Product Description

Bending-loss insensitive single-mode optical fiber bears the entire characteristics of non-dispersion shifted single-mode optical fiber and  superior bending performance, which is applicable to transmission over entire wavelength from 1260 nm to 1625 nm. Under the condition of long wave band, the bending radius could be as small as 10mm.

 

Characteristics

 

Bending-loss insensitive single-mode optical fiber is superior to standards of ITU-T Recommendation G.652D/G.657A and IEC International Standard 60973-2-50 B1.3.
The optical fiber perform is manufactured via the advanced VAD process. Due to the advantages of the fiber drawing process and the adopted VAD performs, G.657A1 optical fiber shows perfect refractive index profile,excellent geometrical performance, low bending loss etc.
(1) It completely overcomes the attenuation of water peak at 1383 nm and could operate over the entire waveband from 1260 nm to 1625 nm.
(2) Excellent bending performance, applicable to occasion with special requirement of bending radius.
(3) Completely compatible with existing G.652D.
(4) Accurate geometrical parameter ensures low splicing loss and high splicing performance.
(5) Excellent PMD performance supports high-speed and long repeater spacing transmission system.

 

Application

 

Applies to all types of optical fiber cable,especially indoor tight-buffer cable and bow-type drop cable, which is the essential part for FTTH and FTTB.
