Abstract: An optical connector includes: a ferrule holding an optical fiber; a holder holding the ferrule; a protection sleeve including a tip that is fixed to a sleeve fixing portion of the holder; an inner housing in which at least a part of the sleeve fixing portion is housed; and an outer housing in which at least a part of the inner housing is housed. The inner housing includes a tab portion that tilts in a radial direction of the ferrule and applies a pressure on the protection sleeve by tilting inward in the radial direction in a state in which the tab portion is disposed inside the outer housing.

Abstract: A jig for a fusion splicer mountable on a heater of the fusion splicer includes: a plate part configured to face a heating part of the heater; a first retainer, configured to face a first clamp of the fusion splicer that is disposed outside of the heating part along a longitudinal direction of an object to be heated, and further configured to retain a first member extending from a first end of the object along the longitudinal direction; and a second retainer, configured to face a second clamp disposed on a side of the heating part opposite to the first clamp along the longitudinal direction, and further configured to retain a second member extending from a second end of the object along the longitudinal direction.

Abstract: An optical connector includes: a ferrule that holds an end part of a fiber; and a holding member including: a holding part that slidably holds the ferrule; a fixing part through which the fiber extending from the ferrule is inserted and to which a sleeve for protecting a fusion splice point between the fiber and an optical fiber is fixed; and a housing part that houses the fiber between the holding part and the fixing part when the fiber is bent and the ferrule moves rearward of the housing part.
