Description:
The Nortel NTEU23AA is a legacy optical transport module originally designed for use in Nortel OPTera Metro 4150 SDH (Synchronous Digital Hierarchy) transport platforms. It functions as an STM‑4 (approx. 622 Mbps) optical aggregate card, providing short‑haul 1310 nm optical transmission aggregation in metro and regional network environments. This card was installed inside a chassis alongside other line and tributary modules to support high‑order traffic aggregation and transport in legacy optical networks.
