Product Description

Type

Low Loss Bend Insensitive Single-mode Optical Fiber （G652D+G.657A1）

Standard

The fiber comply with or exceed the technical specifications in ITU-T G.652.D /G657.A1.

Feature

Ø Superior anti-bending property;

Ø Fully compatible with G.652 single-mode fiber. Full band (1260～1626 nm) transmission;

Ø Low PMD for high bit-rate and long distance transmission. Extremely low micro-bending attenuation, applicable for all optical cable types including ribbons;

Ø 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.
