Description
A 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 do Singlemode (1310/1550nm) and Multimode
(850nm). Cable diameter can be 0.9mm, 2.0mm,3.0mm, Single window, dual window, and three windows 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 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 0.9mmloose tube single mode 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.
