Advanced Upstream Blog Series Introduction In the Advanced Upstream blog series we will explore how cable operators have traditionally managed upstream bandwidth capacity planning, how market dynamics and technical innovation are driving changes, and where things are likely headed in the coming years.  In this entry we will lay the groundwork for discussion of the […]

Tag – You’re It!  Signal Tags and Their Use in Cable Signal Leakage Detection Cable signal leakage technologies have been around for more than three decades, and while the underlying concept of detecting CATV signals leaking out of the network has not changed, the technologies to accomplish this have changed considerably.  Shortly after the first […]

Change Ahead – How Network Maintenance Practices Are Evolving With The Rapidly-Changing HFC The recent pace of change in HFC networks has been dizzying compared to our previous gradual evolutionary path, but fortunately plant maintenance practices including plant leakage detection have evolved to stay ahead of the curve.  The rapid expansion of FTTH offerings combined […]

Signal Leakage in Cable Networks, a Long and Winding Road Cable is a unique communications medium that has evolved from a rudimentary patchwork of transmission lines and components devised by an industrious group of technology pioneers decades ago into the leading broadband juggernaut that it is today.  The remnants of this journey are still evident […]
