Description:
The OPTA3500 Shelf with I/O (often referenced under distributor SKUs such as NTN476AH-Sxx, e.g., NTN476AH-S03/08) is a modular shelf chassis assembly for the Nortel OPTera Metro 3500 optical transport system — a carrier-grade multiservice platform used in metropolitan and long-haul DWDM/CWDM networks. This shelf serves as the foundational chassis for housing optical line cards, interface cards, circuit packs, and transponder modules within the OPTera Metro 3500 family. It incorporates front access I/O connections and is designed to support metro transport functions such as wavelength multiplexing, add/drop functionality, and high-capacity optical aggregation.
