OFS Announces Higher DWDM Capacity Over TeraWave ULL Optical Fiber with Nokia Commercial Ultra-Wideband C+L-Band System

LOS ANGELES, CA – OFS showcases the capacity and un-regenerated reach of Nokia's 1830 Photonic Service Switch (PSS) Ultra-wideband C+L- band DWDM system over OFS' TeraWaveTM ULL optical fiber, helping to reduce cost-per-bit of transport across the ultra-long haul distances needed to connect hyper-scale datacenters. TeraWave ULL optical fiber has the largest available effective area for a terrestrial fiber, allowing maximum suppression of non-linear penalties that limit the reach of high capacity, coherent modulation formats. The cost-per-bit of fully lighting a TeraWave ULL optical fiber can be up to 50% lower than the cost-per-bit of fully lighting a G.652 fiber by avoiding the high cost of regeneration to meet reach targets.

The Nokia 1830 PSS optical networking platform achieves ultra-long haul performance at 200G (using the 8QAM modulation format) and extended metro/DCI reach at high spectral efficiencies. The OFS TeraWave ULL ITU-T G.654.E optical fiber reduces amplifier noise by its ultra-low nominal loss of 0.168 dB/km and minimizes non-linear distortion by its large effective area of 125 microns squared. The waveguide of TeraWave ULL optical fiber was designed to minimize both micro- and macrobending losses in the L-band for good terrestrial cable performance and excellent splice performance.

For extended metro/DCI applications, TeraWave ULL optical fiber can support 400 Gb/s up to 300 km over 100 km spans without Raman amplification on the Nokia 1830 platform. With a hybrid Raman-EDFA amplifier, TeraWave ULL optical fiber can support 200 Gb/s transport up to 4500 km un-regenerated over 100 km spans. These link budgets assume realistic cable losses and margin for field deployment, using commercial gear.

OFS' TeraWave ULL optical fiber helps to cost effectively achieve the longest available un-regenerated reach for both traditional and cloud transport networks, where maximum capacity can be achieved by using advanced coherent modulation formats and C+L-band wavelengths.
