SMF-28® ULL Optical Fiber

Lowest loss of any terrestrial-grade, single-mode fiber

Corning® SMF-28® ULL Optical Fiber Portfolio

Corning® SMF-28® ULL Optical Fiber Portfolio

Corning’s SMF-28® ULL optical fiber portfolio has the lowest-loss terrestrial-grade fibers available in the market – with millions of kilometers sold and deployed worldwide in the harshest environments and most demanding long-haul applications. There, ultra-low attenuation can be leveraged to extend network span lengths, skip amplification sites, upgrade to faster bit rates, add network components for improved flexibility, and/or lengthen the distance between regenerators. Ultra-low-loss optical fiber allows carriers and cloud operators to extend optical reach at very high data rates and makes networks scalable for higher capacities as the demand for bandwidth continues to grow.

The newest addition, SMF-28 ULL fiber with advanced bend, is an ITU-T G.654.C-compliant fiber with best-in-class performance specifications. This evolutionary product provides ultra-low loss, with attenuation available down to 0.15 dB/km at 1550 nm, lower latency, and meets the fiber macrobend loss requirements of the ITU-T G.657.A1 standard. SMF-28 ULL fiber with advanced bend is designed for the most challenging long-haul and high data rate networks, enabling customers to scale to ≥ 800G data rates at a lower overall cost per bit.

All products in the SMF-28 ULL fiber portfolio are also available in a smaller 200 μm outer diameter for use in high density cable designs.

SMF-28 ULL fiber can be purchased natural or colored. Fibers with Corning® ColorPro® identification technology, our coloring solution, enable cable manufacturers to reduce cost, minimize footprint, and leverage an enhanced product offering. Find more information about Corning ColorPro Identification Technology.
