GPS over fibre system for antenna cable extension
Extend the reach of an antenna feeder cable up to 10Km, and overcome the limitations of a coaxial cable system.
Background
To provide an input signal to a GPS repeater, or a device such as a Network Time Sychronization unit, an outdoor antenna would ideally be installed at the highest point on the outside of the building.
The length of the coaxial cable from antenna to repeater/receiver may have an adverse effect on signal strength and quality.
Coaxial cable limitations
Any, or all, of these factors may mean that it becomes impractical continually to increase the cable length.
GPS over fibre – a reliable and practical alternative
A point-to-point optical link consists of three main components:
RF-to-optical (TX) module – converts RF signals from the outdoor antenna into light pulses and transmits them down the optical fiber link.
Single mode optical fibre – SC/APC connectors (optionally FC/APC)
Optical-to-RF (RX) module – converts the light pulses back into RF signals and passes them to the GPS equipment (repeater | receiver | timing module).
