Abstract: A connection housing has a main pair and a secondary pair of electrical contacts on a printed circuit board (22), each pair having a first (241, 242) and a second (251, 252) electrical contact. A first set (261) of conductive tracks electrically couples the first contacts of the main (231) and secondary (232) pairs, and a second set (262) of tracks electrically couples the second contacts of the main and secondary pairs. The contacts of the main pair are two perforation or insulation displacement contacts receiving transversally and directly connecting two insulated conductors of a same main single-pair Ethernet cable (1a) entering and exiting from the housing through two main ways (271, 272) for access to the housing. The contacts of the secondary pair (232) electrically connect two insulated conductors of a same secondary Ethernet cable (1b) linked through a secondary way (273) for access to the housing.

Abstract: A system (10) for monitoring a network is formed by a plurality of devices (12), each device (12) of the plurality of devices having at least one status sensor (13) measuring at least one physical parameter of the device (12). The system (10) further has a monitoring platform (14) communicating with the at least one status sensor (13) by means of a telecommunications network (16).

Abstract: An electromagnetic cable shielding is provided having a braid including a plurality of wires in contact with one another. At least one wire has an oval cross section.
