Abstract
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.
