EasyBand® Ultra Bending Insensitive Single-mode Fibre

YOFC EasyBand® Ultra fibre is designed specifically for Fibre-To-The-Home (FTTH), enterprise network and any other applications where ultra low bending-loss at small bending radii is needed.
Applications

• All types of fibre patch cord with different structures

• High speed optical routes for Fibre-To-The-Home(FTTH) networks

• Cables with extreme low bending requirements

• Small-sized optical component

Product standards

YOFC EasyBand® Ultra fibre's macrobending performance and optical performance are superior to those recommended in ITU-T G.657.B3 and IEC 60793-2-50 B6.b3. Down to 5 mm bending radius, EasyBand® Ultra can meet the complex installation conditions in MDU and FTTH, such as wall corner, stapling, high load tension, etc.

Characteristics

• Superior to standard ITU-T G.657.B3 fibre, bending radius down to as small as 5mm and full compatibility with all G.652.D fibres

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

• Low bending loss for highly demanding cable designs including ribbons

• Accurate geometrical parameters and large MFD which insure low splicing loss and high splicing efficiency

• High nd value satisfying long service life in minimum bend radius
