Turn up new services right the first time, detect issues sooner, and fix them faster with field instruments and systems designed to work together to deliver the highest service quality and most efficient workflows.
Perform Flawless Service Installations First Time, Every Time
As network technologies continue to evolve, including DOCSIS 3.1 and beyond, fiber to the home including various PON options, and more technicians need to have the capability to verify performance and troubleshoot quickly and efficiently. Techs may encounter multiple access technologies in the same network on the same day, so being prepared with equipment that can perform the tests thoroughly and efficiently is essential. Access to the customer’s home is by appointment only, so getting the job done right is a high priority to avoid repeat service calls.
Service activation test gear from VIAVI empowers techs for whatever test challenges they may face in the cable access network. From DOCSIS 3.1 performance testing to fiber tests, to Ethernet and WiFi, VIAVI test equipment makes the job quick and easy for the technician. Tests for ingress and in-home leakage help to ensure not only optimal performance within the home but help prevent problems in the home from impacting neighboring customers. Test for WiFi coverage within the home help to prevent call-backs and enable customer education and satisfaction. Planning jobs and collecting test data in the cloud with StrataSync helps to automate the process and ensure that all needed tests have been performed.
HFC Plant Maintenance and Troubleshooting
Maintain your plant to maximize customer satisfaction while minimizing OPEX spend. It is an established fact that well-maintained plants provide better service quality and ultimately cost less to operate vs those that have been neglected. With the advent of OFDM and OFDMA, it is even possible to push considerably more traffic through the existing networks/spectrum via higher modulation orders if the plant is kept tight. This can result in deferral or even elimination of network capacity growth CAPEX. Overtime can be reduced and ingress remediation fire drills eliminated by detecting and fixing plant shielding weaknesses as they occur instead of waiting until they are impacting services.
VIAVI offers a broad plant maintenance portfolio including interoperable solutions covering both fiber and RF domains. Fiber tools range from centralized fiber monitoring solutions to alert on and localize fiber issues to handheld OTDR’s, power meters, and more. In the RF domain signal leakage detection systems can detect and pinpoint shielding weaknesses allowing ingress into your network, plus field meters and return path monitoring to round out the ingress tool box. Forward and return sweep capabilities ensure that both legacy and DAA nodes can be properly balanced, plus provide rapid troubleshooting capabilities when outages do occur. Interoperability between these tools enables workflows with maximum efficiency and effectiveness. By overlaying detected leaks, PNM data, historical field meter test results, and QoE data on a single map operators can easily prioritize maintenance issues based on subscriber impact and find/fix them quickly once in the field.
HFC Monitoring and Service Assurance
Maximize revenue, improve NPS performance, and introduce new services faster with confidence via superior service assurance capabilities. Whether you are a Technical Operators Manager focused on improving subscriber QoE or in the Service Assurance area focused on maximizing revenue from your network assets, VIAVI has monitoring and service assurance solutions to meet your business needs.
For technical operations teams, it is critical to detect network issues before they become service impacting and to prioritize which to address first based on current or potential customer impact. VIAVI achieves these goals by leveraging both dedicated HW-based probes and virtual sources to correlate service impacts with physical layer symptoms. PNM-based analysis combined with overlay of VIAVI leakage data, field meter data, and fiber monitoring system data provide unmatched insight to help operators resolve the issues that matter most.
For Service Assurance users, VIAVI offers systems to help them combine data from a wide variety of sources, apply powerful analytics, and use customizable dashboarding/reporting capabilities to uncover and track true needle-moving initiatives. Revenue can be maximized by identifying regions with greatest need for QoE improvement projects, mining CCAP/CPE deployment data to know where new services can be launched, and finding the best opportunities for upselling. VIAVI has a team of experts with significant domain experience ready to ensure that you achieve maximum value from your service assurance investment.
Simplify Network/Technology Transitions
HFC networks have evolved over time from simply connecting a few homes to a community antenna into a bi-directional network delivering broadband, video, phone, and more. Even in just the last 10 years there have been multiple frequency extensions, carrier count expansions, bonding of DOCSIS carriers, redistribution of network functionalities out into the network, and the introduction of a totally new modulation/error-correction scheme. With each of these changes cable operators were forced to evolve their facilities, service provision equipment, test gear, and work processes to enable the changes and maximize their benefits.
VIAVI has been a trusted partner with cable operators for decades and have provided knowledge and tools to make these transitions as simple as possible. VIAVI was first to market with fully DOCSIS 3.0 compliant 8x4 testing, DOCSIS 3.1 field meters for service testing, and continues to lead the way in advanced OFDM/OFDMA testing. Distributed Access Architectures (DAA) like Remote PHY were going to be extremely disruptive to plant maintenance and monitoring processes, but by working collaboratively with all leading NEM’s through the VIAVI DAA Test Ready program solutions were developed to enable the use of common tools and workflows for both legacy and DAA nodes. VIAVI also continues to lead in the fiber portion of the HFC as technologies like DWDM migrate into the access network.
Change is a given in HFC networks, and the pace does not appear to be slowing with capabilities like full-duplex DOCSIS (FDX) and extended spectrum DOCSIS (ESD) on the horizon for cable supporting the 10G initiative. You can trust that regardless of your future plans, VIAVI will be the partner of choice to help ease your technology transitions.
