The superabsorbent polymer (SAP) with different volumes and modes of entrained water is incorporated into concrete to study the effect of SAP on the compressive strength, flexural strength, shrinkage, plastic cracking and electrical resistivity of concrete at early age. The result indicated that the influence of SAP with different modes of entrained water on the early strength of concrete is relatively...
We experimentally demonstrate all-optical wavelength conversion of OFDM signals by using two-mode injection-locking in a Fabry-Pérot laser. We show the tradeoff between the capacity and performance, and measure the power penalty after wavelength conversion.
We experimentally demonstrate a 36-Gb/s DMT signal transmission over 50-km SSMF based on a cost-effective 10-GHz DML-based IM/DD system. The data rate is improved by 22% with Volterra filtering.
The capacity of single-mode fiber links with direct-modulation/direct-detection is limited by the fiber dispersion and laser chirp. which lead to frequency selective fading at the receiver. In such transmission channels, the capacity can be improved by adaptively modulated optical OFDM. In this paper, we discuss the capacity limits of such links using adaptively modulated optical OFDM both in theory...
