Abstract

We discuss the performance of a multichannel $2\times 10\mathrm{Gbit}∕\mathrm{s}$ polarization-multiplexed differential phase-shift keying transmission system. Through simulations and transmission experiments we find that, despite the constant power envelope of non-return-to-zero phase-shift keying modulation formats, polarization multiplexing strongly reduces the nonlinear tolerance and transmission performance at a $2\times 10\mathrm{Gbit}∕\mathrm{s}$ line rate with multichannel transmission. This results in a 10 dB power penalty when comparing single- and nine-channel transmission. Additionally, multichannel impairments in differential phase-shift keying and on–off keying are compared for $2\times 10\mathrm{Gbit}∕\mathrm{s}$ polarization-multiplexed transmission.
