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

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.

Sealing unit for optical fiber cable cabinet

An electronic circuit board including a plurality of electronic components mounted on the electronic circuit board and a plurality of electricity conductive paths for connecting the electronic components. The electronic circuit board further includes a plurality of electric connectors arranged in a bank along an edge of the electronic circuit board, wherein each one of the plurality of electric connectors is formed from the material of the board as a finger projecting outside the electronic circuit board. In line with either edge of each one of the electric connectors the electronic circuit board has a cut forming a gap and projecting into the board.

Flexible connectors for expansion board

An optical add/drop device () comprising: a common port (); an add port (); a first wavelength selective optical filter () configured to: receive an optical signal at an add wavelength from the add port and transmit said optical signal at the add wavelength towards the common port; and receive optical signals from the common port and reflect optical signals not at the add wavelength; a second wavelength selective optical filter () configured to receive said optical signals from the common port reflected by the first wavelength selective optical filter and transmit an optical signal at a drop wavelength, different to the add wavelength; a drop port (); and an optical waveguide () configured receive said optical signal at the drop wavelength transmitted by the second wavelength selective optical filter and route said optical signal to the drop port.

Optical add/drop device and assembly, and communications network node

A method of dispersion compensation for an optical link includes establishing communication using a first symbol rate over the optical link, determining a dispersion compensation for the optical link based on the communication at the first symbol rate, and establishing communication using a second symbol rate over the optical link using the determined dispersion compensation, wherein the second symbol rate is higher than the first symbol rate.

Dispersion compensation

There is provided an interface module, having an interface for connection with a signal connector, a cage for guiding the signal connector towards the interface and a heat sink. The cage includes 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.
