  • Patent number: 10866372
    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: 10830960
    Abstract: A sealing enclosure is configured to connect to a mating enclosure. 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: 10680736
    Abstract: The invention relates to the field of optical communication network modules, and provides a 4-channel CWDM QSFP optical module, comprising a QSFP base and four optical transmitting sub-devices. The four optical transmitting sub-devices are mounted on the base in parallel, and there is a gap between each of the optical transmitting sub-devices and the base. The QSFP optical module further includes CWDM optical components for multiplexing 4-channel optical signals emitted by the four optical transmitting sub-devices. The CWDM optical components comprise a single fiber pigtail for transmitting the multiplexed optical signal, the single fiber pigtail being at least partially located in the gap. The 4-channel CWDM QSFP optical module of the invention connects the four optical transmitting sub-devices with the CWDM optical components by a reasonable method of optical fiber winding, thereby solves the problem that it is difficult to achieve single-mode fiber coupling of four LDs in a small space.

  • Patent number: 9933584
    Abstract: A duplex fiber optic connector plug includes at least one fiber optic connector, a first casing, a second casing and a release lever. The release lever is axially coupled to a surface of the first casing and has an end coupled to a release bracket of the fiber optic connector to form a seesaw design. During operation, the release lever is compressed by the force of the finger, so that an end of the release lever is elevated, and the other end compresses the release bracket downward to release from a fiber optic socket, so as to provide an intuitively convenient operation and improve the convenience of use.

  • Patent number: 9927582
    Abstract: Connector assemblies having an adjustable polarity are described. For example, at least two ferrules may be arranged in a housing of the connector assembly within independent frame plugs in a certain polarity. A top portion of the housing may be removed to allow access to the frame plugs. Accordingly, an installer may open the housing, switch the polarity of the ferrules, and then re-couple the top portion to the housing. In another example, the connector assembly may include a latch that may rotate about the connector assembly from a first polarity position to a second polarity position. The connector assembly may include a compression element that may facilitate the rotation of the latch when the compression element is compressed. In this manner, the latch may be rotated to a different polarity position to allow the connector assembly to be connected to an adapter using a different polarity.

  • Patent number: 9853397
    Abstract: A pluggable module includes a plug body, a deflectable beam, and a tether. A rear end of the plug body is removably receivable in a module cavity of a cage member. The deflectable beam extends from a fixed end to a free end that is spaced apart from the plug body by a clearance gap. The deflectable beam includes a catch feature engaging a complementary catch feature of the cage member to secure the pluggable module in the module cavity. The tether extends through the plug body within a tether channel. A mounting end of the tether is secured to the deflectable beam and a handle of the tether projects beyond the front end of the plug body. Frontward movement of the handle deflects the deflectable beam into the clearance gap for disengaging the catch features to allow removal of the pluggable module from the module cavity.
