Description

Type

Low loss Bending-insensitive compatible Single-mode Fiber ( G.652D-LLBI )

Standard

The fiber complie with or exceed the technical specifications in ITU-T G.652.D /G657.A

Features
  • Superior anti-bending property.
  • Reducing significantly the attenuation of the 1260~1625nm full band 
  • Fully compatible with G.652 single-mode fiber. Full band (1260~1626 nm) 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, including ribbon, loose tube stranded, slotted core, central tube, tight buffered designs, FTTH high speed optical routing, optical cable in small bend radius, small-size optical fiber cable and device.

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

Packaging and storage
  • Ø   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.

    Ø   The packaged optical fiber is stored at a constant temperature of 25 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.
