Abstract: An optical fiber module rack system includes a rack including multiple accommodation chambers, opposing first and second sliding grooves located in each accommodation chamber, and a stop block located at each of opposing front and rear ends of each first sliding groove, and optical fiber storage boxes each including a box body mounted in one respective accommodation chamber, a first optical fiber module and second optical fiber module mounted in opposing front and rear sides of box body and connected together, two guide rails located at two opposite lateral sidewalls of box body and respectively coupled to first sliding groove and second sliding groove of respective accommodation chamber, two elastic retainer strips respectively extended from opposite ends of one guide rail and provided with a respective hook block for engagement with one respective stop block, and elongated press member extended from other guide rail for pressing by external force to disengage hook blocks from respective stop blocks for allo

Abstract: The present disclosure illustrates to a fiber module rack system in which a rack includes receiving spaces which each is formed by two frame plates of a base panel. Shell bodies of fiber optic cassettes are mounted in the receiving spaces, and a fiber module is disposed at a front part of the shell body, and a resilient locking member is disposed between the sliding track and at least one side of the shell body, so that the user can quickly and easily dismount the fiber optic cassettes from the rack without using tool.

Abstract: A fiber channel-interchangeable fiber optic connector includes an adapter, two connectors respectively rotatably mounted in respective axle holes at the front side of the adapter, a sub-assembly detachably attached to the adapter to stop the connectors from rotation and hold down the connectors in position, and a cable inserted through the sub-assembly and mounted in the adapter with two optical-fiber cores therein respectively inserted into ferrules of the connectors. Detaching the sub-assembly from the adapter allows rotation of the connectors and the sub-assembly through 180-degrees angle relative to the adapter to interchange the fiber channels.

Abstract: An improved structure of a laser indicator includes an outer tube, a cover cap, a focus adjusting device, an optical lens, and a circuit board having a laser diode disposed thereon. The outer tube and the cover cap are joined to form a rod-shaped indicator housing. The optical lens and the laser diode are provided inside the focus adjusting device, which is comprised of an inner cover and an outer cover working in conjunction with a metallic spring. The laser diode is fittingly disposed inside the inner cover, while the outer cover is screwably connected to the outer cover. The spring is disposed between the inner cover and the optical lens. One end of the outer cover is screwably coupled to the cover cap, while the other end thereof forms a smooth holding surface to facilitate turning of the outer cover in focus adjustment.
