DOCSIS Management & Engineering (~8 Years)

After working for several Multi-Service Internet Providers between 2013 to 2018, and 2021 to 2024, I have a fair background in understand RF Theory, RF Systems, RF over Glass (RFoG), Hybrid Fiber/Cable systems (HFC), modem firmware, and associated DHCP/IP Subnetting. TFTP, troubleshooting EFI, and to an extent DOCSIS MIBS were included as part of the work required. This comes with an understanding of the fragility of systems heavy with fiber optics.

Whether your cable plant is broadcast or narrowcast, Motorola, Cisco, Casa, or Arris CMTS, I hold experience with each type of system.

I am interested in positions that allow DOCSIS engineering remotely. Most of the work that I have done in the DOCSIS realm has been to remote locations, generally speaking. This page is for DOCSIS/Cable related information only.
