Product Details

Description:

GL FIBER® 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.


Application:

• 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


Feature Characteristics:

1. 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
2. Low attenuation satisfying the operation demand in O-E-S-C-L band
3. Low bending loss for highly demanding cable designs including ribbons
4. Accurate geometrical parameters and large MFD which insure low splicing loss and high splicing efficiency
5. High nd value satisfying long service life in minimum bend radius

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, GL FIBER® Ultra can meet the complex installation conditions in MDU and FTTH, such as wall corner, stapling, high load tension, etc.
