than the protection channel provided by the SDH system for traffic signals such as GBE, which transmit large particles. From the above two aspects is not difficult to see, when the network of operators in the optical fiber resources are relatively tight, and the network has a large number of data service transmission requirements, the use of Metro DWDM system to build core optical network is a very ideal solution. It is noteworthy that in the transport interface layer, the transport access la

. In recent years, the new San over CWDM (coarse wavelength division multiplexing) solutions, such as the Ciena CN 2600 products, provide the best transmission performance, but also solve the high cost of DWDM, in the area of storage expansion has been widely used. SAN over IP solutions enable organizations to leverage their existing virtual private network (VPN) or public Internet delivery storage network business. Due to the high latency caused by

FTTD (Fiber to the Desk) cabling scheme is attributed to the overall FTTx system, FTTD as a high-level solution for cabling systems, the industry is well aware of the excellent transmission performance of fiber as a transmission medium, but also due to the high price of optical fiber active equipment, Led to few projects in the past few years large-scale use of FTTD wiring. In the rapid development of FTTX access network today, especially the development of FTTH networks, due to the overall indu

function, supports VLAN division, and provides redundant power interface. Although for layer-3 Switch, DES-3326 performance in general, support expansion slot is relatively small, but the low price is also in exchange for good cost effectiveness. DES-3326 switches are suitable for medium and small network core layer and large campus network convergence, providing Gigabit Ethernet modules can be connected to high-speed backbone network, to effectively alleviate network bottlenecks.

In addition, you can use NETGEARNMS100 network management software based on the SNMP protocol to centrally manage all network management switches and these smart switches in your network. Like All NETGEAR products, all ports in the ProSafe smart switch series support AutoUpLink™Adaptive and self-Negotiation means that you can achieve maximum performance without using dedicated cables, so that your network investment can adapt to industrial standards-and support any

It can establish direct point-to-point connections between ports, which is good for single-point transmission performance, but not suitable for multi-point transmission. The third is the hybrid cross-bus structure, this is a hybrid cross-bus implementation method. Its design idea is to divide an integrated cross-Bus Matrix into small cross matrices and connect them through a high-performanc
