Viavi Solutions has launched new software and hardware modules for optical time domain reflectometry (OTDR) that allows remote monitoring and testing of passive optical network (PON), 5G and data centre networks.
A patented Flash Fibre Monitoring feature for ONMSi and SmartOTU software enables operators to detect and locate a flash attenuation that causes network route flapping and burst network error conditions.
This is 100 to 300 times faster than traditional monitoring, with performance that can detect flash attenuation in 0.1s. Network route flapping is one of the most common but damaging and difficult problems to diagnose. Until now, operators had no way to detect or locate flash attenuation events that are a root cause of millions of communication errors globally every year.
Micro and nano modules for the iOTDR integrate OTDR technology into network elements with reduced power consumption and footprint. The software library for the cards provides operators with a range of uses cases via an element-integrated iOTDR solution, potentially saving R&D teams two to three years of development time. The cards support fibre characterization, fibre monitoring, tapping security intrusion detection, fault demarcation, Raman amplified link test, and tracking fibre degradation for preventative maintenance.
Fibre network analytics using the NITRO BI Fibre Insight Platform for ONMSi automates fibre diagnostics to proactively eliminate risks and create a prioritized network performance improvement action plan. The fibre trends and aging use cases allow operators to see simplified reporting across the entire fibre network to revise procedures. All fibres can be graded by the cable, customer, network location down to the root cause fault type – turning mountains of raw data into actionable insight.
Optical network data rates are pushing new limits in transmission speeds due to wavelength and fibre density through dense wavelength division multiplexing (DWDM), high fibre count cables and complex point-to-multi-point and multi-fibre push on (MPO) architectures. Automated, remote intelligence allows for the ability to scale high quality standards and speeds without adding commensurate expense and workload.
“With these additions to the ONMS line, VIAVI innovation continues to lead the industry in helping customers scale construction and maintain performance of critical fibre infrastructure to alleviate years of workload on network staff,” said Kevin Oliver, Vice President and General Manager, Converged Instruments and Virtual Test, VIAVI. “With the ability to proactively monitor fibre using automated, remote test capabilities – service providers, NEMS and hyperscale operators can reduce expensive downtime and repair dispatch using proactive, assessment of the network health, improving the performance, reliability and customer satisfaction across the fibre lifecycle.”
Viavi has two types of optical test heads that work in tandem with ONMSi and NITRO software to enable operators to optimize flexible OTDR capabilities, rack footprint and price point. The system can be used for PON construction and service provisioning, ongoing monitoring, infrastructure monitoring and network security applications.
