Xgig Approved for PCI-SIG

VIAVI is honored to have received approval from the PCI Special Interest Group (PCI-SIG). The PCI-SIG® is a consortium of more than 800 member companies that owns and manages PCI specifications as open industry standards.  This approval allows the VIAVI Xgig® Exerciser to be used for PCIe® Link and Transaction protocol compliance testing conducted by […]

Cable operators globally recognize that tight networks simply work better, and signal leakage is the best way to detect, find, and fix the shielding weaknesses which let undesirable upstream ingress into networks. Leakage monitoring has adapted with the evolving HFC to remain feasible and maximize effectiveness, but the migration to a 204MHz upstream with high-split networks […]

As high-bandwidth requirements continue to rise over the last few years, multiple system operators (MSOs) transform their hybrid fiber/coax (HFC) networks. Available architectures, such as DOCSIS 3.1 and Remote PHY, rely on fiber-based bandwidth deep into the cable television (CATV) network, which is why countless operators aim to create Node+0 architectures via “fiber deep” initiatives.  […]

There has been no doubt that fiber networks ensure the viability of smart-device applications, video streaming, and business requirements. However, with a demand increase, it only makes sense for service providers to continue striving for improvements in broadband access networks, which will require several tests on different network parameters, namely insertion loss, distance, and optical […]

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 […]
