“…To provide a cost-effective transition to a 40 Gb/s line rate, it is essential for 40 Gb/s channels to be accommodated within the existing 10 Gb/s dense wavelength division multiplexing (DWDM) networks infrastructure, which consists of conventional erbium-doped fiber amplifiers and standard single-mode fiber [7]- [9]. To date, studies on 40 Gb/s over 10 Gb/s infrastructure have focused on nonlinear behavior [7], dispersion effects [8], and the add-drop issue [9]. However, smooth transition from 10 Gb/s to 40 Gb/s is important, and 40 Gb/s channels should be introduced on a line card basis in active 10 Gb/s-based DWDM links, gradually replacing 10 Gb/s channels as the traffic grows.…”

In this paper, we propose and demonstrate a cost‐effective technique to upgrade the capacity of dense wavelength division multiplexing (DWDM) networks to a 40 Gb/s line rate using the existing 10 Gb/s‐based infrastructure. To accommodate 40 Gb/s over the link optimized for 10 Gb/s, we propose applying a combination of super‐FEC, carrier‐suppressed return‐to‐zero, and pre‐emphasis to the 40 Gb/s transponder. The transmission of 40 Gb/s DWDM channels over existing 10 Gb/s line‐rate long‐haul DWDM links, including 40×40 Gb/s transmission over KT's standard single‐mode fiber optimized for 10 Gb/s achieves successful results. The proposed upgrading technique allows the Q‐value margin for a 40 Gb/s line rate to be compatible with that of 10 Gb/s.

“…The signal then drives a Mach-Zehnder modulator at an amplitude of 2Vpi, generating a three-level signal for the electrical field (two levels for the intensity) with narrower optical bandwidth compared to conventional NRZ coding [1,[3][4][5].…”
