1310/1550nm 1x2 FBT Fiber Optic Coupler
Stainless-Steel Tube with 0.9mm SC/APC Connectors
Description
The 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 function, the optical splitter is a very important part of passive optical networks (PON). FTB Fused fiber splitter (coupler) can be Singlemode (1310/1550nm) or Multimode (850nm). The cable diameter can be 0.9mm, 2.0mm, and 3.0mm. Single window, dual window, and three-window are available.
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 1x2 and 2x2 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 0.9mm loose tube single mode fiber or 250um bare fiber and terminated or unterminated as requested.
Unconnectorized DWCs come with no connectors for easy splicing or connectorization. Connectorized DWCs are available with choices of Fiber Optic Connectors: LC/UPC, LC/APC, SC/UPC, SC/APC, FC/UPC, FC/APC, and ST/UPC.
