1×2 Singlemode Dual window FBT Coupler with ST/UPC Connector 3.0mm ABS Cassette
Fiber optic coupler, is a device applicated in optical fiber systems with one or more input fibers and one or several output fibers.For the fused optical splitter,It can be divided into different ratios.such as 50/50 if the split is even, or 80/20 if 80% of the signal goes to one side and only 20% to the other.As a result of its great funciton,Optical splitter is a very important part in passive opitc networks (PON).FTB Fused fiber splitter (coupler) can do Singlemode (1310/1550nm) and Multimode (850nm).Cable diameter can be 0.9mm,2.0mm,3.0mm ,Single window,dual window and three window all we can supply .
Singlemode Dual Window Couplers are Single Mode Splitters with a defined split ratio from one or two input fibers to 2 output fibers. Available split counts are 1×2 and 2×2 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 availble with 0.9mmloose tube singlemode fiber or 250umbare fiber and terminated or unterminated as per your needs. UnconnectorizedDWC’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.
