Nortel NTN440BB OM3500 OC-48 intermediate-reach (1310nm) shielded SONET interface card.

The Nortel NTN440BB is a shielded OC-48 (2.5Gbit/s SONET) intermediate-reach (IR) interface card for the Nortel OPTera Metro 3500 (OM3500) platform, operating in the 1310nm window; the closely related NTN440BA card in the same series is documented as an OM3500 OC-48 IR 1310 interface, confirming the OC-48/1310nm IR configuration for this part family.

The OM3500 is Nortel’s multiservice DWDM/SONET metro platform supporting DS1 through OC-192 rates, and the OC-48 IR interface gives it a 2.5Gbit/s SONET line card sized for shorter spans than the long-reach variant, typically intra-metro links.

This is a spares/replacement item for OM3500 estates running OC-48 intermediate-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.
