Dual Window Wideband Fiber 1x2 (2x2) Single-Mode Fiber Fused
Couplers
Optic Coupler Brief Introduces:
Fiber optic couplers are used to split the input signals into two
or more outputs, they are called splitters in this case. On the
other hand, some types of couplers can be used to combine two or
more inputs into one single output, they are called combiners in
this case.
Geehe offers fiber optic couplers/splitters. These are available in
Single Mode or Multimode. Splitters with a defined split ratio from
one or two input fibers to 2 output fibers. The available split
counts are 1x2 and 2x2 or 1x4 1X8 in split ratios of 50/50, 40/60,
30/70, 20/80, 10/90, 5/95, 1/99, 60/40, 70/30, 80/20, 90/10, 95/5,
and 99/1. Dual Window Couplers are available with 900µm loose tube
single-mode fiber or 250µm bare fiber and terminated or
unterminated as per your needs. Unconnectorized DWC's come with no
connectors for easy splicing or connectorization.
Connectorized DWC's are available with your choice of Fiber Optic
Connectors: LC/UPC, LC/APC, SC/UPC, SC/APC, FC/UPC, FC/APC, and
ST/UPC.
