OFS intros 4X Multicore Fibers (MCF) for SDM subsea cables

OFS introduced its TeraWave SCUBA 4X Multicore Ocean Fiber, promising four times the bandwidth in ocean applications using a four-core space division multiplexing (SDM) technology.

OFS said its SCUBA 4X multicore fiber will form the foundation of a new generation of transmission applications based on SDM.

The new fiber offers excellent transmission properties in C- and L-bands, with 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."
