CommScope Prototype Category 8 Short Cabling Link measured two ways
1m cord
3m Cable
1m cord
Mod Jack

Through ICM from two different manufacturers as PHY chip to PHY chip:
With end plugs removed as measured for TIA compliance:
CommScope Test Head
CommScope Channel
7/4/2015 3 CommScope - 802.3 bq by Submission
Side by side Insertion Loss and Return Loss
Small amount of additional RL
Expected BALUN Loss
Some Additional ILD
Short Channel – Significant RL
Short Channel – Low IL and strong reflections
7/4/2015 4 CommScope - 802.3 bq by Submission
Side by side NEXT and FEXT
Short Channel – Significant Connector NEXT
Manageable Additional FEXT
Manageable Additional NEXT
Conclusions:
• Excellent results in support of ongoing work on 802.3bq and PN-568-C.2-1 demonstrated with critical short channel
• 4 primary cabling performance parameters significantly maintained by the ICM
• Demonstrated compatibility with independent prototype designs from 3 different suppliers
