Dual Window Coupler 1550nm Fiber Optic Splitter Singlemode
1x2 1310/1550nm Singlemode Dual Window Coupler Splitter 1:99 Split 0.9mm
Description
1x2 1310/1550nm Singlemode Dual Window Couplers manufactured by ANC International Co., Limited are Single Mode Splitters with a defined split ratio from one input fiber to 2 output fibers. This dual window coupler is a 1x2, with 1 input and 2 output fibers with a 1: 99 split ratio and 900µm loose tube fiber. Dual Window Couplers are available with 900µm loose tube single-mode fiber or 250µm bare fiber and are terminated or unterminated as required. Unconnectorized SM Splitters/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, ST/UPC, etc. Single mode Dual Window Couplers are manufactured using Corning SMF-28® Fiber and available in various coupling ratios such as 50/50, 40/60, 30/70, 20/80, 10/90, 05/95 & 1/99 with operating wavelengths 1270, 130, 1350, 1400, 1480, 1550 & 1630. Other coupling ratio & wavelength options are available upon request.
