■ G.657A2 Bare Optical Fiber: G.657A2 Bare Optical Fiber as the Key for Improved Flight Range and Control Stability of FPV Drones.
In an age where UAVs are becoming the standard, an aircrew's ability to communicate effectively with their aircraft over long distances and transmit HD video quickly is crucial. For FPV pilots and UAV professionals, the use of RF technology entails various hurdles, including lag, signal loss, and distortion; these issues remain common and often render distant flying impossible beyond visual range.
ZION Communication brings forward the G.657A2 Bare Optical Fiber, a single-mode fiber for unique drone FPV communications, aiming to allow a new level of performance. With stability, precision, and performance hybridized together, it ensures the best and most dependable data flow over extreme operational distances.
ZION's G.657A2 fiber is composed of ultra-pure glass, rather thin compared to others, but still sufficient for its purpose - there is no wasting on signal loss over extended distances. This technology's drive combines stable drone operation and video feed under reliable distance of 50 km, with a lag that could be easily ruled out and the minimum transmission error.

The fiber G.657A2 possesses an unique feature to provide a great bent sensitivity in tight bends greater than 7.5 mm and less than 15 mm. This special feature enables it to be used for drone design and in very demanding environments.
Although this fiber has an extremely low-strength diameter of 0.25 mm, it is surely a tough one. The fiber can bear repeated reeling, vibrations, and mechanical stress without any detrimental effect on the signal quality during flight.
The G.657A2 may be supplied in spools of 50.4 km, therefore enough for ensuring the range capability and reliability required in industrial inspection, security surveillance, and cinematic aerial studies—this method is the FPV variant intended for longer distances.
Fiber for harsh conditions is designed to operate effectively over extremes of temperatures - at -40°C to +85°C, in contrast to low-grade fibers that lose their insulation qualities in harsh weather.
The G.657A2 fiber link from ZION Communication permits you to integrate an FPV system that provides the highest level of image and controls dynamic integration. Unlike typical wireless connections, fiber cable ensures that the communication is critical, secure, high-broadband, and interference-free.
Having the guarantee of ZION Communication's fiber of G.657A2 quality innovation, the fiber is not just a component, it is the network for the dawn of FPV performance. With the power of fiber, take total control over your flight range and vision with a crystal-clear and reliable connection.
