Product Application
Bend insensitive singlemode fiber for access network boasts all the features that the non-dispersion shifted one has, and enjoys even more excellent bending performance at 1260nm-1625nm transmission wavelength.
In conditions that long wavelength bending is required, its bend radius is minimized to 7.5mm, while its additional attenuation at 1625nm wavelength is 0.8dB. The fiber applies for different structures of fiber optic cables, especially for tight buffered cable and drop cable, ideal for Fiber to the Home (FTTH) and Fiber to the Building (FTTB).
Product Features
Bend insensitive singlemode fiber for access network exceeds the parameters specified in ITU-T Recommendation G.652.D/G.657.A2 and IEC60973-2-50 B1.3/B6 Standards.
It invests in VAD technology, which results in single-mode fibers' stable refractive-index profile, precise geometric siz,e 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.
