AE-C5E-OTD is an Outdoor Cat5e cable built in order to prevent the twisted pair from being broken during the movement, with the outer PE having a certain toughness. At the same time, in order to facilitate the manufacturing and connection of the connector, the copper wire can neither be too soft nor too hard. If it’s too soft, it is difficult to make the connector. If it’s too hard, it will easily break the connector. And the double sheath of AE-C5E-OTD solves the technical problems of the weak current system.
