The first all-in-one medium and long-range bidirectional testing and certification solution for hollow core fiber (HCF) was unveiled by VIAVI Solutions. The offering implements optical dispersion measurement (ODM) modules, VIAVI’s advanced 8100 Series OTDR modules, and ReportPRO software, which has particular algorithms that can carry out the bidirectional OTDR analysis needed for hollow core fibers.
Validation trials conducted in collaboration with fiber manufacturers, specialized contractors, and three leading hyperscalers have demonstrated the efficacy of the solution.
Hollow core fiber enables up to 30% lower latency, up to 70% reduced chromatic dispersion (CD), up to 65% lower attenuation, as well as reduced signal distortion as compared to single mode fiber. This allows for minimal data errors and losses and faster data transmission over increased distances without the need for amplification.
For data center interconnect between hyperscale campuses for AI, high-frequency financial trading, quantum communication, defense, and other applications where its use can significantly improve operational and service performance, hollow core fiber technology is becoming more and more popular.
Due to different optical properties including backscattering and spectrum range, as well as increased manufacturing and specialist contractor deployment costs, hollow core fiber projects necessitate greater investments and a wide range of tests.
To safeguard investments and guarantee future performance, especially over medium- and long-haul links, dispersion testing and attenuation profile (AP) are required in addition to bidirectional OTDR tests at higher wavelengths.
There aren’t many options for testing and certification, and those that employ OTDR-based dispersion test methods or lack the required OTDR performance might only be able to test shorter distances.
For hollow core fiber links, VIAVI’s solution is the only all-in-one certification solution that can perform bidirectional OTDR, PMD, CD, and AP testing and reporting.
It is suitable for all kinds of hollow core fiber, including DNANF and PBG, over short-, medium-, and long-distance links because of its industry-leading OTDR dynamic range performance and non-OTDR based dispersion testing. VIAVI’s OneAdvisor 800 Fiber platform serves as the host for these solutions.
Leadership Comments
“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.”
