Which item is used to convert 250um to 900um?

• A. Fanout Kit
• B. Breakout Kit
• C. Patch Panel
• D. Splice Closure

Answer: (A)

A fanout kit is used to transition a fiber from a 250 µm buffered size to a 900 µm size. The 250 µm buffer around the fiber is small and easy to terminate, but many installations and drop cables use a 900 µm protection sleeve for mechanical strength and routing. The kit provides pre-assembled sleeves, heat-shrink tubing, and ferrule components that safely and mechanically expand the small-diameter fiber into the larger 900 µm form, making it compatible with standard 900 µm drop cables and patching setups. This is different from a breakout kit, which is intended to separate a multicore or bundled cable into individual fibers; a patch panel is a mounting/termination point, and a splice closure protects field splices.
