The waveguide tube is the special designed tube for optic fibre enter into the RF shielding room or chamber. With the two half parts design, it is very easy to fit the optic fibre into the tube. The length and hole diameter is calculated carefully, there is a good performance under the 40GHz Frequency. It is available to work with the other shielding frequency spots.

As common condition, the CATEGORY 5 LAN line is forbidden to connect into the shielding room or enclosure. It will affect the shielding room or enclosure performance deeply. The WaveGuide Tube is a new fitting to fit this condition. With the Optical Fiber to RJ 45 converter and optical fiber, it is available to connect the computer inside the shielding room or enclosure with the outside LAN. There is not affect for the shielding performance.
