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.
