Fiber everywhere

The new reality for a futureproof infrastructure for 5G, IoT and beyond

What does fiber everywhere mean?

Networks are experiencing an explosion of new services with unpredictable needs, including an insatiable growth in bandwidth driven by broadband services, massive scaling expected for IoT and 5G devices, and mobile edge computing driven by latency concerns from critical services.

These are just a few of the factors driving growth in fiber everywhere and challenging the carrier’s ability to handle this new reality. Supporting this highly scalable and flexible infrastructure requires a different set of skills and processes.

With 100 G/bits and soon 400 G/bits becoming the norm, fiber is the only solution. Having a fiber network that’s ready for this and the skills to deploy new fiber quickly—without issue when there isn’t enough—will be essential to maintaining a competitive advantage.

Fiber-to-the-edge and mobile-to-the-end-user are no longer a dream, but a reality. Are you ready to embrace fiber everywhere?

EXFO has the solutions and expertise you need to take fiber everywhere.

Solutions

The transformation to an all fiber network is an essential for today’s networks. Whether it’s converting the central office into a data center (CORD), replacing coax and analog fiber systems in the MSO access (fiber deep), evolving to a centralized RAN (C-RAN) architecture in preparation for 5G or upgrading existing fiber systems to 100G or 400G for more capacity, fiber will play a vital role. Having the right processes, skills and tools will ensure your transformation is successful. Are you ready?

Fronthaul testing

Transforming the RAN network into a centralized RAN (C-RAN) architecture is a critical aspect of the larger move to 5G, driven by the need to scale bandwidth to the radio head, reduce power and space requirements at the radio head and drive OPEX savings. By centrally locating the baseband units (BBUs) and feeding remote radio heads (RRHs) with fiber, MNOs can significantly improve operations efficiency. However, these savings are only half the battle. 5G will also bring a considerable increase in RRHs to deal with the anticipated bandwidth requirements of 5G applications. This will, in turn, increase RF interference issues, which can be very time consuming and expensive to isolate.

Having a fronthaul monitoring solution that covers both the fiber infrastructure and the CPRI signals in the fronthaul, to identify and isolate RF interferers, will be critical to operations efficiency. Being able to remotely identify RF issues, including which specific RRH is impacted, will save technicians significant time by eliminating unnecessary truck rolls.

EXFO has the fronthaul monitoring solutions you need to gain 100% visibility and optimize operations.

Test automation

As carriers continue to transform their networks to address everything from streaming broadband content to IoT to 5G and more, they are also required to deploy the necessary fiber infrastructure to support this demand. With construction projects regularly deploying thousands of fibers at a time, getting the job done in a timely manner and with 100% visibility into the quality of the installation is a concern. Knowing that every fiber has been tested and characterized properly and that issues are identified early and flagged appropriately for follow up is critical to both the carrier’s service goals and, in the case of installation contractors, getting paid quickly.

Having a test automation solution that can configure test setups, upload results, ensure 100% compliance with test methods, provide complete visibility to schedule progress and analyze the results to validate 100% of all fibers will be essential to any future construction project. Additionally, analytics from the test results can be used to inform training programs and identify poor contractor performance.

As the leader in fiber testing solutions, EXFO has the test automation solutions you need to take control of your fiber construction projects.

Fiber characterization

Every day, thousands of miles of new fiber are installed in networks throughout the world in anticipation of an explosive growth in bandwidth and to drive fiber closer to the end user. But what about the fiber already installed? Can this infrastructure support signaling rates beyond 10 Gbit/s?

Characterizing fiber in data centers, central offices and outside plants for 100 Gbit/s or eventually 400 Gbit/s is more complicated than for 10 Gbit/s, which was considered high speed when deployed. It takes more than a light source and power meter (LSPM) to guarantee that these higher-speed signals can be carried flawlessly. Given that an OTDR can significantly extend the amount of time needed to test, balancing OTDR usage with LSPMs will help you remain on schedule while minimizing risks.

EXFO has the experience, solutions and products—including our industry-leading intelligent Optical Link Mapper (iOLM)—you need to fully characterize any fiber upgrade project with complete confidence.

Fiber inspection

The leading cause of fiber-optic signal quality issues within the data center or outside plant is contaminated or damaged connector endfaces. In fact, a recent NTT Advanced Technology study reported that well over 80 percent of issues were due to contamination, followed by damaged ferrule endfaces. 100 percent inspection of all fiber connectors is necessary to fully characterize new builds and rehabilitation projects.

Today’s networks further complicate this issue by leveraging multifiber push-on (MPO) connectors which can pack 12, 24 or even 32 fibers into a single connector not much bigger than a standard single-fiber connector. With fiber spacing in the order of 250 nm, inspecting each fiber individually becomes a challenge, especially with legacy inspection solutions that use manual adjustments.

EXFO’s fully automated fiber inspection solution includes specialized nozzles for MPO and LC connectors, meaning the same tool can inspect either configuration. And with automatic, fully indexed scanning of every fiber in the connector, testing an MPO is quick and easy, leading to 100 percent coverage of all fiber connectors in projects of any size.
