Product Description

In Stock G657A2 Bare Optical Fiber SM 0.25mm Fiber Optic Cable 50.4km/roll

Optical fiber optic cable for UAVs have become an ideal choice for UAV communication and data transmission due to their excellent bending performance, low attenuation, high mechanical strength and wide environmental adaptability. Its compact and lightweight design and compatibility ensure efficient operation in a variety of complex environments.
The standard single-mode fibre has an outer diameter of 125 microns and a coating diameter of 250 microns, making the lightweight design suitable for the miniaturisation needs of drones. Lightweight, high-strength jacket materials such as Kevlar or aramid fibres are used to increase protection while reducing weight.

The G.657A2 is capable of operating with a small bend radius (minimum dynamic bend radius of 10 mm and static bend radius of 7.5 mm), reducing signal loss. It can maintain high performance even in complex wiring environments, and is suitable for the needs of the drone's compact structure and frequent movement. At a wavelength of 1550 nm, a typical attenuation factor of 0.22 dB/km or less ensures efficient optical signal transmission. Able to withstand a tensile force of at least 400 Newtons, ensuring durability and reliability in a wide range of environments. It has a wide operating temperature range, typically between -40°C and +85°C, and is suitable for different climatic conditions. It has good mechanical stability and can resist the vibration and impact during the flight of the drone. 

Features

•Excellent bending resistance within the range of 7.5-15mm bending radius
• Fully compatible with G.652 single-mode fiber
•Low attenuation, meeting the requirements of the O-E-S-C-L operating band
•Low polarization mode dispersion (PMD), meeting the needs of high-speed and long-distance transmission
•Used in various optical cables, including ribbon cables, with extremely low bending additional losses
•Accurate geometric parameters ensure low welding loss and high welding efficiency
• Has high anti fatigue parameters to ensure service life under small bending radii
