Fiber Type Matters When Simulating Optical Links and Latency

Simulating real-world fiber optic links and time delays in the lab environment is both a frequent and necessary task for engineers performing R&D and equipment certification testing processes.  With the evolution to more advanced network architecture, increasing speeds of 400G and beyond, and latency always being a key element, replicating the field network as closely as possible in the lab is critical to ensure systems will perform as expected post-deployment. 

Testing Plug-Terminated Links—Internationally

The Modular Plug Terminated Link, or MPTL, where a horizontal cable run terminated on one end to an RJ-45 plug connects directly into a device, has become increasingly popular for connecting a variety of devices—from wireless access points and security cameras, to PoE lights and video displays—essentially wherever it’s deemed impractical or unsafe to deploy an outlet and equipment cord. Approved within ANSI-TIA 568.2-D as an option for connecting devices, MPTLs aren’t just popular in North America. But some of you have asked about regions that don’t follow TIA standards, and if it possible to test an MPTL to ISO/IEC or CENELEC standards. While the short answer is “not yet,” you can still make sure your MPTLs will perform.

Inspect Before You Connect Poster

Do you Inspect Before You Connect? The VIAVI full-size wall poster will serve as a helpful reminder that Contamination is the #1 Reason to Troubleshoot Optical Networks. Dirty connectors cause 80% of field test failures. Microscopic debris significantly degrades signal performance and can cause permanent damage. Mating dirty connectors can break apart, spread, and migrate particles. And a typical dust particle is 2 to 15 µm and is only visible with a microscope.

Webinar: Performance Data ≠ User Experience

IT teams have more metrics than ever before. Yet according to Forrester Research, one-third of user complaints linger without resolution for a month or more. Do you have the right insight to understand and resolve user problems? In this webinar learn how the end-user focused technologies of Observer 17.5 simplify user experience assessment and troubleshooting to: Improve engineer’s ability to triage problem response and assign support tickets; Facilitate faster root-cause analysis with user-experience driven workflows; Ensure performance visibility in next generation 100 Gb data centers; Understand how users, by location or service, are experiencing an application.

Advice on overcoming common PoE challenges

As many different applications increasingly adopt Power over Ethernet (PoE) devices, such as phones, cameras, lighting, and access controls, IDEAL Networks is offering  advice to help IT technicians handle everyday PoE troubleshooting scenarios including: when a VoiP phone doesn’t work, a VoIP phone needs replacing with a higher power device, or an IP CCTV camera is stuck in boot cycle.

5G means new RAN architectures, densification and more fiber

Because of all the new requirements (e.g,. low latency, more bandwidth), new technologies (e.g. eCPRI) and new line rates (i.e. 10G, 25G) that 5G is imposing on the network, new testing practices must follow suit. Where bad splices or bad connections occurred in the past, 4G networks were quick to forgive, but 5G networks definitely won’t. So, unless thorough 5G testing practices are strictly followed, failure rates on new 5G deployments will increase.
