OTN switching P-OTN effectively reduces network cost by 100 GB (2)
Globally, the growth rate of mobile and Internet traffic is unprecedented. The reasons for this phenomenon include the growth of cloud services, mobile broadband, and Internet-based on-demand video streaming services. Cisco predicts that from 2012 to 2017, Internet IP traffic will triple to 120 bytes per month, and mobile data traffic will
to 10 Gbit/s OOK receiver tolerances (typically +/-400 ps/nm ), in this range 100 Gbit/s PM-QPSK EDC is easy to achieve.
C. polarization modulus dispersion (PMD) margin
An EDC modem chip can also be used for the compensation of PMD. One of the key aspects of PMD compensation is that it is necessary to track the changes of High-Speed polarization dynamics on the network very quickly. This is very different from the dispersion compensation, because the dispersion changes are relatively static (th

High-density and highly integrated OTN Wavelength-Division transmission SystemThis wave division multiplexing technology in the heyday, a variety of new technologies emerge. The goal is the same, that is to meet the network era of the operators. Long long ago, can only use CWDM coarse wave points, channel number is not enough to say, transmission distance is also very limited, line and equipment attenuation calculation,10G no relay transmission Kilo
deployment, this solution also causes a large amount of idle network bandwidth.
From the operational perspective, both solutions are not ideal. The client service is not only bound to a specific uplink wavelength, but also because the ROADM-based network can only be switched according to the whole wavelength, any network configuration at the business layer, if the client is re-routed or the network is re-optimized, the operator must dispatch technical personnel to the site for manual operation.

Unlike the Sdh/sonet basic 8K frame cycle, with the increase of the line rate, the structure and length of the g.709 frame are constant, and the frame cycles of different rate classes of OTN are not the same.OTU1 48.971usOTU2 12.191usOTU3 3.035usThe frame rate of OTN is specifically designed for SDH, where OPUK frames can be fitted with SDH frames of the same rate grade

With the development of enterprises to a certain stage, with the needs of customers and the needs of their own management, many enterprises have successively performed ISO quality system certification and ERP resource system activation, in addition, the Rules and Regulations previously formulated by the enterprise form a state in which three management systems are in parallel. However, since each management system has its own characteristics, the aspe

I would like to recommend a book on embedded entry: Embedded System Design (Chongqing University Press, author Peng ). I have also made some good looks recently. I have summarized some of the embedded knowledge we learned before, as well as the operating system and composition principles, this is a summary of the knowledge learned in this book and a review of the previous knowledge.
I personally think that the learning of embedded systems should be co
