What is the small square component in an optical fiber coupler

An SC/APC fiber optic adapter is a passive mechanical interface used to join two SC connectors that have angled physical contact (APC) ferrules, typically polished at 8°. Fiber couplers belong to the basic components of many fiber-optic setups. Note that the term fiber coupler is used with two different meanings: It can be an optical fiber device with one or more input fibers and one or more output fibers. It covers a wide range of fiber optic devices such as optical splitters, optical combiners, and optical couplers. A fiber optic coupler is a device that can distribute the optical signal. This small, inexpensive component is critical for aligning and mating two SC/APC connectors while preserving low insertion loss and ultra‑high return loss performance. Its core function is to distribute (split) or combine (combine) optical power while maintaining the spectral composition of the signal. The device allows the transmission of light waves through multiple paths. It functions by dividing a single incoming light path into multiple outgoing paths, or by combining light from several input paths into a single output fiber. This capability is fundamental. [PDF]
