| Late 1990s – 2009 | Nortel Networks | Developed and marketed as the **Optera** series, including platforms like Optera Metro 5100/5200, Optera Connect, and TN Series (Transport Network). These provided optical switching, WDM, SONET/SDH, and metro/core transport capabilities. |
| 2009 – Present | Ciena | Ciena acquired Nortel’s Metro Ethernet Networks (MEN) business in 2009. While Nortel’s OME 6500 was actively integrated, most Optera and TN systems were gradually phased out, with limited long-term support and migration paths offered. |
| Present (Legacy Support) | Distribuidores independientes y especialistas en asistencia (por ejemplo, Carritech) | Carritech and similar companies provide continued support, refurbished equipment, and expert services for Nortel Optera and TN platforms in legacy optical transport environments. |
