1x2 Single Mode 1310/1550nm 0.9mm Loose Tube Dual Window Coupler
Optic coupler introduces:
1X2 FBT Splitter, Singlemode Dual Window, 0.9mm Loose Tube
Fiber Couplers are designed for splitting light with minimal loss
from one into two fibers or to combine light from two fibers into
one fiber. They are designed for power splitting and tapping in
telecommunication equipment, CATV networks, and test equipment.
Geehe can provide customized FBT splitters in a variety of styles:
single-window,dual-window, three window broadband couplers.
1×2 Bare Fiber Coupler Features:
- The small protective metal sleeve around the split fibers
- 2x2 50:50 Split ratio at 850nm for 50/125µm fiber
- 900µm loose tube fiber for easy stripping, splicing or terminating
- Also available pre-terminated with LC/UPC, LC/APC, SC/UPC, SC/APC,
FC/UPC, FC/APC, and ST/UPC.
- Available split ratios: 50/50, 90/10, and others in 1x2 or 2x2
