The NCI-321/D is a 1.2-GHz double two-way narrowcast inserter for the next generation of CCAP equipment.

The NCI-321/D module has only two narrowcast inputs per section, but has two sections, meaning two outputs. With a fully populated NCI rack that comes with 23 slots (one of which is dedicated to the system controller), MSOs can actively feed 44 optical transmitters. Small, compact, low power, flexible and > 70 dB isolation features ensure the deployability of the NCI-321D for the next decade, the company says.
