摘要： A fiber optic ferrule includes a body extending from a first end to a second opposite end, with the body including an axial passage extending between the first and the second ends. The axial passage includes a first diameter portion having a diameter of at least 125 microns, a second diameter portion having a diameter of at least 250 microns and less than a diameter of a buffer, and a smooth and continuous transition between the first and the second diameter portions. The second diameter portion is positioned between the first diameter portion and the second end. The axial passage further defines a tapered shape at the second end extending inward from the second end toward the second diameter portion. In certain embodiments, another smooth and continuous transition can be provided between the taper shape and the second diameter portion. In certain embodiments, the axial passage is smooth and continuous between the first and the second ends of the body. A hub holds the ferrule. A method of assembling a terminated fiber optic cable is also provided.

摘要： An optical connector assembly includes a spring, a ferrule, a first housing, and a second housing connected to the first housing. The ferrule includes a ferrule body and a lens. The ferrule body defines a fiber receiver configured to receive optical fibers of an optical cable and a first spring receiver configured to receive the spring. The lens is arranged to optically communicate light propagated by the received optical fibers for free-space optical communication. The first housing defines a first opening configured to slidably receive and guide the ferrule for movement along a first longitudinal axis. The second housing defines a second opening configured to receive the optical cable therethrough along a second longitudinal axis, and a second spring receiver configured to receive the spring. The spring biases movement of the ferrule in the first housing away from the second housing.

摘要： An expanded-beam ferrule for an optical interface device has a ferrule body with a fiber support feature that supports an optical fiber. The ferrule body defines a lens having a planar back surface and a convex and aspheric front surface. The lens has a select amount of on-axis spherical aberration that gives rise to an improved coupling efficiency and in particular provided tolerance to misalignments between confronting expanded-beam ferrules used in an expanded-beam optical interface device. The ferrule body can also include multiple lenses and can support multiple optical fibers in operable alignment thereto.

摘要： The present invention relates to an MCF with a structure for enabling an alignment work with higher accuracy. The MCF has a plurality of cores and a cladding. An outer peripheral shape of the cladding in a cross section of the MCF is comprised of a circumferential portion forming a circumference coincident with an outer periphery of the MCF, and a cut portion. The cut portion has a bottom portion and two contact portions provided on both sides of the bottom portion and projecting more than the bottom portion. When a side face of the MCF is viewed, the two contact portions have flattened faces and the flattened faces of the two contact portions extend along a longitudinal direction of the MCF with the bottom portion in between.

摘要： An optical fiber connector includes optical fibers, a connector body, and positioning members. The optical fibers are received in the respective through holes, and pass through the respective first recesses, the respective separating portions, and the respective second recesses, and aligned with the optical lenses. The three engagement posts of the positioning member are arranged above a through hole and surround a receiving room. The three engagement posts and a separating portion cooperatively retain an optical fiber in the connector body.

摘要： An optical connector which enables an operator to easily remove a ferrule from a housing without using a special jig by himself alone. A supporting member that is mounted in a housing in a manner capable of being inserted and removed in a state in which the ferrule is held therein, includes a supporting member main body which is accommodated in the housing, and an operating portion which temporarily releases an engagement between protrusions formed on the supporting member main body and through holes formed in the housing. The operating portion is arranged in a manner protruding outside the housing when the supporting member is mounted in the housing.

摘要： An optical connector having: a ferrule into which a first optical fiber is inserted; an optical fiber connector disposed at an back end of the ferrule; and a cross-linkable refractive index matching member attached onto an end face on a back end side of the first optical fiber. The end face on the back end side of the first optical fiber and an end face of a second optical fiber to be inserted into the optical fiber connector from a back end side thereof are to be connected by a butting connection. The cross-linkable refractive index matching member is formed such that a cross-linkable refractive index matching agent is coated on the end face on the back end side of the first optical fiber, and the coated agent is cross-linked and hardened.
