An amplifier module for radio frequency signal circuits includes an electrically conductive housing. Two coax connectors are electrically linked to an amplifier circuit contained within the module. A separate transformer is external to the module. Both the module and the external transformer are mountable to a chassis frame. Other modules are usable in the system in addition to the amplifier module. The transformer can be wall mounted to the chassis frame, or the transformer can be internal to a module which also mounts to the chassis frame.

RF circuit module and chassis including amplifier

A telecommunications apparatus for use with a plug having at least first, second and third pins. The telecommunications apparatus includes a plug connector for receiving the plug. The plug connector includes at least first, second and third electrical contacts for electrically contacting the first, second and third pins, respectively, when the plug is inserted in the plug connector. The plug connector also includes an electrical by-pass pathway that: i) electrically connects the first and second electrical contacts when the plug is fully removed from the plug connector such that a signal can enter the plug connector through the first contact, pass through the by-pass pathway to the second contact, and exit the plug connector through the second contact; and ii) does not electrically connect the first and second electrical contacts when the plug is fully inserted within the plug connector such that a signal can enter the plug connector through the first contact, pass through the plug to the second contact, and exit the plug connector through the second contact.

Plug connector for cable television network and method of use

A telecommunications chassis is disclosed herein. The chassis includes a housing defining a front end, a rear end and an interior, the chassis housing telecommunications equipment within the interior, cables connected to the telecommunications equipment configured to exit through the rear end. The housing is configured for mounting to a telecommunications rack and being movable relative to the rack between a closed position and an open position. A cable management structure is mounted between the housing and the rack, the cable management structure configured to move the cables exiting the rear of the housing upwardly, out of the way of the housing when the housing is moved from the open position toward the closed position.

High density telecommunications chassis with cable management structure

A module for containing a circuit is provided that attenuates emitted signals without the use of a cover. The module includes a housing and a receptacle. The housing has a front having a certain thickness and the receptacle is accessible from the front of the housing. The receptacle is shaped to receive a circuit component and forms a waveguide.

EMI shielded module

A cable management system having as an integral part of the device needing cable management a slot arrangement that receives and holds cables. A lock bar closes the slot arrangement such that the cables are trapped in the slot arrangement. Methods of managing cable include the lock bar and slot arrangement.

Cable management apparatus

An amplifier switch controller is provided for use in a headend cable transmission system having first and second amplifiers and amplifier input and output paths connected to one of the first and second amplifiers, which becomes the currently activated amplifier. The amplifier switch controller comprises an input sampler for sampling a combined signal on the input signal path and measuring an input signal level. The amplifier switch controller also comprises an output sampler for sampling the amplified combined signal on the output signal path and measuring an output signal level. A program means receives the input and output signal levels and determines whether the currently activated amplifier is not functioning properly. If it is not functioning properly, the program means generates a control signal to a switch. In response to the control signals, the switch disconnects the input and output signal paths from the currently activated amplifier and connects each of the input and output signal paths to the other one of the first and second amplifiers.
