0.25mm 0.27mm G657A2 Optical Fiber for Fpv Drone High-Definition Video Signal Transmission Cable

Product Description

0.25mm 0.27mm G657A2 Optical Fiber for Fpv Drone High-Definition Video Signal Transmission Cable

The G657A2 single-mode optical fiber is specially designed for applications requiring high bend resistance and flexibility, making it ideal for FPV (First-Person View) drone signal transmission. It maintains stable optical performance even in extremely tight spaces and sharp bends, ensuring uninterrupted, high-speed data flow. This fiber complies with ITU-T G.657.A2 standards and is widely used in lightweight, miniaturized aerial communication systems.
 

Optical Fiber and Cable bending insensitive single mode fibre meets or exceeds the ITU-T Recommendation G.652.D/G.657.

A1 including the IEC 60793-2-50 type B1.3/B6.a1 Optical Fibre Specification.

Characteristics:
• Low attenuation satisfying the operation demand in O-E-S-C-L band

• Good bending loss resistance at short radius bends

• Low bending loss for highly demanding cable designs including ribbons

• Low PMD satisfying high bit-rate and long distance transmission requirements

• Accurate geometrical parameters that insure low splicing loss and high splicing efficiency

Standard length: 25.2KM/50.4KM/60KM Or other lengths are also available
