A fiber optical transceiver includes a package, a plurality of lead frames provided with the package and protruding outward from the package, a first circuit board installed in the package and electrically connected to the plurality of lead frames, and an optical element provided on the first circuit board. The package includes a ceramic portion formed of ceramic and covered with a metallized film.

Fiber optical transceiver and optical communication module

An optical connector includes a housing in which a counterpart optical connector connected to a pair of optical fibers having a first optical fiber and a second optical fiber is fitted, a light emitting side lens portion accommodated in the housing, and in which a first end surface of the first optical fiber in the counterpart optical connector is disposed on one end side, a light receiving side lens portion accommodated in the housing, and in which a second end surface of the second optical fiber in the counterpart optical connector is disposed on one end side, a light emitting element disposed on the other end side of the light emitting side lens portion, and a light receiving element disposed on the other end side of the light receiving side lens portion.

Optical connector and optical connector device

An optical connector includes an optical filterthat is disposed between an end surface and a lens, and includes a through-hole that transmits part of the output light, when an inner diameter of the through-hole of the optical filter is denoted by B, a distance from the end surface to the optical filter in the optical axis direction is denoted by L, a maximum transmitted light output angle of transmitted light that passes through the through-hole and has a smaller angle than a maximum output angle &#x3b1; of output light is denoted by &#x3b1;', and an outer diameter of a core of an optical fiber is denoted by A, B=2&#xd7;L&#xd7;tan &#x3b1;&#x2032;&#x2212;A, and L&#x3e;A/tan &#x3b1;&#x2032;/2 are satisfied.

Optical connector

An optical element module includes a lead frame an optical element mounted on the lead frame, a resin housing including an opening part, and a tube body. The resin housing contains a part of the lead frame on which the optical element is mounted. The tube body includes a tube part for receiving an optical fiber terminal, a lens arranged between the optical element and the optical fiber terminal, and a lid part which covers the opening part of the resin housing. The tube part, the lens and the lid part are integrally formed.
