A driving apparatus and a valve including the same. The driving apparatus senses a pressure of a fluid medium and generates a driving force. The driving apparatus includes: a drive shaft, a sensing device, a limiting device, a support body, and a protruding member. The limiting device includes a groove, and the protruding member is engaged in the groove. The limiting device can thus automatically limit the rotation of the drive shaft, so as to avoid damaging the sensing device, thereby facilitating maintenance and installation of the valve.

An optical transceiver system includes an optical transceiver module configured to be locked to cage in a host electronic equipment and a key configured to remove the optical transceiver module from the cage, wherein the key comprises two fingers configured to be inserted into the cage and unlock optical transceiver module from the cage.

Optical transceiver having improved unlocking mechanism

An optical transceiver module includes a housing comprising a first end and a second end, an electrical interface associated with the first end and an optical interface associated with the second end. The electrical interface is adapted to be locked into a receiving cage. The optical interface is adapted to be connected with one or more optical transceiver components. The optical transceiver module includes a locating mechanism that restrains the one or more optical transceiver components. The optical transceiver module also includes a locking mechanism that can lock the optical transceiver module to a receiving cage. The optical transceiver module further includes an automatic-restoring unlocking mechanism comprising a sliding plate, an unlocking lever, and a restoration spring, wherein the automatic restoring unlocking mechanism automatically restores the sliding plate to the normal position after the optical transceiver module is unlocked from the receiving cage.
