Product Overview

The HT304G-TF1 series is a 10 Gigabit physically isolated ethernet switch (optional PoE function) developed independently by H&T Optoelectronics, with four physically isolated 10/100/1000Mbps adaptive RJ45 ports and one 10 Gigabit SFP+ optical port.

The HT304G-TF1 series adopts high-speed TDM technology, and each network occupies a separate gigabit transmission channel, thus completely eliminating mutual crosstalk between the various subsystems in the surveillance system and eliminating the penetration between various types of data such as HD video and the rest of the data.
