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 Bi-Phase 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 Bi-Phase, simplex RS-232, or
RS-422 signals. Both units incorporate LED indicators to
provide quick visual indication of the module
performance.
