KOCENT OPTEC
1 / 5
A fiber optic coupler is a device appreciated 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.
Optical splitters represent a vital component in passive optic networks (PON). FTB Fused fiber splitters (coupler) support Single mode (1310/1550nm) and Multimode (850nm). Single window, dual window, and three window configurations are all available.
Single mode Dual Window Couplers are Single Mode Splitters with a defined split ratio from one or two input fibers to 2 output fibers. The available split counts are 1x2 and 2x2 with split ratios including: 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 can be terminated or unterminated as per your needs. Unconnectorized DWC's come without connectors for easy splicing or connecting. Available cable diameters include 0.9mm, 2.0mm, and 3.0mm.
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 or other customized options. They feature small size, high reliability, low cost, and good channel-to-channel uniformity, and are widely used in PON networks to realize optical signal power splitting.
We provide a whole series of 1xN and 2xN splitter products tailored for specific applications. All products meet GR-1209-CORE and GR-1221-CORE standards.
