摘要： An insertion hole for inserting an optical fiber is formed at a case, and then a resilient leaf spring and an operating button are stored in the case. The leaf spring is comprised of a through-pass hole formed at the central part of the leaf spring in correspondence with the insertion hole, a plurality of resilient lock claws extended from the circumferential edge of the through-pass hole toward the center thereof, and a groove recessed from a part of the circumferential edge in an outward direction. The operating button is provided with a stem of which part can be fed into or out of the case, the stem abutted against both edges of the groove is pushed under an operation of the stem, thereby a held state of the lock claws against the optical fiber can be released indirectly.

摘要： A beam-splitting/coupling apparatus comprises first and second frame member which each have a contact surface and a beam guide path. An optical filter is provided between the contact surfaces with the front and rear surfaces of the optical filter held by the first and second frame members respectively. The first and second frame members are held in a case by external flexible forces. A beam propagates from the beam guide path of the first frame member to the beam guide path of the second frame member by way of the optical filter. As a result, the optical filter can be installed firmly with ease. In addition, the effect of the installed optical filter on optical performance can be reduced.

摘要： A lens is fitted into a metal ring that covers the outer peripheral surface of the lens and can be soldered to a fixture member. The side cylindrical part of the metal ring is expanded toward the outer peripheral direction thereof by the pressure of the optical material put inside it, and, thus expanded, it defines the final dimension of the metal ring. One of the two openings formed on both sides of the side cylindrical part of the metal ring is so designed as to have a curving cylindrical part that extends from the side cylindrical part, and this curving cylindrical part is folded toward the optical functional face of the optical device to construct a metal ring-fitted optical device.

摘要： Disclosed herein is an optical communication connector. A connector optically couples between a pair of plastic fibers and a pair of silica fibers, and a connector optically couples between the other ends of the silica fibers and a pair of plastic fibers. In such a construction, signal light is bidirectionally transmitted using these fibers. The connector is provided with one condenser lens within a casing. On the side of the transmission of signal light from the silica fiber to the plastic fiber, end surfaces of both cores P and Q are brought into intimate contact with each other. On the side of the transmission of signal light from the plastic fiber to the silica fiber, end surfaces of both cores P and Q are opposed to each other with the condenser lens interposed therebetween. The other connector is also constructed in a manner similar to the above connector.

摘要： In an optical transmitting and receiving module, a transmitting light beam having a wavelength &lgr;1 emitted from an light-emitting device passes through an optical demultiplexing filter and enters an optical fiber, and a receiving light beam emitted from an end face of the optical fiber is reflected from the optical demultiplexing filter and is incident on a light-receiving device. A cover for covering the front space of the optical demultiplexing filter is placed on a casing block, and a tongue piece serving as a returning-light preventing unit is formed on the cover. When a transmitting light beam emitted from the light-emitting device is reflected from the optical demultiplexing filter, the direction in which the reflected light advances is changed by the tongue piece so that the reflected light is not incident on the light-receiving device.

摘要： An optical transmission/reception module in which an LD, a lens holder, which supports a lens, a partial wave filter, a lens holder, which supports a lens, and an optical fiber are all mounted to a housing block, coaxially along a first axis. A reflecting mirror, a lens holder, which supports a lens, and a PD are also mounted to the housing block, coaxially along a second axis which is parallel to the first axis. Cutouts are formed in the housing block for providing large openings forwardly of and perpendicular to a mounting surface for mounting the partial wave filter thereon and a mounting surface for mounting the reflecting mirror thereon. In such an optical transmission/reception module, it is possible to maintain the precision with which a partial wave filter, which passes a transmission light therethrough, and a reflecting member, which reflects a reception light, are mounted to a desired mounting angle at a high level, and to reduce assembly costs.
