SAFETY INSTRUCTIONS AND

COMPLIANCE DECLARATIONS

PLEASE OBSERVE THE FOLLOWING SAFETY

PRECAUTIONS AS OUR PRODUCTS CONT AIN

CLASS I LASER PRODUCTS

WARNING

Do not disconnect the fiber optic connector while the unit is powered
up. Exposure to laser radiation is possible when the laser fiber optic
connector is disconnected while the unit is powered up.

Although the fiber optic connectors in this product emit only Class 1
energy that is below the levels considered to be hazardous, one should
never stare directly into a fiber optic connector or an unconnected fiber
end unless one can be certain that no exposure to laser energy could
occur.

CAUTION

This manual is intended for use by trained service personnel. The use
of controls, making adjustments, or performing operations other than
those specified may result in hazardous radiation exposure.

The following label or equivalent is located on the surface of laser products.
This label indicates that the product is classified as a CLASS 1 LASER
PRODUCT.

CLASS 1 LASER PRODUCT

SURGE PROTECTION DEVICE RECOMMENDED

This product contains sensitive electrical components that may be
damaged by electrical spikes, surges, electric shock, lightning strikes,
etc. Use of surge protection systems is highly recommended in order
to protect and extend the life of your equipment.

1.0 PRODUCT DESCRIPTION

The BCI 250E/260E Series is a high performance unidirectional/
bi-directional transmission system capable of carrying simultaneous
broadcast quality analog video, audio, and/or data signals. The standard
single channel models (250E/260E) will transport one channel of broadcast
quality analog video, two audio channels, and/or one serial data channel
(RS-232/RS-422) over multimode or singlemode fiber. The 250E/260E
has a loop-though video monitoring port in the TX unit and has two output
video ports in the RX units. The video quality in the 250E/260E system
meets 250C short haul specifications, while its audio specifications exceed
professional standards. Many versions of optical transmitters and receivers
can be used in the 250E/260E to address a different distance coverage.

The 250E/260E features a digital fiber optic transmission technology,
capable of providing sharper video and crisp audio, high functional reliability,
and low operating cost with little or no maintenance. The quality of the
video, audio and data transmission is superior to the analog transmission
systems (based on the counterparts amplitude or frequency modulation)
schemes. No user adjustments are required in the 250E/260E system,
enabling for a quick setup with trouble-free operation.

The 250E/260E comes in two packaging options: a rugged standalone
unit, or a plug-in card for a card cage system. Panel connectors are
provided for video (BNC), audio (terminal block), and data (terminal block),
and fiber connection (FC-type for singlemode fiber or ST-type for multimode
fiber). They are also easily monitored by separate LED indicators for
power, optical link, and channel activity . See Figure 1-1 for the front and
rear panels of a 250E.

Due to its digital transmission design, the 250E/260E is capable of
addressing a variety of non-standard configurations.

2.0 SETUP

The BCI 250E/260E Series units are used in pairs. For unidirectional
applications, the 250E transmitter is located at the near-end, while a
250E receiver is connected at the far-end through one fiber. For
bi-directional applications, one 260E transceiver unit is located at the
near-end and connected through two optical fibers to an identical 260E
transceiver located at the far-end of the link. Each unit provides a separate
electrical interface connector for the audio, video, and data signals.
Connections are one to one between both units. Figure 2-1 depicts a
typical installation.

2.1 Mounting

Before installing the units into your housing, make sure there is
enough space to pull and connect both the electrical and optical
cables without stressing them beyond the manufacturer’s
limitations (also known as the bend radius minimum). Rack
Mount kits are available through special order.

2.2 Cabling and Connectors

In order to setup the BCI 250E/260E properly, make sure to
observe the following instructions when installing the proper
cables. The 250E/260E requires two parts to the cabling setup:
the electrical and the optical. For the optical part, observe the
following procedures, as there are various types of optical
connectors as illustrated on the following page.

2.2.1 Electrical Cable Connection

On the electrical side, it is required that the following steps
be observed when connecting the various audio, video, and
data terminal devices as they all require special attention,
and are the only available electrical connections. They are
described in the following steps.

2.2.1.1 Video Interface

The 250E/260E accepts 75-ohm video signal over coaxial
cable terminated to a BNC connector (e.g., RG 59U
with a BNC connector). (See Figure 2-2). For analog
video connections, observe the following instructions.

1. Connect the required video transmission source to
the VIDEO 2 BNC connector on the 250E/260E
unit.

2. Lastly, connect the VIDEO 1 BNC connector on
the 250E/260E unit to the required video receiver
unit(s). Y ou are now ready to transmit and receive
video signals.

2.2.1.2 Audio Interface

For the audio portion, observe the following steps.
(See Figure 2-3).
