Abstract

We demonstrate single-laser 32.5 Tbit/s 16QAM Nyquist wavelength division multiplexing transmission over a total length of 227 km of SMF-28 without optical dispersion compensation. A number of 325 optical carriers is derived from a single laser and encoded with dual-polarization 16QAM data using sinc-shaped Nyquist pulses. As we use no guard bands, the carriers have a spacing of 12.5 GHz equal to the symbol rate or Nyquist bandwidth of the data. We achieve a net spectral efficiency of 6.4 bit/s/Hz using a software-defined transmitter, which generates the electric drive signals for the electro-optic modulator in real time.

(Color online) Concept for a Nyquist WDM transmission system. In the transmitter, an optical comb source generates the optical carriers. Filters, namely an interleaver (IL) and an optical demultiplexer (DMX), separate the optical carriers. Nyquist transmitters (Nyquist TX1, 2, …, N) encode the data. Multiplexers (MUXs) and a standard optical coupler (C) combine the transmitter outputs. After transmission, a coupler (C) and optical demultiplexers split the carriers for the Nyquist receivers (Nyquist RX1, 2, …, N). The schematic spectra illustrate the Nyquist WDM transmitter and receiver concept for a total number of N = 6 optical carriers. Spectra of odd carriers (red), spectra of even carriers (blue), and MUX/DMX transfer functions (green) are shown.

(Color online) Implementation of a real-time transmitter for sinc-shaped Nyquist pulses. Two FPGAs are programmed to generate the PRBS ( 2 15 1 ), to perform symbol mapping, and to provide pulse shaping with an FIR filter. The in-phase (I) and quadrature (Q) signals are converted into the analog domain using two high-speed VEGA DACs. Image spectra are removed with additional anti-aliasing filters, and the resulting signals are amplified for driving the optical IQ modulator. Insets: Simulated eye diagrams for I and Q drive signals, sinc pulse and corresponding spectrum at the output of the transmitter. The simulated eye diagrams illustrate that there is only a small tolerance in clock phase when receiving such a signal, which makes a proper clock phase recovery procedure extremely important [23].

(Color online) Nyquist WDM setup. (a) A mode-locked laser (MLL) produces a frequency comb (see inset above (a)) which is broadened in a highly nonlinear fiber (HNLF). A waveshaper (WS) equalizes the resulting comb of 325 lines and replaces the unstable central part by a copy of the original MLL comb. An optical interleaver (IL) separates odd and even carriers (power spectra in the inset above (a)). On these carriers the transmitters Tx1 and Tx2 (see schematic in Fig. 2) encode 16QAM data in the form of sinc-shaped Nyquist pulses. Polarization multiplexing is emulated. The arrow points to the resulting optical power spectrum (inset below (a)). (b) The optical signal is then transmitted over one or up to three spans of Corning SMF-28 with EDFA-only amplification. (c) In a coherent Nyquist WDM receiver a WS selects a 60 GHz wide group of Nyquist channels fitting to the bandwidth of the optical modulation analyzer (OMA). An external cavity laser (ECL, Agilent 81682A) provides the local oscillator for the coherent receiver. (d) Two-sided RF power spectrum after down conversion from an optical carrier at 1563.6 nm (red) and from the adjacent carriers (black). The rectangular shape of the spectra proves the effectiveness of the Nyquist pulse shaping.

(Color online) Experimental results for the transmission experiment. The measured error vector magnitudes for all subcarriers (black squares—polarization 1, red dots—polarization 2) and the received optical spectra (blue line) are plotted for (a) back-to-back characterization, (b) transmission over 75.78 km, and (c) transmission over 227.34 km. For selected EVM values in the area around the highest EVM values (green triangles), the BER was measured and the results are displayed in Table I to verify the applicability of BER estimation from EVM measurements. Corresponding constellation diagrams for the carrier at 1550.015 nm are shown for the various transmission distances.

(Color online) Statistical analysis of selected carriers. We show constellation diagrams of the carriers used for checking the validity of the assumptions for the BER–EVM relationship presented in Eq. (1). We performed a statistical analysis of the in-phase (I, black) and quadrature-phase (Q, red) error vectors. The respective Gaussian fits (for I, green and Q, blue) indicate a Gaussian probability density function of the added noise as required for the reported BER estimations.
