PoE Lan Transformer (integrating Power over Ethernet and network filtering functions)

PoE Lan transformers are core components integrating Power over Ethernet and traditional Lan transformer functions. They enable the simultaneous transmission of data and power over a single cable, eliminating the need for additional wiring and simplifying device deployment. Supporting 10/100/1000Base-T transmission rates and complying with IEEE 802.3 standards as well as 802.3af/at/bt PoE specifications, they feature signal isolation, EMI suppression, low insertion loss, high CMRR and superior insulation performance to ensure the safe and stable operation of equipment.

Such transformers are widely used in scenarios requiring multi-channel Ethernet connections and Power over Ethernet (PoE), including switches, routers, servers and industrial equipment. They enable simultaneous transmission of data and power over a single network cable, simplifying device deployment and cabling management.

Trxcom's PoE Lan transformers cover single, dual and four-port specifications, feature SMT and through-hole mounting packages, and support customization. They are compatible with network devices in multiple scenarios such as consumer and industrial grade, and ensure stable and reliable performance through rigorous testing.

FAQs About Common Issues of PoE Lan Transformers

Q: What is a PoE Lan transformer? What are the differences from ordinary LAN transformers?

A: It is a dedicated transformer integrated with PoE power supply function, which can transmit data and power simultaneously and comply with PoE standards. Ordinary LAN transformers are only responsible for data transmission without power supply capability.

Q: Which PoE standards are supported? What are the differences in power?

A: Trxcom supports IEEE 802.3af (15.4W), 802.3at (30W) and 802.3bt (60~90W), which are compatible with low-power, medium-power and high-power devices respectively.

Q: What are the core functions?

A: The core functions include four major aspects: signal isolation and high-voltage protection, EMI suppression, data transmission assurance, and PoE power transmission.
