50/50 Dual Window 1 ×2 Fiber Optic SC Coupler/Splitter 1310/1550nm
Optic Coupler Brief Introduces:
DWC (Dual Window Couplers) are Single Mode Splitters with a defined
split ratio from one input fiber to 2 output fibers. This DWC is a
1x2, with 1 input and 2 output fibers with a 90:10 split ratio and
250µm bare fiber. 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 Dual Window
Couplers come with no connectors for easy splicing or
connectorization. Connectorized Dual Window Couplers are available
with your choice of Fiber Optic Connectors: LC/UPC, LC/APC, SC/UPC,
SC/APC, FC/UPC, FC/APC, and ST/UPC.
