The Full Duplex (FDX) DOCSIS specification defines simultaneous upstream and downstream communications for symmetrical upstream and downstream data rate capacity. The specification leverages distributed access architecture (DAA) to enhance upstream capacity. The NCTI® Full Duplex DOCSIS course teaches the broadband technician about interferences that are unique to FDX operation and how these interferences are addressed. The course also explains the difference between full duplex operation and frequency division duplexing, and how both are used for FDX DOCSIS operations. Completing the NCTI FDX DOCSIS course prepares the broadband technician for FDX DOCSIS operations in their network.
Completion Time:
The estimated completion time for this course is four hours. The maximum allotted time is four months from enrollment.
Benefits:
- prepare for implementation of Full Duplex DOCSIS

Upon completing this course, students will be able to:
- list reasons for Full Duplex DOCSIS deployment
- define what full duplex operation is
- identify issues that are unique to full duplex operations
- identify the frequency band allocated for full duplex DOCSIS operations
- describe what is required of a fiber node for full duplex operation
- describe DOCSIS FDX-Limited modems
- describe how interference groups are used to limit interference between full duplex modems
- describe the sounding process and hierarchy of resource block assignments, transmission groups to manage traffic in full duplex interference groups
- describe echo cancellation at the node
- describe how adjacent leakage interference and adjacent channel interference at the modem is suppressed with echo cancellation
