Laser Multimode Couplers/Splitters/Taps

Introduction:
With the advent of gigabit networks, multimode fiber (MMF) links are using laser transmitters. These transmitters do not fill the mode-structure of MMF like LEDs. Therefore, traditional FBT (fused biconic taper), multimode couplers and splitters do not function correctly. Fiberdyne Labs, Inc. Laser multimode splitters function correctly with the restricted mode structure of laser transmitters (e.g. VCSELs, vertical cavity surface emitting lasers), which are typically used in 1Gb and 10Gb multimode data links. Now you can add monitoring to your high-speed multi- mode links using Fiberdyne laser-optimized multimode splitter/coupler.
