The LTC 4600 Series are transmission systems that
provide efficient, high quality video and data transmission
via a multimode fiber optic cable for improved CCTV
system performance. 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.

LTC 4641 and LTC 4642 Series
The LTC 4641 Series Transmitters and LTC 4642 Series
Receivers are designed for transmission of CCTV 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 4744 and LTC 4745 Series
The LTC 4744 Transmitter and LTC 4745 Receiver are
designed for the transmission of up to 4 CCTV video
signals using one multimode fiber cable. This link operates
in the 1310 nm range and incorporates 8-bit video
encoding exceeding the requirements of EIA RS-250C for
Medium Haul video transmissions. Integral LED status
indicators provide an indication of operating parameters.
LTC 4630 and LTC 4631 Series
The LTC 4630 and LTC 4631 are a bidirectional
transmission system designed to operate with Bilinx-
compatible video/data CCTV products using a single
multimode optical fiber cable. This system independently
transmits a video signal from the camera location to the
controller location, while simultaneously transmitting
Bilinx control/event data in both directions. The video
channel is compatible with both NTSC and PAL color
cameras. The data channel is compatible with all Bilinx-
compatible control systems and cameras. Both units
incorporate LED indicators to provide quick visual
indication of the module performance.
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 a video signal from the
camera location to the controller location, while
simultaneously transmitting Allegiant 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 simplex RS-232 or RS-422
signals. Both units incorporate LED indicators to provide
quick visual indication of the module performance. The
