The Bosch Fiber Optic Series are transmission
products that provide efficient, high quality video and
data transmission via fiber optic cable. Fiber optic
signals are immune to ground loops, radio frequency
interference (RFI), electromagnetic interference (EMI),
and cross talk because the video carrier is infrared
light and is transmitted through a nonconductive fiber
optic cable. Interference-free operation ensures
reliable service. Unlike microwave, wire, and coaxial
cable transmission systems, fiber optic transmission is
difficult, if not impossible to tap. And, since fiber optic
cable is nonconductive and does not radiate a signal, it
is difficult to detect and locate. These compact
devices are available in a surface mount enclosure or
in a modular style package that can be rack-mounted
using an optional EIA 48 cm (19 in.) compatible rack
unit.

Installation/configuration notes
LTC 4641 and LTC 4642 Series
The LTC 4641 Series Transmitters and LTC 4642
Series Receivers are designed for transmission of
CCTV analog video signals. Efficient installation is
assured because there are no user adjustments
required. The wide bandwidth transmission capability
of these units enables clear, sharp black and white or
color pictures to be transmitted over long distances.
The compact transmitters are small enough to be
connected directly to a camera’s BNC connector,
thereby simplifying installation.

LTC 4628 and LTC 4629 Series
The LTC 4628 and LTC 4629 are a bidirectional
transmission system designed to implement a
complete CCTV system using a single optical fiber
cable. This system independently transmits an analog
video signal from the camera location to the controller
location, while simultaneously transmitting Bosch BiPhase control code from the controller location to the
camera location. The video channel is compatible with
monochrome or color cameras. The data channel is
compatible with control systems that utilize Bosch BiPhase, simplex RS-232, or RS-422 signals. Both units
incorporate LED indicators to provide quick visual
indication of the module performance.
