Who We Are

Dawn Technology Limited was established in Hong Kong in 2005 and moved to the United Kingdom in 2020. We specialise in designing and producing high-precision electronic devices and have a strong reputation as a pioneer in the electronics industry.
Our effe Series of optical isolators is designed to block network noise before it reaches your audio or video streamer. The range includes three models: the effe-01 All-in-One Isolator, the effe-02 Single-Port Ethernet-to-SFP Converter and the effe-03 3-Port SFP Switch & Converter. Every unit is designed, assembled and tested in the UK, and we sell directly to our customers with a 30-day home trial.
