Lfiber’s mode-insensitive multimode fiber coupler (optical splitter) is a passive optical device used for splitting incoming signals into two or more output signals. They’re capable of operating over a broad wavelength range (i.e. 850 and 1300/1310 nm). Both 50/125 and 62.5/125 (OM1, OM2, OM3 and OM4) fibers are available. This multimode fiber coupler (optical splitter) features mode-insensitive, low insertion loss, high stability and reliability. Related Products ↓

Lfiber’s multimode fiber coupler (optical splitter) is Telcordia GR-1221/GR-1209 and RoHS compliant. It works well even in the outdoor application or harsh environment.

Mode-insensitive Multimode Fiber Coupler (Optical Splitter)

Fiber fusion technology has proved to be simple, versatile and effective, allowing the industrial implementation of several kinds of branching devices for a variety of applications. Lfiber has excellent fused biconic taper (FBT) technical solution in the heat treatment of fiber. With the FBT method, bare or etched fibers are brought into contact, stretched, sometimes twisted, and fused so that evanescent mode coupling occurs along the interaction length. We have reduced the effects of modes in the fiber cladding, for example, by using an etched fiber. Lfiber’s multimode fiber coupler (optical splitter) is mode-insensitive, it performs uniform performance across an ultra wideband wavelength range and features high reliability and stability.

Different kinds of multimode fiber splitters and combiners are now available. Please visit fused-fiber optic products to see more related products.
