An apparatus () comprising hardware equipment () having hardware components () enclosed by a chassis () having a front side (A) and a rear side (B), and auxiliary equipment () movable within the chassis () along at least one transportation rail () with a non-linear trajectory extending in horizontal plane between a first position at the front side (A) of the chassis () and a second position behind the hardware equipment () at the rear side (B) of the chassis (), wherein a part of the hardware components () is at least temporarily removable from the chassis () or movable within the chassis () to provide space () for moving the auxiliary equipment () within the chassis () along the at least one transportation rail () between the first and second position.

Auxiliary equipment for an electronic apparatus

A systemfor remote sensing of information to be transmitted, said systemcomprising; an optical time-domain reflectometer, OTDR,adapted to transmit an optical probe signal OPS into an optical fiberand to measure a backscattered signal power; and at least one electro-optical signaling unitconnected to said optical fiber, wherein the electro-optical signaling unitis configured to change an attenuation and/or a reflection of the optical probe signal OPS depending on at least one signal provided by one or more signal sourcesin response to the information to be transmitted.

Remote sensing system

A backplane arrangement is provided for an electronic mounting rack with a base backplane with several contact strips, wherein a free space, into which at least one additional backplane can be inserted, is provided on the base backplane.
