Abstract

An optical terminal structure includes a single mode optical fiber having a short length, and a cylindrical member in which the single mode optical fiber is fixed. The cylindrical member is coaxial with the core of the single mode optical fiber. The cylindrical member has at each end a facet that is polished to a mirror finish. The core and a clad of the single mode optical fiber have refractive indexes such that the normalized frequency in the operation of the single mode optical fiber becomes at most 2.405 as a value converted at a wavelength in use of 1.28 µm. The wavelength in use is preferably in the range of 1.29 to 1.33 µm.
