Lowest loss of any terrestrial grade single-mode fiber

SMF-28® ULL Optical Fiber

SMF-28® ULL Optical Fiber

Corning® SMF-28® ULL fiber has the lowest loss of any terrestrial grade single-mode fiber with a maximum attenuation of 0.17 dB/km at 1550 nm. SMF-28 ULL fiber is the most widely used ultra-low loss terrestrial fiber with millions of kilometers sold and deployed worldwide in the harshest environments and most demanding long-haul applications, where 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.

Combined with advanced optical networking equipment, our latest ultra-low-loss optical fiber technology offers simplicity and reliability for operators. SMF-28 ULL fiber enables service providers to transmit information across longer distances and use less equipment, therefore reducing installation and maintenance costs. SMF-28 ULL fiber is suitable for operation in O, C, and L-bands.

SMF-28 ULL fiber can be purchased natural or colored. Corning fibers with 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.

SMF-28 ULL fiber is now available in a smaller 200 micron nominal coating diameter.
