Attached please find a copy of a technical contribution at the IEEE 25GBASE-T Study Group meeting in May, 2015 Title of Presentation: “ Class Fa (category 7a) Cabling for 25GBASE-T. Channel Test Report” Looking forward to a productive meeting Yakov Belopolsky Manager R&D Stewart Connector | a beL group tel direct: 717-227-7837 , reception: 717-235-7512 email: ybelopolsky@xxxxxxxxxxx 11118 Susquehanna Trail South Glen Rock PA 17327 USA stewartconnector.com From: Belopolsky, Yakov Dear David and George We would like to present a technical contribution at the IEEE 25GBASE-T Study Group meeting in May Title of Presentation: “ Class Fa (category 7a) Cabling for 25GBASE-T. Channel Test Report” Abstract The category 7a cables are used in Class Fa ( IEC/ISO 111801 standard) installations. This contribution provides test data to support the deployment of proposed 25GBASE-T technology over Class Fa cabling, including the existing infrastructure. 10, 30 and 50m long channels utilizing IEC 61076-3-110 connectivity were included in this study. The study utilized commercially available cables and test equipment. The data is presented up to 1200 MHz for NEXT, Return Loss, Insertion Loss , ACR. It is believed that the data reflects typical performance of the installed infrastructure. Additional measurements are underway Time Requested – 15 min Presenter, Affiliation : Yakov Belopolsky , Bel Stewart Co-Author(s), Affiliation(s) – Rich Marowsky , Bel Stewart Yakov Belopolsky Manager R&D Stewart Connector | a beL group tel direct: 717-227-7837 , reception: 717-235-7512 email: ybelopolsky@xxxxxxxxxxx 11118 Susquehanna Trail South Glen Rock PA 17327 USA stewartconnector.com From: Chalupsky, David [mailto:david.chalupsky@xxxxxxxxx] Highlights: Deadline for requesting presentations: 11:59pm Friday May 8, 2015 AOE Deadline for submitting presentations: 11:59pm Tuesday May 12, 2015 AOE Meeting Information The 802.3 interim meeting schedule is posted here: http://events.r20.constantcontact.com/register/event?oeidk=a07ea1509gz0d633853&llr=bqlaqkgab P802.3bq 40GBASE-T task force and the 25GBASE-T study group will meet jointly Monday morning through Tuesday at noon.
