| Single Mode 9/125 G657B3 | |||||||||
|
|||||||||
The single mode fiber meets or exceeds the ITU-T Recommendation G.657.B3 and the IEC 60793-2-50 type B1.3 Optical Fiber Specification.
It is designed specifically for Fiber-To-The-Home(FTTH), enterprise network and any other applications where ultra low bending-loss at small bending radii is needed. Down to 5 mm bending radius, Ultra can meet the complex installation conditions in MDU and FTTH, such as wall corner, stapling, high Load tension, etc.
