Abstract: A resin composition comprises: a base resin containing an oligomer, a monomer, and a photopolymerization initiator; and inorganic oxide particles, wherein the inorganic oxide particles are lump-shaped aggregated particles, and the volume average particle size of the inorganic oxide particles measured by an X-ray small angle scattering method is 5 nm or more and 800 nm or less.

Abstract: An optoelectronic module and optoelectronic connector assemblies can be used for releasable connection of a laser source to the module from a location exterior to the module. The construction of the optoelectronic connector assemblies is such that both in connection and disconnection, the electrical contacts are broken before the optical contacts so that the laser may power down before the optical connection is broken. The optoelectronic connection assemblies have blind mating features. Some versions are free of any latching or mechanical interconnection of the optoelectronic connector assemblies to each other. A spring has a construction which permits it to be received onto a cable by lateral movement of the spring.

Abstract: The present invention provides an optical connector coupled to an optical receptacle, wherein the optical connector comprises an outer housing, a coupling module, and a latch structure. The coupling module is arranged in the outer housing for slidably connecting to the outer housing. When the latch structure is rotated to a first position, the optical connector is unable to be released from the optical receptacle; and when the latch structure is rotated to a second position, the outer housing is allowed to slide relative to coupling module whereby the optical connector is released from the optical receptacle. In one alternative embodiment, the present invention further provides an optical module and an operation method for locking the optical connector into the optical receptacle, or releasing the optical connector from the optical receptacle.
