Fiber optic cable splitter multimode fiber

Multimode fiber optic splitters are passive devices that divide an incoming optical signal into multiple output signals while maintaining low insertion loss and stable performance.

Overview

A multimode fiber optic splitter is a passive optical component used to split or combine light signals in multimode fibers. These splitters are essential in applications where a single light source needs to be distributed to multiple devices or sensors, such as in optogenetics, environmental monitoring, fluorescence detection, and fiber optic networks. Types of Multimode SplittersPLC (Planar Lightwave Circuit) SplittersSymmetric multimode PLC splitters can split signals into two or more outputs.

They operate over a broad wavelength range, typically 650–1350 nm, covering common multimode fiber wavelengths like 650 nm, 850 nm, and 1300/1310 nm. Available for 50/125 µm and 62. 5/125 µm fibers (OM1, OM2, OM3, OM4).

Features include wavelength insensitivity, mode insensitivity, low insertion loss, and high stability.

Fused Fiber Splitters

Manufactured using a fusion-tapering technique, creating a monolithic structure. Offer uniform splitting ratios and bidirectional operation with low loss. Available in 1xN splitter configurations for distributing light evenly or NxN combiners for mixing multiple sources.

Core diameters range from 50 µm to 400 µm, with various numerical apertures (NA) to match multimode fiber specifications.
