ETS Ethernet Cable Clamp Testers (CC-101/102/109) are designed to let users inject a common mode current into CAT5e, CAT6A and CAT7 cables to test gigabit Ethernet for the common mode noise. The CC-101 and CC-102 have (6) thumb-bolts allowing the release of the unit halves for cable insertion for testing purposes. The CC-109 has 4 spring latches for quick and easy test set ups.
More details from ETS (www.etslan.com):
The Ethernet Cable Clamps (CC-101/CC-102/CC-109) are used in the common-mode noise rejection test of the IEEE Standard 40.6.1.3.3, which is used to determine the sensitivity of the 1000BASE-T or 10GBASE-T receiver to common-noise from the link segment. This specification is provided to limit the sensitivity of the PMA receiver to common-mode noise from the cabling system. All units can test 1 – 10 Gigabits.
Designed by IEEE engineers, and built according to the 802.3 requirements, these unique Cable Clamp Ethernet Testers are made in the USA and only by ETS.
