Polarization beam splitters and 3dB couplers are used to construct a home-made90 ° optical hybrid, by  which polarization diversity optical coherent receiver is carried out with single-ended detection.A10Gb / s oscillation multiplexed differential phase shift keying (DPSK) signal is transmitted through280km Standard single- mode fiber (SSMF) using erbium-doped fiber amplifier (EDFA) amplification, and no error bits are measured in th result.

nrf2041,通讯的基本程序，是NRF公司提供的程序框架，是nrf编成的最终参考文档，在看懂了我上载的前几个文档以后，如果还有问题，那么只有这个文档能帮你了。-nrf2041, communication of the basic procedures that the company is NRF framework of the procedures, nrf organization is the ultimate reference document, I understand there are a number of documents, if there are problems, So this is the only document to help you.
