Integrated Magnetic Jacks that support PoE and Modular Jacks that support Cat3, Cat5, Cat6,1G,2.5G, and 10G.single-port and multi-port, with transformer and without a transformer. The magnetic receptacle incorporates a transformer into the standard RJ45 connector. these integrated magnetic components, resistors, and/or capacitors filter common mode noise to provide signal integrity, protect the PHY chip, provide DC isolation and provide low mode switching. Magnetic sockets are available in Power over Ethernet (PoE) versions that functionally support PoE while allowing customers to manage power. Magnetic sockets support Fast Ethernet (10/100), Gigabit Ethernet, and 10 Gigabit Ethernet applications.
