Cablefree 'Lite'

Similar in design concept to the advanced Cablefree 622 ,Access & Gigabit systems, the Cablefree 'Lite' is a small, cost-effective communications link for use over short hops of around 200m. The Cablefree 'Lite' offers a choice of either 2.048Mbps G703 or 10Mbps Ethernet interfaces, providing the user with a low-cost solution for data connectivity at a keenly competitive price.
Rather than offering the full range of data interfaces, upgradeability or advanced features of the other Cablefree products, the Cablefree 'Lite' has been optimised for operation at lower data rates and contains all the design features which contribute to the excellent performance of all Cablefree systems.

The Cablefree 'Lite' is available only with interfaces either for G703 / E1 at 2.048Mbps or Ethernet at 10Mbps. Applications which require higher data rates are better suited to the Cablefree 622. The Cablefree 'Lite' will operate at ranges up to 200m with excellent link availability figures exceeding 99.7% in all weather conditions. System can be used with both mains and low voltage power supplies or light weight battery packs.

The advanced design features give the Cablefree 'Lite' superior performance over comparable infrared free-space communications systems. In adverse weather conditions such as rain, fog, snow, smog and thermal shimmer, the built-in ‘fade’ margin ensures uninterrupted data transmission. The use of ‘wide beam’ technology overcomes potential problems of vibration and building movement ensuring correct beam alignment at all times.  All Cablefree systems have very minimal maintenance requirements.

The Cablefree 'Lite' system is supplied as a pair of full-duplex transceiver units in IP65 environmentally protected casings, together with optional wall-mount or tripod fixings and power supplies. The system has in-built alignment aids, link-test and basic diagnostic functions to facilitate installation and service.

Cablefree 'Lite' incorporates numerous safety features and has been certified to be eye-safe to the requirements of IEC825 and BS EN60825.
