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.

The LTC 4651 Transceivers are designed especially for
the transmission of Bosch Bi-Phase control code
signals used in the Allegiant Series of switcher/
controllers, various DVRs, multiplexers, and other
camera control systems. They are also compatible with
Manchester code and standard RS-232 signals. These
units operate in the 850 nm range and contain a
removable screw terminal type connector that allows
easy connection to the shielded twisted pair cable
carrying the control signal. These units can also be
used as an RS-232C transceiver that is compatible
with EIA Standard RS-232C levels. The system is
suitable for simplex asynchronous data transmissions
using one fiber, or full duplex asynchronous data
transmissions using two fibers up to 64 kbaud.

rack-mount LTC 4600 Series Fiber Optic Modules in a
standard EIA 48 cm (19 in.) rack. The unit incorporates
an integral power supply that supplies power to all
modules installed in the rack-mount unit. The supply
also utilizes a standard IEC AC power connector for
easy power cord replacement or exchange with
various worldwide AC power plug configurations.
Modules installed in the rack-mount unit can be hotswapped, so it is not necessary to power down the
rack when removing or replacing modules. The integral
power supply incorporates an automatic electronic
current limiting feature for each individual rack-mount
