| Time Period | Brand / Company | Role / Notes |
|---|---|---|
| Late 2000s – 2013 | Nokia Siemens Networks (NSN) | Developed by NSN as a high-capacity packet-optical transport platform, the HiT 7500 targeted backbone and metro-core networks with 100G and beyond scalability. |
| 2013 – 2018 | Coriant | After acquiring NSN’s optical division, Coriant positioned the HiT 7500 as a flexible, high-performance solution for next-gen transport networks, especially in combination with the HiT 7300. |
| 2018 – Early 2020s | Infinera | Inherited via the Coriant acquisition; continued supporting HiT 7500 in existing networks while transitioning customers to Infinera’s advanced optical transport solutions (e.g., ICE and GX Series). |
| Present (Secondary Market) | Independent Resellers & Support Specialists (e.g., Carritech) | Carritech supplies refurbished HiT 7500 equipment, spares, and engineering support to extend the operational life of legacy deployments in metro and core environments. |
