Possibilities and Limitations of the ESD Return Path

The pandemic, consumer trends toward 4K television, and significant competition from fiber network companies is driving the cable access television (CATV) industry to rapidly increase upstream capacity. The latest version of the Data Over Cable Service Interface Specification (DOCSIS), DOCSIS 4.0, includes support for a significant increase in upstream capabilities, offering operators new possibilities. Extended Spectrum DOCSIS (ESD) technology, which enables use of higher upstream and downstream frequencies, introduces new challenges, which Teleste Intercept solutions are built to overcome.
