250um Type SM 1X2 Coupler 1310/1550nm 10/90 Split Ratio 1M Length
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.
