Company Profile

G657A1 Single Mode Fiber Cable 1260 Nm Single Mode Fiber Patch Cable

Product Application

Bend-insensitive single-mode fiber for access networks boasts all the features of the non-dispersion-shifted one and enjoys even more excellent bending performance at 1260 nm- 1625 nm transmission wavelength. In conditions where long-wavelength bending is required, its bend radius can be minimized to 10mm.

The fiber applies to different structures of fiber optic cables, especially tight-buffered and drop cables, ideal for Fiber to the Home (FTTH) and Fiber to the Building (FTTB).

Product Features

Bend-insensitive single-mode fiber for access network exceeds the parameters specified in ITU-T Recommendation G. 652. D/G.657.A and IEC60973-2-50 B1.3 standards. It invests in VAD technology, which results in a single-mode fiber's stable refractive-index profile, precise geometric size, and extremely good bending performance.

The singlemode fiber has completely eliminated water absorption around 1383nm, providing expanded transmission wavelengths from 1260nm to 1625nm; its superior bending performance can meet the special demands on the bend radius; it is compatible with the existing fibers under G.652.D Standards; its precise geometric size ensures low loss and high strength splice; what's more, its PMD contributes a lot to the long- and medium distance high data rate transmission.
