Title: Processing system for connection between single-mode optical fiber and multi-mode optical fiber
Inventor: IFUKURO SADAO
IPC: G02B6/26
Filed: 1988-03-22
Abstract: PURPOSE:To prevent transmission quality from deteriorating by making either or both of end surfaces of the single-mode optical fiber and multi-mode optical fiber uneven, and scattering light which is projected by the single-mode optical fiber by the unevenness and entering the scattered light into the multi-mode optical fiber. CONSTITUTION:When the single-mode optical fiber 1 and multi-mode optical fiber 2 are connected in an abutting state, the unevenness 3 is formed on either or both of the abutting end surfaces. The light projected by the single-mode optical fiber 1 is scattered by the unevenness 3 and made incident on the multi- mode optical fiber 2. The projection light of the single-mode optical fiber excites light beams in various modes when entered into the multi-mode optical fiber 2. Consequently, even if the abutting state at the connection part between the fibers changes, variation in waveform shape on a reception side is prevented.
