| 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. |
