Optical Fiber Single Mode G.657A1 9/125 Bare Fiber spool bend insensitive

Application: 1.Short pitch cables for special application 2.High performance optical network operating in OESCL band 3. High speed optical routes in building (FTTx) 4. Cables with low bending requirements
  • product details

Bare optic fiber ITU-T G.657 A.1 is bend insensitive.  Designed to bend at small radius of down to 10mm radius and 7.5mm radius. Best for FTTH application.

Product specification:

1. Low attenuation satisfying the operation demand in O-E-S-C-L band.

2. Good bending loss resistance at short radius bends

3. Low micro-bending loss for highly demanding cable designs includding ribbons.

4. Accurate geometrical parameters that insure low splicing loss and high splicing efficiency.
