Single Mode

Single mode ﬁber optics are designed speciﬁcally to allow the transmission of a

very narrow range of wavelengths within the core of the ﬁber. As the precise

wavelength control required to accomplish this is performed using lasers, which

direct a single, narrow ray of light, the transmissive core of single mode ﬁber

optics is typically very small (8 to 10 µm). Single mode ﬁber is more expensive to

produce than multimode ﬁber, and is typically used in long-haul applications.

Due to the very demanding tolerances involved in connecting two transmissive

media with diameters approximately one-quarter as thick as a sheet of paper,

single mode ﬁber optics require very precise connectors that will not move or

shift over time. For this reason, single mode ﬁber optics should only be

terminated with locking, preferably keyed, connectors. Fiber optic connector

types such as the ST, SC, or FDDI MIC connector all meet the requirements of

single mode ﬁber optics, if installed and tested properly.
