Nortel NTN440DB OM3500 OC-48 long-reach (1550nm) shielded SONET interface card.

The Nortel NTN440DB is a shielded OC-48 (2.5Gbit/s SONET) long-reach interface card for the Nortel OPTera Metro 3500 (OM3500) platform, operating at 1550nm, confirmed against manufacturer/reseller documentation for this exact part number as an OC-48 LR 1550 interface.

The OM3500 is Nortel’s multiservice DWDM/SONET metro platform supporting DS1 through OC-192 rates, and the OC-48 LR interface gives it a 2.5Gbit/s SONET line card with long-reach optics for spans that need more distance than a standard-reach interface can cover.

This is a spares/replacement item for OM3500 estates running OC-48 long-reach interfaces. Tech-Star (UK-based, shipped worldwide) checks every interface card before it ships. Get in touch to confirm compatibility with your specific OM3500 shelf.
