In A system for mounting an electronic device on a device rack is provided. The device rack is for supporting a plurality of the electronic devices spaced along the rack in a first direction of the system. The system comprises: the electronic device; and a bracket for mounting the electronic device in a device rack, the bracket comprising: a first coupler configured to couple the bracket to the electronic device; a second coupler configured to couple the bracket to the device rack; and a bracket body comprising: a first arm extending between the first coupler and the second coupler; and a second arm extending between the first coupler and the second coupler, wherein the first arm and second arm are spaced apart to define an opening through which one or more cables and/or fibres connected to the electronic device can extend.

System for rack mountable electronic devices

There is provided an interface module (), comprising: an interface () for connection with a signal connector (); a cage () for guiding the signal connector towards the interface; and a heat sink (). The cage () comprises a cage portion () that is configured to move from a first position to a second position upon insertion of the signal connector () into the cage. In the first position, the cage portion is not in thermal contact with the heat sink; when in the second position, the cage portion is in thermal contact with the heat sink. The cage portion () comprises one or more apertures ().

Connector system

There is provided a security system for use at an enclosure containing one or more passive components of an optical communication link. The security system comprises a sensor configured to detect a physical breach of the enclosure, and an optical alert signal generator coupled to the optical communication link. The optical alert signal generator is self-powered, and configured to generate an optical alert signal and transmit the optical alert signal through the optical communication link when a physical breach of the enclosure is detected by the sensor. The optical alert signal is detectable at an entity external to the enclosure and connected to the optical communication link.

Security system

A sealing unit for a cabinet containing optical components. A gasket defines a plurality of apertures configured to provide a seal around a plurality of optical fiber cables, wherein the gasket has an interior side intended to face the interior of the cabinet and an exterior side intended to face an exterior of the cabinet. A first retaining device is located on the interior side of the gasket, and a second retaining device is located on the exterior side of the gasket. The first and second retaining devices each include a plurality of channels, wherein each channel is aligned with a respective aperture of the gasket and each channel is configured to receive one of the plurality of optical fiber cables. Each channel has a profile defined by a plurality of protruding surfaces configured to restrain longitudinal movement of an optical fiber cable received therein.

An optical assembly has a number of optical fibers which terminate at connectors which connect to short lengths of optical fibers which connect, in turn, to an optical back plane mounted within a housing. The connectors are withdrawn from the housing for inspection. A plurality of movable guides is provided for the short fibers to determine a number of optical paths which remain of constant length as the connectors are withdrawn from the housing.

Optical assembly

An equipment assembly includes a housing and a sub-unit each having a large array of electrical contacts which mate when the sub-unit is inserted into the housing. The sub-unit has a plurality of threaded bolts which extend through the sub-unit to engage with cooperating threaded nuts secured to the housing. The plurality of bolts is linked together mechanically, so that all bolts engage simultaneously with their respective nuts, and draw the sub-unit into engagement with the housing as the bolts are rotated.
