Ethernet Transformers are SMD communication magnetic transformers that range from 10Mbit/s to 10G. Ethernet transformer modules are optimized for all major LAN transceivers. Ethernet transformer modules provide electrical circuit isolation that meets IEEE 802.3 while maintaining signal integrity needed for the most demanding applications. Ethernet transformer modules include a common mode choke for noise attenuation matched to the specified transceiver and are designed for extended temperature range (-40°C to +85°C) applications. Ethernet transformer modules support the continued convergence of voice and data networking, computing, and storage traffic in the enterprise and data centre with insertion loss, return loss, and crosstalk performance and reliability. In Ethernet LAN the power is connected via transformers with centre tap on pins 1-2 and 3-6 so that these are invisible for the data stream. Ethernet transformers are used for addition of magnetics and a connector while connecting Ethernet module to a wired Ethernet.

Ethernet Transformer Market: Drivers and Challenges

Ethernet transformer market used for applications such as connectivity is expected to grow at good pace. The growth in the market of VoIP phones is also helping the market to grow. Ethernet transformer helps in isolation of the power and signal conditioning while the data or voice is transmitted over the Ethernet. Ethernet transformer also helps in turning a pair of single ended drives into a differential signal
