DOCSIS 3.1 – 10 Gbps over Coaxial Cable – Overview and OFDM Profile Optimizations

Time & Date: 4:30 pm – 5:30 pm, February 18th, 2016
EME 1151, UBC, Okanagan Campus, Kelowna, BC

Talk Abstract: DOCSIS (Data over Cable Service Interface Specification) 3.1 is a recently developed standard for delivery of high speed data 
over coaxial cable with speeds up to 10 Gbps.  In this talk, presenters from Vecima Networks, a Victoria and Saskatoon-based 
equipment manufacturer, will provide an overview of DOCSIS 3.1 physical layer and discuss research related to optimization of 
OFDM parameters to maximize system performance within sets of modems in a cable TV serving area.
