Abstract: A backplane comprises a support structure which has a plurality of apertures defined along it, the apertures communicating with an optical path extending along the structure. An equipment module has a connector which carries optical devices, the connector engaging with one of the apertures so as to provide mechanical support for the module and to put optical devices into communication with the optical path. Preferably the backplane also has electrical conductors which couple with contact lobes on the connector for powering the module. Preferably the optical devices are moveable between shielded and operable positions.

Abstract: A tool for use in manipulating telecommunications modules comprises a housing having a grip, engagement means for engaging with a module so as to securely grasp the module and a transmitter/receiver unit for transmitting signals to and receiving information from the module. Information received from the module is displayed on the tool. The tool also has a control for allowing a user to request decommissioning of the module to which it is engaged, the tool being arranged to receive a reply from a module indicating that decommissioning is complete. Preferably an interlock mechanism couples an unlocking control on the tool to a key, the interlock inhibiting key until receiving the reply from the module indicating that decommissioning is complete. The tool can also be used to configure a module.
