我们提出并演示了一种简单而灵活的方法来产生残留边带修改的双二进制归零（VSB MD-RZ）信号在10- 40 Gb/s，使用双驱动马赫-曾德尔调制器和失谐光学带通滤波器。通过与双边带MD-RZ（DSB MD-RZ）和常规VSB MD-RZ信号的比较，研究了该信号的性能。在10 Gb/s的误码率（BER）的测量表明，所产生的信号的错误的操作。在40 Gb/s的单模光纤传输100 km后，进一步观察到良好的性能。
We propose and demonstrate a simple and flexible approach to generate vestigial side band modified duobinary return-to-zero (VSB MD-RZ) signals at 10–40Gb/s, using a dual-drive Mach–Zehnder modulator and a detuned optical band-pass filter. The performance of the proposed VSB MD-RZ signal is investigated by comparing with double side band MD-RZ (DSB MD-RZ) and conventional VSB MD-RZ. Bit error ratio (BER) measurement at 10Gb/s shows an error free operation for the generated signal. Good performance is further observed after 100km of single-mode-fiber transmission at 40Gb/s.
