial data channels and one (1) Gigabit Ethernet channel over a single optical fiber.
Note that the HD video source (e.g. from an HD camera) is connected at the remote end. The HD video output
is provided at the console end (e.g. to an HD monitor).
The expansion connector supports 6 expansion card ports: 2 low speed and 4 medium speed ports. Optional
expansion cards are detailed in Section 5.0.
The external fiber optic system includes optical components such as optical connectors and a Fiber Optic Rotary
Joint (FORJ).

3.5 Ethernet Port
The 914-HDE provides an un-switched, low latency 10/100/1000 BASE-T(X) Ethernet link through the optical
port. Ethernet frames are guaranteed across the optical link in less than 2 frame times (frame size x Ethernet
link speed) plus a typical fiber link latency of 5 ns/m. The part is default configured for 10/100 BASE-T(X) in the
L1 version, and 10/100/1000 BASE-T(X) for M1 and H1 versions. Auto-negotiate settings can be accessed via
the Model 914 Diagnostic GUI. A standard 8P8C (RJ45) modular jack provides the mechanical interface for the
Ethernet port. The port is auto MDI/MDIX capable, and supports jumbo frames up to 9000 bytes.
An optional “Link Fault Pass Through” can be enabled on firmware revisions B1 or newer. This feature will
disconnect the Ethernet link if the far side is not linked. Therefore the system must be linked on both sides for

3.7 Diagnostic LED Header
The 914-HDE card includes a 10-pin header capable of driving 8 LEDs. This is useful for LED integration into
an enclosure. Each LED pin is driven low to turn on an LED, and includes a 267 ohm resistor in series to limit
the current draw. Maximum current draw is 8 mA.
This header may optionally become an input via the diagnostic GUI with firmware revisions greater than B1.
The LED header is FCI P/N 20021521-00010T1LF, and the mating part is FCI P/N 20021444-00010T1LF. This
can be used with most 0.050” (1.27mm) spacing ribbon cables.

3.8 Optics
An SFP or SFP+ transceiver provides the optical interface for the 914-HDE. Many options exist including:
Singlemode or multimode fiber
Bi-directional 1310/1550 nm transceivers (L1 and M1 versions)
Bi-directional 1270/1330 nm transceivers (H1 version)
CWDM wavelengths
Higher or lower optical budgets
Due to the high data rates, singlemode fiber is recommended. Multimode fiber is only suitable for very short
links (< 300m). Typical link budgets for single mode fiber are 20dB for bi-directional single fiber or 24dB for dual
fiber CWDM. Focal Technologies has compatible CWDM modules that can be mounted and stacked with 914-
HDE systems.
Contact the factory for specific part numbers.
3.8.1 Flux Budget Calculation
When specifying an optical system, it is important to analyze system losses and fiber link distances in order to
calculate the required optical configuration. The following table shows a sample flux budget calculation for a
system with multiple ST bushings, a 10km singlemode fiber link and a FORJ. Actual losses can vary widely
from this, each system flux budget calculation must use data based on actual parts in use.

3.8.2 Optical Safety
All lasers used in the 914-HDE system are Class I laser devices per IEC-60825 unless otherwise specified in
installation or configuration drawing. No special control measures or warning labels are required, although any
needless exposure of the eye should be avoided as a matter of good practice, and fibers should never be
viewed with magnifying instruments, e.g. fiber scopes, while optical power is present. Note that the optical
wavelengths are in the infrared range, so not visible, but magnifying instruments can still cause damaging levels
to the eye.

Model 914 Diagnostic GUI
The 914-HDE has advanced diagnostics available over a dedicated RS-232 port on the console 914-HDE. This
one port gives access to all 914 cards in the 914-HDE stack. This diagnostic link is critical during the setup
phase of any system, as it gives access to the settings of any port in the system. This is useful to configure
serial port protocols, Ethernet negotiation settings, and any special video settings, for example.
Included with every 914-HDE Console PCBA is a pigtailed jumper for the RS-232 diagnostic port, as shown in
the figure below. This cable plugs into J8 on the 914-HDE PCBA. To install the cable, the plug is pressed down
into the connector.
