Optical link device

An optical link device for being connected to an optical connector formed such that a pair of optical fibers are supported by a connector section, said optical link device comprising:

• an optical communications package comprising a device positioning member having prescribed wiring patterns and on which a photo detector and a light emitting device are placed as photoelectric converters, and leads for connecting contact terminals of the photo detector and the light emitting device with an external device;
• a sealing cap that is attached to the device positioning member of the optical communications package and that seals the photo detector and the light emitting device airtight;
• a pair of condenser lenses that guide incident light to one of the photo detector and the optical fiber;
• a housing, in which at least the optical communications package, the pair of condenser lenses, and the sealing cap are placed;
• a receptacle for being coupled with the housing and with the connector section of the optical connector;
• a pair of sleeves into which the respective optical fibers are inserted when the connector section is coupled with the receptacle;
• and
• a pair of stoppers against which the tips of the optical fibers inserted into the respective sleeves are butted and for positioning the pair of optical fibers, wherein
• the sealing cap, the pair of condenser lenses, and the pair of stoppers are unitized as a single unit member.
