To support the exponential growth of global data traffic, 100 Gb/s submarine transmission systems are being installed in transoceanic links. These systems offer capacity up to ~10 Tb/s on a single core fiber using a C-band Erbium doped fiber amplifier (EDFA).

However, there are distinct challenges involved in developing and deploying high-capacity transoceanic distance transmissions systems. One issue is the need to improve optical signal-to-noise ratio (OSNR) within the entire C- and L-bands.  Another limitation lies in delivering electrical power to the offshore equipment supplying EDFA pumps.  In addition, long haul undersea submarine systems are typically much longer than terrestrial systems and have unique requirements for fiber optic cables and repeaters used in harsh subsea environments.

In a new white paper presented at SubOptic 2016, OFS and OFS Labs researchers discuss key fiber and amplifier technologies that help users to achieve high capacity and long reach for submarine transmission systems. These technologies include ultra-large-effective area, low loss optical fibers and their impact on performance, along with key amplification techniques for both repeatered and repeaterless submarine systems.
