Upgrade of hybrid fibre coax networks towards bi-directional access

Research output: Chapter in Book/Report/Conference proceedingChapterAcademicpeer-review


In this paper we describe an upgrade scenario for Hybrid Fibre Coax (HFC) CATV Networks towards hi-directional access. The communication system described has been newly designed, and is based on the use of Direct Sequence- Code Division Multiple-Access (DS-CDMA). Due to its spread-spectrum properties, this technique enables the reliable and secure transmission of data in the hostile upstream channel. The future role of Graded Index Polymer Optical Fibre (GIPOF) for the replacement of copper sections of the network is discussed and a demultiplexer for a GIPOF WDM system is presented.
