High Speed Digital Fiber-Optic Links for Control, Video and RF Telemetry Data from Remote LocationsBlake, George R. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / With the advent of high-speed parallel-to-serial conversion interface standards
reaching the 1.6 gigabit per second region, it is now possible to remote entire
telemetry tracking systems over long distances without the need to maintain receivers,
combiners, computers and antenna control units at the pedestal. In addition, it will
soon be possible to digitize the RF signal(s) with high-speed flash-video
analog-to-digital converters and transfer the data over these same links. This coupled
with the improvements in fiber-optic L.E.D. and laser transmitters/ receivers and the
constantly decreasing cost of fiber-optic cable, will allow for the eventual elimination
of copper cabling for these interfaces. This will net a cost savings for the end user,
provide for easier installations and increase the reliability of the overall system.
This paper gives a brief history of the development of high-speed fiber-optic interface
links, then expands into current interface standards and their utilization (such as MIL-STD-1553B, fiber data distributed interface (FDDI), HIPPI, etc.). Finally, a glimpse
into the future of telemetry systems and the possibilities to soon be realized as major
manufacturers of fiber-optic interfaces push well into the gigabit region.
Topics include:
• Replacement of existing copper cables between controller and pedestal using
fiber-optic cable with interfaces that are not software-based intensive (black
boxes);
• Multiplexing pedestal control and status lines, RF feed commands, scan
reference signals, and boresite video camera control;
• Connecting and controlling multiple controllers and/or pedestals through one
common interface cable;
• Operating multiple tracking stations through one remote antenna controller;
• Digitized RF telemetry signals sent along with pedestal, feed, video commands
and status.
