Abstract
An optical connector which can prevent that light reflected on an end surface of a ferrule built in the optical connector may be returned to a transmitting side in the open condition of the connector. The optical connector includes a first ferrule and a second ferrule both slidably stored in a housing. The first ferrule has one end spherically polished and another end obliquely polished. The second ferrule has one end obliquely polished. The optical connector further includes a sleeve for coaxially holding the first ferrule and the second ferrule, a first spring for biasing the first and second ferrules away from each other, and a second spring for biasing the second ferrule toward the first ferrule. The first spring has a spring constant greater than that of the second spring.
