Bel Magnetic Introduces New MagJacks for Higher Power Ethernet
The 4-port model can be used in either power source equipment or powered devices. The 2-port model is well suited for
network Interface cards and products requiring smaller boxes.
Both units are backward compatible to slower speeds and lower
powers using industry standard footprints and pinouts.
Bel Magnetic Solutions, part of the Bel group of companies,
manufactures integrated connector modules, power transformers, power inductors and discrete components. The parent
company, based in Jersey City, NJ, designs, manufactures
and markets a broad array of products that power, protect and
connect electronic circuits primarily used in the networking,
telecommunications, computing, military, aerospace, transportation and broadcasting industries.
Responding to the increasing high-power requirements for
Power-over-Ethernet (PoE) connectivity, Bel Magnetic Solutions has introduced two new models to its line of MagJack
integrated connector modules.

The products, a 4-port model and a 2-port, use two types of
wire-wound magnetics, explained John Hess, product manager. "The first type is a toroidal common-mode choke. We
wrap magnetic wire around the core to create inductance that
at higher frequencies acts as an attenuator to common-mode
noise that may be on the differential pair."
"The second is a toroidal 1:1 isolation transformer where we
are creating 1500Vrms of isolation between a primary side and
secondary side of the transformer while maintaining the proper
impedance. This transformer also has a center tap on the
secondary side that we use in pairs to transmit or receive power
over the data lines of an ethernet cable."
The units are designed for telecom and networking applications
including new 5G requirements and large-screen video display
units. They offer maximum power of 100W or 1A over standard
Ethernet cable. Customers can implement 100W PoE to double
the amount of power their products manage over existing applications, while operating at Gigabit Ethernet speeds. They
provide the capability of transmitting or receiving 0 to 100W of
power per port over all four pairs within the Ethernet cable while
maintaining the bandwidth of the Gigabit Ethernet signal.
