The pressure is on
AI is fueling the evolution of transport networks—but this acceleration brings new challenges, putting service providers under growing pressure to deliver flawless performance, control costs, and drive greater operational efficiency across evolving fiber and Ethernet infrastructures.
AI driving stricter SLAs
Stricter SLAs are necessary to meet QoS standards and end-user expectations on upgraded high-speed networks (100G, 400G, 800G). With more users and devices relying on the network, downtime is simply not an option.
Ethernet networks evolving faster than ever
Rising speeds and advanced optics add complexity—making “plug-and-pray” approaches unreliable and testing crucial to ensure performance across all rates.
Juggling emerging transceivers
Coherent optics enable faster speeds and longer reach in metro, core, and DCI networks—but require thorough testing to ensure interoperability, minimize disruptions, and maintain network reliability.
Keeping CAPEX and OPEX in check
New technologies may outpace technicians’ skills, complicating testing of high-speed links and causing delays, while costly investments in new tools may be required to meet emerging testing needs.
Lack of real-time job compliance visibility
Lack of real-time job compliance visibility can lead to repeat site visits and truck rolls, driving up costs and delaying revenue due to quality issues.
Overcoming fiber diagnostic hurdles
Limited visibility makes fiber fault isolation challenging, increasing MTTR and network downtime. Eliminating costly manual fault-finding streamlines operations and maintenance while ensuring network reliability.
Migrating to higher speeds is complex. Testing shouldn’t be.
Qualify the state of the fiber, turn up and activate links, and assess data transmission integrity with EXFO’s comprehensive test portfolio. Our solutions validate the high-speed transport network end-to-end—from the physical to the protocol layer—with first-time-right results, every time.
Fiber characterization
In next-generation fiber-dense networks, maintaining fiber quality is essential to ensure reliable performance, especially as service providers scale to 400G and beyond. Contaminated or faulty connections can lead to signal degradation, latency, and service disruptions. Proactive practices like fiber inspection, proper connector cleaning, and link qualification help prevent these issues, while enabling quick identification and resolution of problems such as bad connections, fiber bends, or breaks across long-haul, metro, and data center interconnect networks.
Link stability and validation testing
Confirming the integrity of high-speed links involves a variety of different tests (e.g., jitter and latency) to ensure interoperability and compatibility between various network components and confirm that services can stand up to strict SLAs. Tools need to be flexible and scalable to test lower rates as well as handle new and upcoming rates and technologies. Fiber testing is the basis of any infrastructure, but within transport networks there is a lot of ‘plug and pray’, resulting in problems down the road.
Transceiver validation testing
According to industry surveys, transceiver failure rates vary from 10% to 20%. Faulty transceivers will delay link deployment and service activation. As transceivers become more complex and expensive, such as digital coherent optics (DCO) and are often the root cause of costly deployment delays and network failures, replace and go strategies are no longer viable.
Service activation testing
Transport networks must support different types of traffic with varying QoS requirements, such as voice, video, and data. Validating the network’s capacity under various load conditions is crucial to ensuring it can handle current and future requirements. Plus, it’s vital to check QoS mechanisms that ensure traffic is prioritized appropriately to meet performance expectations.
Identifying fiber degradations in live networks
Continuous, automated and centralized monitoring of the fiber optic network ensures quick detection of abnormalities or disruptions. When problems arise, they can be quickly identified and solved, reducing mean-time-to-repair, minimizing network downtime and preventing service disruptions. This approach significantly improves the overall reliability and resilience of the fiber infrastructure.
