hollow core fiber technical

"all-in-one medium and long-range bidirectional testing and certification solution for hollow core fiber (HCF)."

Hollow core fiber is a type of light-guiding cable where the center is mostly air rather than solid glass, so light travels through a hollow tube much like a bullet through a barrel. It can carry signals faster, with less signal loss and lower heating than conventional solid-core fiber, which matters to investors because it can reduce operating costs, enable lower-latency and higher-capacity networks, and open new markets in telecom, data centers, and sensing.

otdr technical

"algorithms for OTDR, dispersion testing and attenuation profiling"

An OTDR (Optical Time-Domain Reflectometer) is a handheld or rack-mounted instrument that tests fiber-optic cables by sending light pulses down the cable and measuring reflections to map length, signal loss, and faults—think of it as an ultrasound or sonar for fiber networks. For investors, OTDR use signals the health and maintainability of telecommunications infrastructure, affecting capital spending, service reliability, repair costs and the pace of network expansion.

chromatic dispersion technical

"up to 70% reduced Chromatic Dispersion (CD), up to 65% lower attenuation"

Chromatic dispersion is the tendency of different colors (wavelengths) of light to travel at slightly different speeds through an optical fiber, which causes pulses to spread out and blur over distance—similar to runners starting together but finishing at different times. For investors, it matters because dispersion limits how fast and how far fiber networks can reliably transmit data, influencing equipment specs, maintenance or upgrade costs, service quality and a company’s competitiveness in telecom and data-center markets.

attenuation technical

"up to 70% reduced Chromatic Dispersion (CD), up to 65% lower attenuation"

Attenuation is the reduction or weakening of something’s strength or effect over time or distance, such as a drug’s potency, a virus’s ability to cause disease, a signal’s clarity, or the impact of a business trend. For investors, attenuation matters because a smaller or waning effect can change a company’s future revenue, regulatory risk, or the value of an asset—think of it like turning down a volume knob: lower strength usually means less financial impact or lower urgency for action.

• Proven platform implements proprietary HCF-specific algorithms for OTDR, dispersion testing and attenuation profiling
• Solution has been validated in trials with three leading hyperscalers

CHANDLER, Ariz., Jan. 6, 2026 /PRNewswire/ -- VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) has announced the industry's first all-in-one medium and long-range bidirectional testing and certification solution for hollow core fiber (HCF). The offering implements VIAVI's advanced 8100 Series OTDR modules, optical dispersion measurement (ODM) modules and ReportPRO software, which includes specific algorithms capable of performing the bidirectional OTDR analysis required for hollow core fibers.

The efficacy of the solution has been tested and proven through validation trials in partnership with fiber manufacturers, specialist contractors and three leading hyperscalers.

Compared to single mode fiber, hollow core fiber enables up to 30% lower latency, up to 70% reduced Chromatic Dispersion (CD), up to 65% lower attenuation and reduced signal distortion. This enables faster data transmission over increased distances without the need for amplification and minimal data errors/losses.

Hollow core fiber technology is being increasingly adopted for data center interconnect between hyperscale campuses for AI, high-frequency financial trading, quantum communication, defense and other applications where substantial operational and service performance improvements can be achieved by its use.

Hollow core fiber projects require larger investments and an expansive range of tests due to increased manufacturing and specialist contractor deployment costs and differing optical properties such as backscattering and spectral range. In addition to bidirectional OTDR measurements at higher wavelengths, dispersion testing and attenuation profile (AP) are needed to confirm correct installation to protect investments and ensure future performance, particularly over medium- and long-haul links. Few testing and certification options exist, and those without the necessary OTDR performance or those that use OTDR-based dispersion test techniques may only being capable of testing shorter distances.

VIAVI's solution is the first all-in-one certification solution capable of bidirectional OTDR, PMD, CD and AP testing and reporting for hollow core fiber links. Thanks to industry-leading OTDR dynamic range performance and non-OTDR based dispersion testing, it is suitable for all types of hollow core fiber including DNANF and PBG over short-, medium- and long-distance links. These solutions are hosted on VIAVI's OneAdvisor 800 Fiber platform.

"A key advantage of hollow core fiber is that it transmits data faster over longer distances. However, testing for splice quality, connector losses and fiber integrity requires a different approach with higher-performance test solutions," said Kevin Oliver, Vice President and General Manager, Fiber and Access Solutions, VIAVI. "VIAVI's all-in-one offering has delivered strong results over short-, mid- and long-distance links in trials we've held in collaboration with leading fiber manufacturers and hyperscalers, allowing them to protect these larger investments in HCF and ensure future ROI."
