Fiber optic equipment that supports independently translatable fiber optic modules and/or fiber optic equipment trays containing one or more fiber optic modules is disclosed. In some embodiments, one or more fiber optic modules are disposed in a plurality of independently translatable fiber optic equipment trays which are received in a tray guide system. In this manner, each fiber optic equipment tray is independently translatable within the guide system. One or more fiber optic modules may also be disposed in one or more module guides disposed in the fiber optic equipment trays to allow each fiber optic module to translate independently of other fiber optic modules in the same fiber optic equipment tray. In other embodiments, a plurality of fiber optic modules are disposed in a module guide system disposed in the fiber optic equipment that translate independently of other fiber optic modules disposed within the module guide system.

High-connection density and bandwidth fiber optic apparatuses and related equipment and methods are disclosed. In certain embodiments, fiber optic apparatuses are provided and comprise a chassis defining one or more U space fiber optic equipment units. At least one of the one or more U space fiber optic equipment units may be configured to support particular fiber optic connection densities and bandwidths in a given 1-U space. The fiber optic connection densities and bandwidths may be supported by one or more fiber optic components, including but not limited to fiber optic adapters and fiber optic connectors, including but not limited to simplex, duplex, and other multi-fiber fiber optic components. The fiber optic components may also be disposed in fiber optic modules, fiber optic patch panels, or other types of fiber optic equipment.

High density and bandwidth fiber optic apparatuses and related equipment and methods

A network tap device that is configured for operation in a copper Gigabit Ethernet communications network using a power-over-Ethernet (“POE”) electrical supply is disclosed. In one embodiment, a network tap device powered by a POE supply is disclosed, comprising first and second network ports that are configured with receptacles for receiving communication cables. The communication cables are configured to carry both data signals and the POE supply to and from the network tap device. The network tap device further includes first and second tap ports that connect with additional communication cables to a monitoring device. The network tap device also includes control and regulation circuitry that is configured to receive the POE supply from the communication cables via the network ports and to enable components of the network tap device to be operated by the POE supply.

Network tap device powered by power over ethernet

The present invention provides for network taps capable of connecting to a plurality of communication cables. The network taps provide one or more levels of multiplexers which allow network data signals from a particular communication cable to be delivered to an attached device in order to monitor the activity of the communication cable. The network taps also include integrated circuitry which control the various functions and components of the network tap. Embodiments of the network taps include ones in which network data signals from each communication cable are communicated to the integrated circuitry to allow the integrated circuitry to monitor across all communication cables; network taps having switches to provide for different port configurations; network taps having switches which allow attached devices to transmit data into the network tap; network taps having ports which allow for cascade configurations; and network taps having integrated circuitry which can communicate with a remote client device to provide additional functionality.

Multi-port network tap

A network data monitoring device provides for the flexible, programmable port-to-multi-port steering of data packet traffic between network port pairs, with tap data streams being directed to any of a plurality of monitor ports. The network data monitoring device is constructed utilizing one or more switching integrated circuits programmed to disable layer-2 routing and impose port-to-multiport data packet steering. Physical layer protocol encoding/decoding circuits enable connectivity to physical network media connectors though a system of fail-safe relays. A system controller, preferably implemented by a microprocessor, is connected to all switching integrated circuits and relays for configuration, status and control. Hardware-based logic selectively in complement to the switching integrated circuits provides for the programmable filtering, modification and programmable steering of data packets through the device.

Ethernet switch-based network monitoring system and methods

A tap device comprises a network entry connection, a network exit connection, and a network interconnection path there between. A high impedance tap circuit is electrically connected to the network connection path, and comprises an isolation transformer and active buffer element. Advantageously, a power interruption to said tap circuit does not affect network communications.
