ABSTRACT:
A dustproof transceiver includes a transceiver body, a first dustproof cover and a second dustproof cover. The transceiver body has an opening to receive an optical fiber connector. The first dustproof cover is pivotally connected on the transceiver body to swivel and shelter a part of the opening. The second dustproof cover slides on the transceiver body to shelter the remaining part of the opening. A spring is secured to the transceiver body at one end and secured to the second dustproof cover at an opposite end. A rebounding member has two spiral springs, two securing ends and a securing section linking the two spiral springs. The two securing ends are respectively coupled to the transceiver body and the securing section is coupled to the first dustproof cover such that the rebounding member exerts a force on the first dustproof cover to shelter the part of the opening.
