Optic Fiber cable Pilotix G657.A2 0.25mm, 60.5km/roll

Product detailed description

Optical Fiber Cable G657.A2 (0.25 mm), 60.5km / Roll

Optical Fiber Cable G657.A2 is designed for long-distance, high-bandwidth data transmission in systems where radio communication is limited or unavailable. The fiber provides stable signal transmission with low attenuation and is suitable for use in drone communication systems, robotic platforms, and other applications requiring reliable fiber-optic links.

G657.A2 fiber is engineered with improved bending performance, allowing stable signal transmission even at small bending radii while maintaining low signal loss.

The cable is manufactured according to ITU-T G.657 and IEC 60793-2-50 standards and is optimized for bending-loss insensitive single-mode optical communication.

Important Notes:

- For communication distances up to 9 km, a 20 km transceiver is recommended.

- For communication distances 10–14 km, a 40 km transceiver is recommended.

- For communication distances 15–20 km and more, a 60 km transceiver is recommended.

- Pilotix fiber optic communication modules are compatible only with transceivers from the same series. Compatibility with other series is not guaranteed.
