Provided is an RF heat dissipation plastic. The heat dissipation plastic according to one embodiment of the present invention is implemented by including: a polymer matrix comprising a base resin; and hollow first fillers dispersed in the polymer matrix. Accordingly, the RF heat dissipation plastic has the advantageous effect of simultaneously exhibiting low permittivity and excellent mechanical strength due to the hollow fillers included therein. In addition, despite the low permittivity and excellent mechanical strength designed for the RF heat dissipation plastic, the RF heat dissipation plastic exhibits excellent heat dissipation performance due to non-hollow fillers included therein, which exhibit heat dissipation performance. According to the present invention, the RF heat dissipation plastic exhibiting the low permittivity and the excellent mechanical strength and heat dissipation performance can minimize performance degradation or functional loss of a repeater cabinet which may be affected by transmission and reception of high-frequency band signals according to permittivity, and thus can be widely applied to various products across all industries.

The invention relates to a switch cabinet arrangement with at least one IT rack or switch cabinet housing and with at least one cooling device, which has an air-liquid heat exchanger for cooling components accommodated in the IT rack or switch cabinet housing with cooled air, wherein the air-liquid heat exchanger comprises a first flow for cooled liquid and a first return for heated liquid, wherein the cooling device comprises a liquid-liquid heat exchanger, to the second flow of which the first return of the air-liquid heat exchanger is connected. A corresponding method is further described.

A communication system may include a first chassis having first and second side walls and adapted to slidably receive therein a plurality of cassettes. A first cable hanger assembly may have a first side edge hingedly coupled to the first side wall of the first chassis, the first cable hanger assembly including a plurality of first hangers adapted to support cables thereon. An axis of rotation of the first cable hanger assembly may be substantially orthogonal to a direction in which the plurality of cassettes are slideable. The cable hanger assembly may be rotatable from a first position to a second position so that during rotation from the first position to the second position, the plurality of first hangers move toward front faces of the plurality of cassettes.

The present disclosure describes a telecommunications equipment mount. The telecommunications equipment mount includes a stabilization frame having a plurality of lower rails, a plurality of vertical rails, and a plurality of upper rails, the lower, vertical, and upper rails forming a top, a bottom, and at least sides of the stabilization frame to define an open interior cavity; at least one mounting member extending outwardly from, and perpendicular to, one of the sides of the stabilization frame a distance; at least one brace member coupled to the stabilization frame and configured to support the at least one mounting member; and at least one mounting pipe secured to the at least one mounting member. The stabilization frame is configured to ballast the mount on a mounting structure when telecommunications equipment is secured to the at least one mounting pipe. Telecommunications equipment mount assemblies are also described herein.

A bladed chassis system facilitates installation of the bladed chassis system and replacement of the blades at the chassis. Blades can be inserted and removed from the front and/or the rear of the bladed chassis system at the discretion of the user. Blades can be moved between discrete positions. In examples, blades can be one-handedly released from the chassis to allow movement between discrete positions. In examples, accidental movement past a discrete position is inhibited. Accidental removal of the blades from the chassis is inhibited. The chassis and blades cooperate to manage the optical fiber cables routed through a cable port in the chassis to the blades.

In some implementations, a network device includes a housing and a set of switch cards within the housing and including a first set of connectors. A set of line cards within the housing includes a second set of connectors. The set of line cards are oriented orthogonally to the set of switch cards. A first set of power supplies and a second set of power supplies are in the housing. A midplane includes a plurality of circuit board assemblies arranged within the housing between the set of line cards and the first and second sets of power supplies to allow air to flow through the set of line cards to the set of switch cards, first set of power supplies, and second set of power supplies.

In accordance with some aspects of the disclosure, a modular telecommunications patch panel system is shown and described. The panel can include a mounting frame extending between a first end and a second end, the mounting frame defining a plurality of apertures for receiving telecommunications components, a first mounting ear forming a snap-fit connection with the mounting frame first end, in a first orientation, and a second mounting ear, identical to the first mounting ear, forming a snap-fit connection with the mounting frame second end, in a second orientation.

A system for cabling infrastructure that includes at least one port, at least one shutter, at least one sensor and a gateway is provided. The port is configured to be selectively coupled to a connector. Each shutter is configured to have an open state that allows access to an associated port and a closed state that covers the port. Each sensor is configured to sense the open state and the closed state of an associated shutter and generate shutter state signals that include information relating to a current sensed state of the associated shutter and an identification of a port that is associated with the associated shutter. The gateway is in wireless communication with each sensor to receive the shutter state signals. The gateway is configured to communicate the shutter state signals that indicate a change in a state of an associated shutter to a remote location.
