The HFC Evolves Through the years, with the demand for additional speed and bandwidth cable systems have: Migrated from analog channels to 6 MHz SC QAM channels Migrated from modulation schemes from 16 QAM up to 256 QAM channels Migrated to DOCSIS 3.1 OFDM carriers consuming much larger areas of the spectrum Began migrating from […]
The Early Days of CLI Leakage The new regulations required the operator to monitor, measure with a specific technique, and log all system leakage. The operators soon realized that this was a difficult task with their current equipment, as signal level meters had insufficient sensitivity to measure 20 uV/m at even 10ft, much less be […]
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 […]
Cable network maintenance techs and contractors at times need to find and fix cable breaks or faults, which are likely to occur in network locations that impact many subscribers, with a degradation in service or even a complete outage. This means that quick, simple, accurate and high-resolution testing is required. Sometimes the cable is underground, […]

With so many KPIs and metrics for tracking security and performance over networks, clouds, clients, and applications, it’s difficult to see how SecOps and NetOps engineers ever rise above the noise. VIAVI Solutions takes a different approach to eliminate the noise and improve engineer effectiveness in solving issues. An example of this in Observer is […]
Optical interconnectivity at 400 Gbps has introduced many new design challenges. These include the step from NRZ to PAM-4 coding with the presence of a background error rate, the new QSFP-DD form factor for transponders with thermal and integration challenges and aggressive cost expectations early in the lifecycle. One of the most difficult challenges is […]

The impact of IoT, hybrid IT and decentralized networks is dominating conversations and column inches. Topics range from how to manage and investigate security and performance issues to the effect on user experience and interaction. In response, vendors and analysts have muddied the waters with phrases such as artificial intelligence and predictive analytics, rather than […]
Over the past several months, we have been taking a closer look at Multi-Fiber MPO connectors and how the continued growth of this technology is changing the dynamic for contractors. As data centers are rapidly scaling up their networks to support 40G and 100G speeds, multi-fiber MPO connectors are being used throughout the network architectures. […]
