Celebrating the 20^ th anniversary of Optics Express, this paper reviews the evolution of
optical fiber communication systems, and through a look at the previous 20 years attempts to …

Randomly-coupled multi-core fiber (MCF) technology has come to attract lots of attention
because of its strong applicability to long-haul transmission systems. Compared with weakly …

The potential transmission capacity of a standard single-mode fiber peaks at around
100Tb/s owing to fiber nonlinearity and the bandwidth limitation of amplifiers. As the last …

Inter-core crosstalk is a potential limitation on the achievable data-rates in optical fiber
transmission systems using multi-core fibers. Crosstalk arises from unwanted coupling …

Coupling mechanisms and design issues in multi-core fibers (MCFs) for space division
multiplexing are described in this paper. For uncoupled MCFs, a design procedure that …

We compare the networking merit of two possible multiplexing techniques on top of
wavelength division multiplexing to enlarge transmission capacity: the band division …

We demonstrate a record-long 10-mode-multiplexed transmission over 1300 km using a 6-
LP few-mode fiber (FMF). Long-haul mode-division-multiplexed (MDM) transmission …

Since its early commercial deployment in the late 1980s, optical fiber has evolved to become
the predominant carrier of the globe's communications. Yet, after accommodating the world's …

Since optical submarine cable systems are a part of the global communications
infrastructure, their total capacity must be continuously and dramatically enlarged. Recently …

We have achieved the longest three mode-multiplexed full C-band transmission yet attained
over 3060 km. In wideband mode-multiplexed transmission over weakly-coupled fewmode …
