FIBERFUTURE 1×4 ABS box single mode FBT fiber optic splitter uses fused biconical taper technology to divide incoming light into four outputs with customizable ratios. Designed for single-mode fibers, it supports a range of connector types including LC, SC, FC, and ST, or can be supplied unconnectorized. Available in 900µm loose tube and 250µm bare fiber configurations, this splitter is housed in a protective plastic enclosure to ensure durability. Ideal for FTTH, PON, and CATV applications where reliable signal distribution is critical.
Customizable coupling ratios.
Low crosstalk and minimal excess loss.
High optical return loss.
Dual or triple wavelength operation.
Optional connector terminations (SC, FC, LC, ST, custom).
Compatible with 250µm/900µm fiber, 2mm or 3mm buffer.
Splits 1310nm or 1550nm signals.
Equal 25:25:25:25 coupling ratio.
±40nm bandwidth per center wavelength.
Various fiber cable diameters available.
FTTH, LAN, PON, Optical CATV.
Local ring networks, fiber communication systems.
Fiber test equipment, fiber sensors.
