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

GL FIBER^® 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
