Nokia C8821: FDAD add-drop unit for Nokia SDH/PDH multiplexer platforms.

The Nokia C8821 is an FDAD card, a fibre add-drop plug-in unit from Nokia’s legacy optical transmission equipment range. Add-drop cards of this type sit within an add-drop multiplexer shelf and handle the insertion and extraction (“add” and “drop”) of traffic at an intermediate site on a transmission ring or point-to-point link, without needing to fully terminate the whole path.

The “FD” prefix in this family is consistent with a fibre-side add-drop function, working alongside the shelf’s line and tributary cards to route the correct portion of traffic on and off the network at that node. Add-drop units are a core building block of ring-based transmission networks, letting operators branch capacity off a shared line system at multiple sites.

Please confirm shelf type and slot compatibility before ordering, as add-drop card families varied across equipment generations. Tech-Star is UK-based and ships worldwide. Get in touch to confirm compatibility with your Nokia system.
