Cablefree 'Lite' -
Product Datasheet
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.
