LTC 4744 and LTC 4745 Series
The LTC 4744 Transmitter and LTC 4745 Receiver are
designed for the transmission of up to 4 CCTV analog
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 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.
