FBT is a bundle of two or more fibers together and melt draw on the tapering machine, and real-time monitoring splitting ratio changes, splitting ratio to meet the requirements after the end of the melt draw, one end of an optical fiber to retain (the rest cut) as the input end and the other end is long on the road output. Our tapering process can only pull 1 × 4 or less. 1 × 4 or more devices, with more than 1 × 2 are connected together, then the whole package in the splitter box.
Tapered optical splitter features:
1. Additional low loss
2. Low polarization dependent loss
3. Good stability
4. Double working window
5. The three working window
6. wavelength high isolation
7. Small volume
8. The split ratio optional
Tapered optical splitter Application:
1. The optical fiber communication systems
2. LAN
3.CATV
4.FTTH
5. Fiber Optic Sensor
6. Measuring Instruments
