Detail Information

Type

Bend Insensitive Single-Mode Optical Fiber G.657.A2

Standard

The fiber complie with or exceed the technical specifications in ITU-T G.657.A1/A2/B2.

Features

Minimum bend radius 7.5mm, superior anti-bending property;
Fully compatible with G.652 single-mode fiber. Full band (1260~1626nm) transmission;
Low PMD for high bit-rate and long distance transmission. Extremely low micro-bending attenuation, applicable for all optical cable types including ribbons;
High anti-fatigue parameter ensures service life under small bending radius.

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.

The company produces and tests optical fiber independently, all qualified fibers meet the requirements of technical specifications.

Packaging and storage

Ensure no foreign matter on the reel and fiber surface, wrap it with film and cover, and label fiber coding on the reel and cover respectively.

The packaged optical fiber is stored at a constant temperature of 25ºC in a light-proof warehouse. The products are fixed in the carton when they are shipped out of the warehouse. The carton number and fiber coding information are attached to the carton, and the electronic test report is attached to each shipment.
