    Easily test both Ethernet and USB 3 'Super Speed' connected devices in an RF Shielded test environment ! Latest design includes new LTE cellular bands.

    • Space and cost saving with two interface filters in one housing
    • Both filters pass all data signals while rejecting Cellular, LTE, WiFi and signals above 700 MHz
    • LAN section has all eight RJ-45 lines filtered, useful for LAN as well as other applications
    • Ethernet PoE power passing compatible
    • Patented USB 3 design utilizes new approach to filtering high speed data signals
    • Over 80 db attenuation > 1 GHz with flat response < 480 MHz
    • Rugged machined aluminum construction
    • Balanced filtering for minimal ringing
    • Excellent RF Isolation

    JRE's  LAN-USB 3 Filter consists of two separate and independent filtered interfaces inside of one rugged machined aluminum housing.

    The LAN filter operates at 10/100/1000 speeds using Ethernet compliant low pass filtering which provides exceptional RF shielding on all 8 signal lines, making it compatible with standard Ethernet as well as any other format using an RJ-45 connector. The filter is designed to reject frequencies greater than the Cellular frequencies of 700 MHz while passing data between RJ-45 connected devices such as routers, switches, access points or other Ethernet devices. Since all 8 signal lines are filtered (10/100 Ethernet uses only 4 of the 8 available signal lines while 1000 uses all lines) one can use this filter as an interface to connect various other devices within the test enclosure. Standard RJ-45 jacks are used, so one may wire any signal on to any of the eight lines and pass it across the filter, knowing that anything below 480 MHz will pass and signals above 700 MHz will be attenuated by greater than 70dB. The use of high performance inductors allows a current of up to 250 mA and a DC resistance on any path below 1.5 ohms. Fully Ethernet PoE compatible.

    The JRE USB 3.0 'SuperSpeed' data filter operates on an entirely new principle in data signal filtering. Previous filter designs used low pass filtering on the data lines to attenuate interfering wireless RF signals - however, as data speeds have increased, the data signals fall within the same frequency range as the interfering signals. Thus, simple low pass filtering cannot be used since such a filter will attenuate both the data and the interference!

    Our Patented design uses an innovative application of signal phasing techniques and topology to filter out all RF signals except for the desired data signals. This ability to discriminate between data signals and undesired RF signals is especially valuable when testing at USB Super Speed data rates (since the signaling rate falls within Wireless signal frequencies), or when testing devices where the potential RF interfering frequencies fall within the pass band of a low pass filtered USB interface (such as wireless keyfobs or RFID devices).

    Fully USB compliant, correct enumeration process ensures any test ‘hiccups’ will be properly exchanged between devices, ie: no hang-ups are undetected, a problem when using fiber optic or other such interfaces! The filter 'appears' to the devices as just a one meter long USB 3 cable.

    The USB interface consists of balanced pairs of data lines utilizing proprietary signal phasing techniques along with filtered power and return conductors. Standard USB Type A connectors are used allowing simple and reliable connection to your USB devices. The data line filtering passes the USB Type 1, 2 or 3 'Super Speed' data while providing rejection of 80 dB to undesired RF wireless signals. Included is a USB 3.0 Type A Male to Male jumper cable.
