We report the results of 100G unrepeatered transmission aimed at achieving the longest distance without any inline active elements. The unrepeatered transmission system uses commercial distributed Raman pump modules, enhanced ROPA, and real-time proc

We extend the techniques used in unrepeatered systems to the case of two long spans without regeneration at the intermediate site. We report 15 Tb/s transmission over a cascade of two spans of 333.4 km and 298.6 km.

This paper reports ultra-long 100G unrepeatered transmission on NZDSF. $4\times 120$ Gb/s transmission over 402.7 km (82.8 dB) of NZDSF is achieved using a commercial Raman-based system and enhanced ROPAs with a dedicated pumping fiber.

We demonstrate that pump-to-signal cross-polarization scattering represents an impairment that limits the amount of forward Raman pumping used in polarization-multiplexed coherent systems. We also develop and validate experimentally an analytical noi

The worldwide subsea transmission infrastructure consists of a combination of long-distance repeatered and shorter distance unrepeatered cable systems. This chapter addresses unrepeatered systems, also known as repeaterless or single-span systems. On
