Pass up to six fiber optic cables into the RF test chamber without having to remove connectors. Simply remove the Allen head screw and the machined insert and pass through your cables. Reinsert the machined insert and tighten using the Allen head screw. Shielding isolation of greater than 130 dB to 18 GHz and still provides 60 dB at 28 GHz.
For use only with fiber optic cables, if conductive cables or wires are passed through the portal, the shielding isolation of the test chamber will (obviously!) be severely degraded. Understand that any wired connection to a device inside a test chamber must be suitably filtered in order to maintain the shielding isolation of the test enclosure.
