摘要： According to the present invention, as a result of using a depressed or trench-assisted light-receiving waveguide in which the core is surrounded by a layer having a refractive index lower than that of a cladding as light-receiving means for receiving light outputted from a multi-core optical fiber, the layer of a low refractive index can inhibit the propagation of noise, etc. from the cladding to the core. Consequently, even in cases where the inter-core crosstalk is small, it is possible to accurately measure the inter-core crosstalk since components different from crosstalk-derived components in optical power are reduced.

摘要： The object of this invention is to provide an optical connector module 1 in which the possibility of scraped wastes to exist between the lens and the tip face of the optical fiber is less and which has high optical coupling efficiency. The optical connector module 1 comprises: an optical fiber 2 having a core 2a and a plastic cladding 2b made of a first resin; a positioning device 3 made of a second resin and including a fixing portion 4 in which the optical fiber 2 is inserted; and a lens 5, wherein the hardness of the second resin is higher than that of the first resin. The tip face 2ac of a glass core 2a may protrude from the tip face 2bc of the cladding 2b toward the bottom face 4c, or otherwise the tip face 2bc of the cladding 2b may protrude from the tip face 2ac of the glass core 2a toward the bottom face 4c.
