U-Band Reflector can be used
for Fttx fiber trouble-shooting monitoring. The combination of the OTDR and
U-Band Reflector can detect and locate the fiber faults in minutes, protect
investment of unused fibers, and reduce the cost of maintenance.
U-Band Reflector can be
realized by two solutions: Fiber Bragg Grating based FBG Reflector and Thin
Film based TFR. Both solutions are available in T&S, and FBG Reflector has
been granted China patent and US patent. According to the standard ITU-T G.982,
reflectance of any optical component between ONU and OLT should be better than
-35dB, which makes FBG Reflector a perfect solution.
The U-band reflectors are
provided with different encapsulation forms to fit different applications.
Customized encapsulations are also available.
