The temperature controlled multi-channel TOSA generally includes an array of lasers to emit a plurality of different channel wavelengths. The lasers may be thermally tuned to the channel wavelengths by establishing a global temperature for the array of lasers such that the amount of heat communicated to each laser is substantially the same. The global temperature may be established, at least in part, by monitoring the shortest channel wavelength and/or a temperature of the lasers. The temperature of the lasers may then get increased via a shared heating device in thermal communication with the lasers until the shortest monitored wavelength substantially reaches the nominal shortest wavelength or the measured temperature substantially equals the global temperature.

The sealing enclosure loosely receives a connector within a connector volume so that the connector, which may be of a standard type used in electronic or optic data transmission, may be displaced within a plug face at the forward end of the connector volume. The connector may compensate variations in the position of a mating connector with respect to the mating enclosure. The sealing enclosure allows to seal off the connector volume and engage the sealing enclosure with a mating enclosure in a single motion. This is affected by having a cable seal interposed between an inner body and an outer body. If the outer body is moved forward to engage the mating connector, the cable seal is squeezed between the cable and the inner body sealing off the connector volume at the rearward end of the inner body.

  • Patent number: 10401577
    Abstract: A multi-core optical fiber connection device comprises a first multi-core optical fiber connector and a second multi-core optical fiber connector. The first multi-core optical fiber connector comprises a first joint unit. The second multi-core optical fiber connector comprises a second joint unit. The second contact receptacle unit comprises a movable jacket and a movable ring. As long as the movable ring is pulled, the first joint unit is pushed by the movable jacket so that the first multi-core optical fiber connector and the second multi-core optical fiber connector are separated from each other, which achieves the effect that the first multi-core optical fiber connector and the second multi-core optical fiber connector are quickly connected with each other and separated from each other by one-hand operation.

  • Patent number: 10345536
    Abstract: The present invention discloses an optical fiber connector, comprising: a housing, a ferrule installed within said housing; an end sleeve, connecting to the rear end of said housing; and an optical cable clamp, installed by insertion within said end sleeve, being provided for the purpose of clamping an optical cable. Said optical cable is secured within said optical cable clamp, and after said optical cable clamp is inserted and secured within said end sleeve, the optical fiber of said optical cable is inserted within said housing and butt-joined with the embedded optical fiber within said ferrule. As a result of this, before the butt-joined optical fibers are locked in, the optical cable has already been secured within the optical cable clamp and fixed to the connector housing. Therefore, the butt-joined optical fibers cannot be separated due to the effects of unexpected pulling force, thus ensuring the optical fiber of the optical cable reliably abuts the embedded optical fiber.

  • Patent number: 10211560
    Abstract: A network jack assembly network connection identification system comprising an identifier receiving cavity extending inward from a surface of a plug body section of the jack and an identifier element designed for insertion into the identifier receiving cavity. The identifier receiving cavity is accessible through any of a sidewall, a top wall, a bottom wall, or a front wall of the plug body section. The cavity may include a lens enabling viewing of the identifier element. The identifier can be a partially or completely colored surface of the identifier element, a shaped feature of the identifier element, etc. The identifier can be a sheet of material, a pin, or any other suitable insertable component. In one variant, the identifier can be formed during installation by reshaping material designated therefore, such as a wax. Alternatively, the identification solution can be applied to a wall plate.
