We all are familiar with optics and optical communication. But have you heard about free space optics? Free space optics technology (abbreviated as FSO), also known as open-air photonics or optical wireless or infrared broadband, transmits information from point-to-point and multipoint using powerless infrared lasers.
Unlike traditional copper wires or fiber-optic technology, that transmits information by light across glass, FSO uses laser technology to transmit optical signals through the air using mirrors and lenses to focus and direct the beams and send information from one chip to another. FSO technology doesn’t need a spectrum license.
FSO first appeared in the 60’s, for military applications. During end of 80’s, it appeared as a commercial choice but technological restrictions prevented it from success. Low capability, Low reach transmission, severe alignment issues as well as vulnerability to weather interferences were the main drawbacks at that time. Nowadays, the optical communication without wire is evolved! , FSO systems guarantee 2.5 GB/s taxes with a carrier class availability. LAN and Metropolitan access networks are reaping the advantages.
The use of free space optics is especially interesting once we understand that the majority of consumers doesn’t possess access to fibers as well as fiber installation is expensive and demands long time. Moreover, right-of-way prices, difficulties in obtaining government licenses for new fiber installation etc. are additional issues that have turned FSO into the option of choice for short reach applications.
Now let us see some of the benefits of Free Space Optics:
Very high wireless bandwidth:
The LaserFire system provides a full Gigabit Ethernet interface link whereas accepting fiber input/output pairs. The LaserFire system isn’t restricted to a selected bandwidth, and provides Gigabit Ethernet in normal installations with variability depending on the application.
Reduce the cost of wasted time:
Lots of time and money is lost throughout the laying of fiber, days or even weeks of valuable time may be spent fro digging and burying pounds of fiber optic cables with significant duty equipment, all while having to consider tough obstacles. With LaserFire, a 5 kilometer line of communication can be up and running in just one or two hours.
Uninterrupted wireless communication:
The LaserFire system is good for stable vehicle-to-vehicle, building-to-building, or tower-to-tower communications where high capability fiber optic cable isn’t desirable. As said before, this method is extremely fast and simple to deploy and withdraw. The information transmission isn’t affected by, nor does it interfere with RF transmissions and may be deployed in RF-denied environments.
Safe to use:
All LaserFire systems are skin and eye safe at the aperture and meet category 1M laser standards.
Using LaserFire free space optics permits for fast point to point data transfer without the requirement for tearing up dirt or trees whereas burying fiber optics. LaserFire also uses less power than your normal household appliance.
Compatible with multi-protocol:
The only requirement for the LaserFire system is an optical supply. Any network hardware that contains a fiber output, regardless of protocol, is often used with the LaserFire system. Further, space Photonics also offer an intelligent gateway to invisibly convert between protocols for reliable information transmission.0
