Platform history

Ownership & marketing history

Time Period Brand / Company Role / Notes
Early 2000s – 2013 Tellabs Developed and marketed the Tellabs 8100 Managed Access System as a multiservice access and aggregation platform, supporting Ethernet, TDM, and SDH/SONET for business and mobile backhaul networks.
2013 – 2014 Tellabs (Sun Capital Partners) Continued support and limited new deployments under private equity ownership. The 8100 platform was retained as part of the legacy access product line.
2014 – 2018 Coriant The 8100 system was integrated into Coriant’s access and aggregation solutions after Tellabs’ optical transport business was merged into Coriant.
2018 – Early 2020s Infinera Infinera acquired Coriant and provided continued support for 8100 systems under contract. Strategic focus shifted to IP and optical convergence on newer platforms.
Present (Secondary Market) Independent Resellers & Support Specialists (e.g., Carritech) Carritech supports the Tellabs 8100 platform with spare parts, refurbishment, and technical assistance for customers operating legacy networks.
