system to the 100 Gbit/s OTN system, the following requirements must be met: 1) supports 50 GHz channel spacing; 2) dispersion (CD) margin ± 700 ps/nm; 3) polarization modulus dispersion (PMD) margin of 10 ps (DGD average value ); 4) It can be smoothly upgraded in the existing DWDM network and OTN network; 5) there is no major crosstalk cost for existing DWDM channel signals. 100 Gbit/s OTN system upgrade

connected to the optical network cannot change significantly. Even by 2017, services with 10 Gbit/s or lower end-to-end management will still occupy over 95% of the access ports in the optical transmission network [IV]. The transition to 100 Gbit/s DWDM wavelength causes a large number of rate mismatch/discontinuous problems between Client Services and WDM uplink ports, resulting in a large amount of inefficient use of optical bandwidth. Multiplexing

Ethernet switches are expanding their applications to the network core. This is mainly from two aspects: one is that Ethernet switches have the function of routers, not even, there are more than three layers of switches; the second is the maturity of the physical layer technology and the Exchange technology makes the Ethernet break through the area of the LAN, and can implement the network across a wide range of regions, such as Single-mode fiber transmission distance can reach more than 40 kilo

crossover products based on Sonet/SDH continued to drop by 2013 in 22% to $0.2 billion. From these figures, we can see some obvious trends: G is driving the growth of core network spending and affecting the decision-making process of carrier's core network architecture. At present, OTN is the clear choice of the carrier's core network, and we believe it will continue in the next five years. The operator hopes to combine their own otns with the transmission platform. This is also the case in the

Application of single channel 10G Wavelength Division transmission SystemInternet has become an indispensable tool for Gaga households, because the network era, People's happiness index is more and more high, the rate of Internet broadband is more and more high, the trend determines the network needs to be reformed.
