Nortel NTKD11AA: TN-1X STM-1 optical tributary unit. Confirm the optics and release against your shelf before ordering.

The Nortel NTKD11AA is an STM-1 optical tributary unit for the TN-1X, Nortel’s STM-1 add and drop multiplexer. It terminates an optical STM-1 tributary on the shelf, whether that is a spur out to a customer site or a link across to another cluster of multiplexers. Release and revision suffixes vary within this part number, so tell us the system it is going into and we will confirm the exact unit we hold.

The TN-1X is Nortel’s STM-1 add and drop multiplexer, installed widely across UK and European SDH access networks. A node is built up from a subrack of plug-in units: the subrack controller, a mixed payload manager, 2 Mbit/s and 34/45 Mbit/s tributary units, STM-1 optical and electrical tributaries, traffic access modules and a power supply. Keeping one in service means sourcing the exact unit rather than replacing the system.

Tell us what you are replacing and we will inspect the stock item, read the label and confirm the release before we quote. Tech-Star (UK-based, shipped worldwide) holds Nortel equipment for maintenance and expansion projects. Please contact our sales team for availability, condition and pricing.
