Optical Cabling in the Data Center: Preventing problems through testing

The seamless interconnect of data center facilities is needed to deliver lightning-fast speeds, and yet internet content providers (ICPs) have grown at such a rate there has barely been enough time to create the rigorous testing regiment necessary. Add the rising cost of cabling infrastructure and the array of interoperability protocols to the mix, and the scale of the challenge becomes even more overwhelming.

How to Select the Best Network Monitoring Technology

Experts agree that monitoring is essential for maintaining overall network performance, health, and security. But exactly which features should a network monitoring tool offer, and how should the technology be used to achieve maximum effectiveness? As both networks and network management goals advance and evolve, these questions are becoming increasingly difficult to answer, making it challenging to locate and deploy a monitoring technology that covers all of the essential bases.

Webinar: Best Practices in Enterprise Fiber Connectivity

Fiber connectivity is essential for the physical infrastructure in any enterprise or data center network. While it certainly has advantages, there are also challenges that come along with fiber. Contamination is the #1 cause of troubleshooting in fiber networks, so it is critical that anyone working with fiber is aware of and implementing best practices when handling, installing, or testing fiber connections. During this one-hour session, we will take a closer look at fiber connectivity and educate attendees on the impact that contamination has on fiber connections and network performance. We will also provide guidance on best practices and standards that are in place to ensure clean connections.

Threat Hunting. The Best Security Intelligence & Threat Hunting Tools

Threat hunting is a focused and iterative approach used to proactively detect and eliminate threats that may have evaded traditional security tools. These threats include attacks or malware that infiltrate a business or organization’s network, leading to stolen intellectual property or personal information of customers and employees. As the complexity of network architecture has increased, the sophistication of “bad actors” perpetrating cyber-crimes has followed suit, making threat hunting an important and fast-growing element of the cyber security landscape.

From 400G Field Testers to 800G Lab Validation: VIAVI To Unveil Advanced Solutions at ECOC 2019

VIAVI is introducing new solutions at ECOC including: The T-BERD/MTS 400G Network Tester, which provides rate integration spanning from 400GE down to T1/E1 in addition to fiber optic testing using OTDRs and WD  Channel Checkers along with interfaces such as QSFP-DD and SFP-DD. The MAP-300 photonic metrology and test automation platform delivers the precision required for laboratory testing, combined with configurability to meet the demands of the manufacturing process. Remote automation functionality, along with multi-user architecture, helps increase capital utilization and dramatically reduce the cost of testing.The modular OTU-8000 Optical Test Unit with a tunable DWDM OTDR and the ultra-compact OTU-5000 rack-mounted OTDR  supports rapid, automatic identification of fiber events such as bends, crushes, breaks and malicious tapping. A single optical test head can test hundreds of fiber links, and auto reports the GPS location of a fault within minutes, dramatically reducing the time and cost of construction and repair.

4 out of 5 IT teams are involved in security efforts

VIAVI’s 12th annual State of the Network global study of enterprise networking challenges shows that more than 4 in 5 IT teams are involved in security efforts, and a majority of them report an increase of at least 25 percent in time spent on these efforts over the past 12 months. But according to Viavi, the study’s “most striking conclusion is that network-based conversation wire data has become the top data source for security incidents, with its use tripling, demonstrating that threat levels have driven enterprises to seek the most reliable forensic data available.

State of the Network

For over 12 years VIAVI Solutions has conducted the global State of the Network Study. This year over 600 IT professionals weigh in on the workloads, challenges, data sources and team collaboration required to safeguard critical corporate assets. The State of the Network Study from VIAVI Solutions examines critical trends and technologies that shape network management. The annual study assesses the adoption and IT management challenges of emerging technologies, tracks key application and network issues, and projects organization bandwidth demand.  


To support a successful transition, 5G test practices are being developed and refined to ensure the consistent performance that end users demand. The collective tools, software, protocols, and practices required for all 5G deployment phases form the core of the emerging 5G testing field. Achieve optimized deployment with the VIAVI Test Guide to 5G Network Deployment.

Tomorrow’s 5G Killer Apps And The Network That Will Empower Them

What kinds of use cases will ultimately become killer apps on the 5G network? Without question, 5G will improve existing services and support expanded capabilities for the future. With reliable always-on connectivity, low latency, and substantial increases in bandwidth, tomorrow’s 5G networks will fundamentally transform the way that businesses and consumers interact with technology. Arguably the most important feature of 5G will be seamless connectivity across multiple device types and settings. The internet of things (IoT), along with other technologies at the edge of the network, will leverage this capability to enhance traditional markets and create entirely new ones. In fact, in a 2018 Gartner survey, 66% of companies surveyed plan to deploy 5G-based IoT applications by 2020.

VIAVI Demonstrates Industry-First PCI Express 5.0 Test Platform at PCI-SIG

Viavi Solutions gave the first demonstration of protocol analysis for the recently completed PCI Express® 5th generation data communication standard at the PCI-SIG Developers Conference, June 18-19. PCIe 5.0 – the next revision of the ubiquitous serial computer expansion bus standard – will double the capacity over a PCI Express link to 32 gigabits per second per unidirectional channel or greater than one terabit per second across the common 16-lane bidirectional slot interface. This acceleration of speed correlates with the performance demands of emerging bandwidth- and compute-intensive applications such as 400-Gigabit Ethernet, IoT, hyperscale and AI.
