OFS Develops Multicore Fibers (MCF) for its Submarine Fiber Portfolio

OFC 2023, Booth 3229, San Diego, California, March 6, 2023  OFS, a leading designer, manufacturer, and supplier of innovative fiber optic network products, announces the development of multicore fiber for its ocean product portfolio. TeraWave® SCUBA 4X Multicore Ocean Fiber is designed to optimally deliver four times the bandwidth in ocean applications using a four-core space division multiplexing (SDM) technology.

As submarine communication networks evolve to support net data rates of 1 Petabit/sec and higher, it is clear that revolutionary, not evolutionary, change is required in the wet plant hardware.  SCUBA 4X multicore fiber will form the foundation of a new generation of transmission technologies, designed to break through the bandwidth limitations of single-core optical fibers. With excellent transmission properties in C- and L-bands, SCUBA 4X has a demonstrated attenuation below 0.165 dB/km at 1550 nm and industry-leading adjacent core crosstalk of – 70 dB/km at 1550 nm.  Other properties will be consistent with G.654.B/C compliant submarine fibers (9.7 mm mode field at 1550 nm, cutoff wavelength below 1520 nm, and standard cladding and coating dimensions).

 “OFS and FEC are committed to be industry leaders in SDM-based communication technology, with a comprehensive product portfolio encompassing fiber, connectivity and fusion splicing,” said David DiGiovanni, Chief Technology Officer of OFS and President of OFS Labs.  “We are working with several key customers as they adopt this ground-breaking increase in bandwidth density.”

Two related presentations will be given at the OFC conference:  Polarity and Twist Rate Detection for Accurate and Reliable Low Loss Multicore Fiber Fusion Splicing (Tu2C.1) delivered by Tristan Kremp of OFS Laboratories, and Low Fusion Splice Loss Technique for Multicore Fiber with 2- and 3-Electrode Fusion Splicers (Th2A.10) delivered by Toshiyuki Fujii of Furukawa Electric Co., Ltd.

More information on SCUBA 4X multicore fiber, complementary Fitel fan-in/ fan-out devices, and live demonstrations of the Fitel S185 PM ROF multicore fusion splicer can be found at OFS booth 3229, March 7 – 9th at OFC and https://www.ofsoptics.com/multicore-optical-fiber/.
