Description
Summary:In this paper, we have experimentally demonstrated the C-band 4&#x00A0;&#x00D7;&#x00A0;25-Gb&#x002F;s non-return-to-zero <sc> on</sc>-<sc>off</sc>-keying (NRZ-OOK) signals over a 160-km single-mode fiber transmission based on 10G-class directly-modulated lasers and photodiodes. The excessive negative dispersion at the receiver side is used to equalize the frequency response of bandwidth-limited directly-modulated signal, therefore enables 25-Gb&#x002F;s NRZ-OOK transmission based on 10G-class optical devices. By employing a multichannel chromatic dispersion compensation module in the receiver, a single optical device can be used to equalize the frequency response of multiple channels realizing low-cost and high-capacity signal transmission. The results shown in this paper reveal that our proposed scheme would be a promising candidate for a low-cost transition to 100&#x00A0;Gb&#x002F;s (4&#x00A0;&#x00D7;&#x00A0;25&#x00A0;Gb&#x002F;s) for the point-to-point metro network applications.
