165 um Reduced Diameter Bending Insensitive Fibre

YOFC 165 um fibre realized reduced fibre outer diameter with excellent bending performance thanks to its bending insensitive fibre design, furthermore, by reducing the outer clad’s thickness, YOFC 165um fibre’s glass part diameter is only 80 um and has the similar MFD to standard G.657.B3 fibre.

YOFC 165 um reduced diameter bending insensitive fibres delivers the outstanding bending performance to a 5 mm radius for demanding applications while maintaining compatible with conventional G.652.D and G.657 fibres. It is an excellent choice for application where small size, small bend radii may be encountered.

Applications

Small-sized optical component

Characteristics
  • Outstanding bending performance and compatible with G 652.D and G.657 fibres.
  • Proof-tested to 200 KPSI to ensure reliability.
  • 56% less CSA than conventional 250 μm coated fibre enabling smaller size optical component.
