This study presents an evaluation of the time and modulation frequency-varying power
transfer of crosstalk in a homogeneous multi-core fiber (MCF). Experimental observations …

We report a two-span, 67-km space-division-multiplexed (SDM) wavelength-division-
multiplexed (WDM) system incorporating the first reconfigurable optical add–drop …

Researchers are within a factor of 2 or so from realizing the maximum practical transmission
capacity of conventional single-mode fibre transmission technology. It is therefore timely to …

Digital signal processing (DSP) combined with coherent detection has played a central role
in the recent capacity expansion of optical networks. Optical superchannels aim to increase …

We discuss optical transmission using homogeneous, single-mode, multicore fibers. We first
describe the key fiber properties that can affect transmission, such as intercore crosstalk and …

The advancement of digital coherent technologies has dramatically increased the system
capacity per single-core single-mode fiber to the point that we can now approach the …

We investigate high-throughput, multi-band transmission in a 4-core multi-core fiber (MCF)
with the same 125 μm cladding diameter of standard single-mode fiber (SMF). A single …

We demonstrate high speed optical transmission systems using digital coherent detection at
all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we …

An analytical discrete changes model of the inter-core crosstalk (ICXT) in real homogeneous
weakly-coupled multi-core fibers (MCF)(cores with similar but different parameters) with …

A two-span SDM system includes the first ROADM supporting spatial superchannels and the
first cladding-pumped multicore-EDFA directly spliced to multicore transmission fiber. For 6× …
