摘要： A highly flame retardant coated optical fiber excelling in not only environmental characteristics and mechanical characteristics but also optical transmission characteristics; and a coated optical fiber with connector including the same. In particular, a coated optical fiber comprising an optical fiber comprising a glass fiber having its outer circumferential surface provided with a primary coating layer, the optical fiber having its outer circumferential surface further provided with a secondary coating layer. The secondary coating layer consists of a second resin composition comprising a base resin and, per 100 pts.wt. of the base resin, 100 to 250 pts.wt. of a metal hydroxide and 10 to 100 pts.wt. of a nitrogenous flame retardant, the second resin composition not containing any halogen.

摘要： A light receiving device includes a microlens 21 located in each of regions corresponding to pixels, the microlens being disposed on a rear surface of an InP substrate 1. The microlens is formed by using a resin material having a range of a transmittance of light in the wavelength region between 0.7 and 3 µm of 25% or less, the transmittance being 70% or more.
