Corning Introduces Ultra-Low-Loss Submarine Optical Fiber

Corning introduced an ultra-low-loss, large-effective-area fiber that is optimized for the next-generation, high-data-rate submarine networks.


Corning's "Vascade" EX2000 optical fiber has a typical effective area of 112 square microns (µm2) and average attenuation of 0.162 decibel of loss per kilometer (dB/km) at 1550 nanometers (nm). This enables extended system reach with fewer amplifiers in repeatered submarine networks. In unrepeatered submarine networks, Vascade EX2000 fiber can accommodate higher optical launch power and increased system span length.


Corning said it plans to use this new optical fiber to develop its next-generation dispersion-managed fiber solution, Vascade R2000 fiber, which enables 40 Gbps and 100 Gbps systems to reach transoceanic distances.


"Today, we face the first deployment of 40 Gb/s systems in submarine networks, and we expect that Vascade R2000 fiber and Vascade EX2000 fiber will play a critical role," said Barry Linchuck, director, worldwide marketing, Corning Optical Fiber.

Vascade EX2000 optical fiber is fully qualified and is being sampled and tested by submarine-system vendors around the world.
