Building sway due to wind can be a problem as it disrupts the alignment between the two transceiver units causing loss of signal. Divergent beam technology can be used to allow the units to communicate in these situations but performance is still slightly affected.

Allen Wrench - 5/64. An Allen wrench is also known as a Hex key. It is a small handheld tool used for turning bolts and screws which have hexagonal sockets.

The basis of Free Space Optics communication is rather straightforward with a pair of transceiver units housing an optical receiver and transmitter, allowing the sending and receiving of data simultaneously, and an optical source with a focusing lens. The unit at one location transmits a beam of focused light carrying the information directly at the unit at the receiving location where the light beam is then transferred to an optical fibre from a high sensitivity receiver.

While Infrared Germanium Aspheric Lenses offer remarkable optical advantages, they do require careful handling and cleaning. As with all germanium optics, exposure to germanium dust should be minimized, and proper cleaning techniques using compatible solvents are essential for maintaining their performance.

Unlike rain and snow, – which generally has little effect on Free Space Optics communication -fog and water vapour droplets are a real hindrance to the operating performance. The small water droplets can at points completely stop the light beams from being received due to light absorption, refraction scattering or even complete reflection which can significantly lower data rates. Therefore in foggy areas, Free Space Optics may not be the best solution, however applications have been successfully carried out that have provided acceptable reliability with redundancy systems in place. The following five points listed all refer to the signal attenuation caused by atmospheric conditions.

Aspheric lenses, unlike traditional spherical lenses, have a non-uniform curvature, resulting in a more complex surface profile. This precision design allows for the correction of various aberrations, such as spherical aberration, coma, and astigmatism. Infrared Germanium Aspheric Lenses leverage this advanced design to deliver enhanced image quality, sharper focus, and reduced optical distortions, all of which are critical in IR applications where precision is paramount.

Scattering occurs when certain wavelengths experience collisions with objects and are redistributed in varying directions without energy loss (unlike absorption). Scattering is more likely to have a more frequent and larger effect over long distances where it can have a significant effect on beam strength.

Beam spread, or more technically called beam divergence, is measurable angular effect of the beam’s dissipation at a constant rate as it travels further through the atmosphere.

Free Space Optics wireless network ranges are typically found to be between around 100m and 2km but due to the nature of the signal strength being directly affected more by atmospheric conditions over increasing distance, the shorter the range between the two unit locations the higher the performance and availability of the connection will be

FSO is generally deployed well above ground – typically in rooftop locations.  This is the opposite for fibre / fibre optic cable,  which is typically installed under road or street level.  Therefore very different challenges are presented when considering Free Space Optics performance with the biggest being atmospheric conditions. However, most drawbacks and shortcomings can be resolved through the inclusion of redundancy systems and correct wireless network planning.

Due to light not be able to travel through opaque mediums, objects such as birds, planes and people can momentarily cause interruptions to the service by blocking the Free Space Optics’ light beam, with service resuming instantly when the light path is cleared. Multi-beam technology can be used with compatible systems to try and counter this problem.

Free Space Optics provides speeds comparable to those of optical fibre connections with the flexibility and practicality of being part of a wireless network providing bandwidth speeds typically advertised as up to 10Mbps, 100Mbps, 155Mbps and 1.5Gbps, with possible speeds of up to 10Gbps becoming likely in the future, plus the potential of being able to use WDM (Wavelength-Division Multiplexing) technology. Currently, the only other wireless technology capable of these kinds of speeds is Millimeter-Wave RF Wireless Networking which, in comparison, requires licensing and can affected severely by rain. Due to the received beam being transferred onto an optical fibre to connect to the core network, trouble free integration and easy set up make Free Space Optics networking’s compatibility with any system very high.

Germanium possesses several essential characteristics that make it well-suited for IR applications. With its high refractive index in the IR range, Germanium Aspheric Lenses require fewer lens elements, resulting in reduced weight and improved optical performance. This feature makes them ideal for compact and lightweight IR imaging systems. Furthermore, Germanium exhibits excellent transmission properties in the IR wavelength range, typically from 2 µm to 14 µm, making it ideal for capturing valuable information in the thermal and near-infrared regions. This broad spectral range is crucial for various sensing and imaging applications. Moreover, Germanium’s remarkable thermal stability allows Infrared Germanium Aspheric Lenses to perform reliably in environments with varying temperatures, making them suitable for IR systems that may encounter extreme conditions.

Fluctuations in signal strength can be caused by variations in temperature of air pockets between the transmitter and receiver due to natural differences or objects such as buildings etc. This effect, know as refractive turbulence, causes image dancing or blurring of the signal at the receiver end which results in amplitude loss.

Water vapour molecules in the air absorb the energy from photons (light particles) within the light beam which causes an overall loss in power density. The use of spatial diversity and correct system power helps combat this effect as absorption is more common at certain wavelength ranges of light.
