Did this set bought by an Access Point (Sophos AP10) over the network to supply electricity. It works with a 10m long network cable problems. There are definitely "only" max. 100Mbit / s via the cable set, as only 4 wires for data transfer can be used, the others will be used for the power supply. The set makes a good quality impression: All plugs and sockets fit very well and do not wobble. Can only recommend this product!
