Frequently Asked Questions

* What is Infra Red Data Transmission System ?
 
Free Space Optical Communication Systems are wireless connections through the atmosphere communicating by light wave transmission. Infra Red Systems work basically the same as fibre optic cable except the beam is transmitted through open space rather than glass fibre. The carrier used for the transmission of this signal is infra red and is generated by either a high power LED or a laser diode. The Systems operate by taking a standard data or Telecommunications signal, converting it into a digital format and transmitting it through free space. Infra red is well suited for communicating at high data rates and is a cost effectivbe solution foir satisfying the increasing bandwidth requirements of high performance networks.
 
Is Infra Red proven Technology ?
 
Over the last few years the technology has grown to include systems that can satisfy a large number of applications that include LAN/Netwrok connections, PABX extension, last mile connection to Metropolitan fibre rings, PCS and celluar backhaul traffic.
 
Are these Lasr Systems Infra Red ?
 
Our Laser systems operate in the light spectrum. The laser light transmitted across the link is at a wavelength of 690 to 980 nm
 
What is the Data Rate and Throughput?
 
Our Infrared Systems provide full channel speeds from E1 to 1.25 Gigabit Fast ethernet or fibre. Our Systems deliver uncompressed data rates at Full Duplex and they are transparent to the customer networks.
 
Whjat are the benifits of using Laser Communication Technology ?
 
* Full Channel speeds
* No license requirments
* Highly secure
* Compatible with copper or fibre interfaces
* No bridge or router requiremensts
* Cost effective rapid pay back on investment
* No recurring line costs
* Internal or external mounting
* Excellent availability
* Fully portable
* Resistant to temperature and climatic changes
* Zero latency over all distances
* Transparent to networks and protocols.
* Rapid implementation as opposed to Microwvae Licenced installations
* Multiplexed systems of E1 and 100 Fast Ethernet are now installed in Australia
 
Are Special licences or Permits required ?
 
There are no requirements for ACA licences. The equipment complies with a class licence guidelines of which can be seen on the ACA web site
 
How much maintenance or adjustment is required ?
 
When installed correctly, infr red transmission systems require very little maintenance, however, an annual maintenance contract is suggested. ITA SYSTEMS accredited dealers proivide a pre-installation site survey
which identifies the particular site design criteria. They will install and commission to the customers requiremensts.
 
How easily can Infra Red Systems be installed ?
 
The units can be installed and operational in one day. More difficult installations take a little longer.
 
How secure is Laser Based Communications ?
 
* Laser transmission has a narrow optical beam which is not accessible unless viewing into the transmitter beam.  Any potential intrusion will result in an interruption of the data transmission which alets the customer
* The existence of laser beams cannopt be detected by spectruim analysers or RF meters.
* Various proprietary transmission protocols are used which provide additional security
* Laser systems have been used for many diverse applications requiring confidential ccommunications including financial, medical and military networking.
 
What about performance availability ?
 
Correctly installed and commissioned Infra Red and Laser Systems can achieve an operational availability of 99.9 % or more. Our Alcom system has autotracking, auto beam focussing which can increase availability considerably over other infra red and laser systems.
 
Can Infra RedL/Laser transmit through glass ?
 
Infra Red and Laser systems can transmit through glass, however, the physical properties of the glass, including reflective coatings need to be considered and each application needs to be evaluated carefully. Please contact ITA SYSTEMS to discuss your application
 
Do these systems create a safety hazard ?
 
All systems utilise  a single broad area, wide divergence beam in both directions and meet ACA class licence regulations for such systems
 
What types of applications does Infra Red/Laser Transmission systems fit ?
 
The worls user base is wide and varied. zTher is no one key factor other than the need to efficiently and cost effectivel;y transfer information between sites at high speed. Users currently include  : hospitals, power stations, manufacturig, retailers, educational institutions, private medical facilities, banking, airports, motor racing, miliotary, telecommunication utilities, Internet providers, CCTV, door entry systems,
