Fiber Optic Products for Unmanned Aerial Vehicles (UAVs)

Nowadays fiber optic transmission is increasingly finding widespread use. Fiber optic products have the advantages of long transmission distances, in addition to an attractive data rate, noise immunity, small size and a light weight. Network-centric models send sensor and payload information to ground-control stations, satellites, and remote terminals. A fiber optic communication system consists of three main components:

  • optical transmitter
  • fiber optic cable
  • optical receiver

The optical transmitter converts an electrical signal to optical signal. The fiber optic cable carries the optical signal from the optical transmitter to the optical receiver. And after that, the optical receiver reconverts the optical signal to electrical signal. The most commonly used optical transmitter is semiconductor devices like LEDs (light-emitting diodes) and laser diodes.

Network-centric models and computer-based processing are needed both to identify important pieces of information and for data compression for unmanned aerial vehicles (UAVs). Reduced size and light weight are essential to design features for UAVs: saving on vehicle weight is highly crucial for allowing UAVs to remain stationed for a longer period on time, and to load heavier cargos. Such small savings at the component level translate to much larger savings at the level of the entire system. In order to prevent bottlenecks in performance, input/output connections need to keep pace with processors to ensure that data is transferred rapidly and resourcefully. In addition to this, the increasing demand for more efficient instruments mean that typical connectors are not compatible for high-speed systems: the appropriate solution needs to be extremely hardy in order to withstand the extreme climate and conditions experienced on placement with UAVs. However, it should be noted, high-speed signals are more difficult to control than ones transmitting at a lower speed. It becomes harder to manage factors such as return loss, insertion loss, and crosstalk, which can cause signal strength to decline. Size, weight, and power issues persist as vital in enabling consistent surveillance, an efficient fuel-to-weight ratio, and the possibility for smaller-sized UAVs. Fiber optic cables and probes provide the bandwidth and transmission capabilities required with the added benefit of EMI and RFI immunity, making this an ideal solution for these applications.

The trend for fast fiber optic transmission is increasing over recent times. The two main types of optical contacts are physical contact (PC) and expanded beam (EB). The non-contact EB interface enables high-mating-cycle resilience and simple cleaning, whilst the PC interface delivers lower loss.

Optromix offers high-performance, high-quality specialty optical fiber cables that cover the range from UV (180 nm) to the mid-infrared (18 μm) for such applications as environmental sensing, space and military applications, and industrial manufacturing.
