2.5G/5G BASE-T Multi-Gig Ethernet Transformers

HALO Electronics 2.5G/5G BASE-T Multi-Gig Ethernet Transformers are available in Power over Ethernet (PoE), PoE+, and 4PPoE (+90W) capabilities. These transformers footprint can be interchanged with other 1G, 2.5G, 5G, and 10G HALO transformers. The 2.5G/5G NZ/NZ5 transformers operate at both standard and extended temperature ranges and are designed to meet or exceed the IEEE802.3bz standard. This 2.5G/G series is designed for Power Source Equipment (PSE) and PD PoE applications. These transformers are single port Ethernet isolation modules.
