Name: G657A2 Ultra-Thin Fiber For FPV Drones
G657A2 single-mode fibre combines two attractive features: excellent low macro-bending sensitivity and low water-peak level. It is comprehensively optimized for use in O-E-S-C-L band (1260 -1625 nm).
Apply for all kinds of optical fiber cables: central loose tube, loose tube stranded, slot core, fiber ribbon cable construction, and etc.
Apply to: optical system of lower loss and higher bandwidth; especially for soft cable ,small package fiber optic components ,optical fiber coupler of metropolitan area network and other special places;
Suits for O, E, S, C and L waveband (range from 1260nm to 1625nm), fully compatible with G.652D, with advantages of low bending loss in compact space and better connectivity;
Meets the requirements of small installation diameter and small optical fiber processing system, in telecommunication bureaus, buildings and independent shelters.

Key Features Benefits:
Unmatched Bending Performance.
Featuring advanced G657A1 G657A2 fibers, our cables excel in tightbend scenarios common in FPV drone wiring harnesses and gimbalsEnioy significantly lower microbending and macrobending losses compared to standard G652D fiber, ensuring stable sional transmission everin complex routing paths.
Ideal for: Compact drone designs, vibration-prone environments, flexible cable management.
Ultra-Slim & Lightweight Design:
Avallable in 0.25mm, 0.27mm, and 0.3mm diameters, our bare fiber minimizes weight and bulk - a critical advantage for FPV drones whereevery gram counts. The reduced size allows for easier integration into tight spaces without compromising signal integrity
Ideal for: Weight-sensitive FPV builds, high-density cabling, long-range setups.
High-Quality Single Mode Transmission:
Utilizing ITU-T G,6520 and G.657A1A2 standards, these fibers quarantee low attenuation and high bandwidth for crysta-clear, long-distancevideo and data transmission essential for FPV racing, cinematography, and industrial drone operations
Ideal for: HD/4K video feeds, low-latency control signals, reliable telemetry.
High-Capacity Reels for Efficiency.
Optimize your production or project with large spool options: 25.2KM/reel and 50.4kW/reel. Minimize splicing, reduce waste, and lower overallcosts for bulk users and manufacturers
Ideal for: Drone OEMs, system integrators, large-scale FPV projects.
Durable Black Colored Coating:
The black UV-curable acrylate coaing provides essential protection during handling and installation while ofering excelent visual identicationagainst backarounds.lt ensures mechanical robustness suitable for drone integration.
Ideal for: Easy tracing in complex builds, enhanced durability, professional aesthetics.
Application
All cable constructions, 1260~1626nm full band transmission, FTTH high speed optical routing, optical cable in small bend radius, small-size optical fiber cable and device, L-band.
