Distant Communications

FiberPlex Cable Driver/Receiver products extend copper media communication links beyond 1 kilometer. Fiber-optic Isolators convert electrical signals to lightwave for communication up to 2 kilometers on fiber-optic cables. The noise immunity of fiber is especially valuable on long cable runs.

Secure Communications

When data security is crucial, such as in TEMPEST and SCIF applications, electronic devices are shielded to contain their RFI emissions and avoid unauthorized access to the data. FiberPlex products can be used to make data, video and telephone connections across the shield barrier without compromising its shielding integrity. FiberPlex waveguides provide a shield penetration for non-conductive fiber-optic cables that inhibits RFI leakage. FiberPlex Isolators convert electrical signals to optical format for emission-free communications outside the shielded area. And our power line filters reduce RFI leakage on power lines.

Buffered Communications

FiberPlex Elastic Data Buffers provide dynamic storage for synchronous data systems that have slightly differing data clocks. One example is data from a satellite where Doppler shift is introduced by orbit dynamics. Another example is where there is a small difference between the clock frequency of two nodes in a communication link. Buffer size is determined by the cyclic rate of Doppler shift for the satellite example. It is determined by the continuous transmission time period that is to be accommodated in the case of different clock rates.

Noise-free Communications

Just as they do not emit RFI, fiber-optic cables are not disturbed by energy radiated from other sources such as heavy machinery, transmitters and even lightning. Fiber-optic cables are immune to both electrical and magnetic fields.

Synchronized Communications

The ultimate control of synchronous communications is synchronization of all clocks to a common source. A FiberPlex Timing Distribution System accepts clock input from a precision source such as a Cesium beam oscillator or GPS receiver and synthesizes all clock frequencies required in the network. When used with a satellite-based precision clock source such as GPS, the addition of an Elastic Data Buffer will eliminate Doppler shift effects on network timing.

Compatible Communications

FiberPlex Interface Converters accomplish electrical and mechanical connection between electronic devices with incompatible interfaces. They provide transparent communications between formats such as RS-232, RS-422, V.35 and MIL-STDs.
