of transmission products and provides interfaces such as Ethernet over SDH and CWDM. Therefore, R8000 can use a single device to implement the functions of multiple devices, maximizing the cost of network construction and maintenance for operators. R8000 adopts the network processor-based distributed forwarding architecture and has fully programmable capabilities. It can implement flexible service generation and customization functions and provide ne

service ports of the aggregation Layer Nodes and reduce network costs. At present and in the future, the TDM business will remain the most important source of revenue for telecom operators, and there is still room for growth. When the business needs are dominated by TDM business, create a convergence layer for the Metro Transmission Network to use MSTP. If the existing SDH network still has a large amount of remaining capacity, it can meet the needs of future TDM business development, and when

is also the main working band of the current practical optical fiber communication system. The main parameters of 1310nm conventional single-mode optical fiber are determined by the ITU ITU-T in G652 recommendations, so this kind of optical fiber is also called G652 optical fiber. As mentioned above, because of the absorption effect of OH peaks (Water peaks), 900 ~ 1300nm and 1340nm ~ There is a loss peak in the 1520nm range, which is called a water peak. Currently, the TeraSPEEDTM zero-water p

Introduced the SFP + module version of optical fiber and copper core, Compared with the Xenpak, X2, or XFP version of the module, the SFP + module retains some circuits on the main board, rather than in the module. SFP type SFP transceiver has a variety of different sending and receiving types. You can select an appropriate transceiver for each link to provide available optical fiber types (such as multimode or single-mode

require long-distance, high-density, GB embedded optical connections. MSA uses coarse Wavelength Division Multiplexing (CWDM) technology to provide four 25G Single-Mode Optical Fiber (SMF) link channels. Similarly, the OpenOptics MSA organization launched by Ranovus and Mellanox Technologies will focus on developing a data center that supports 2 km and GB. In the past, the speed improvement promoted the development of most network components. Today,

interoperability. In short, where fiber resources are scarce, where can be used WDM transmission system, not only to solve the problem of resource shortages, but also can greatly solve the rental of optical fiber or laying optical cable more cost savings. Next, I will give you a few very typical WDM transmission system application scenarios. 650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M01/6E/FE/wKiom1WOTjSBaqjwAAEu6ILl5JI543.jpg "title=" Point-to-point wavelength division multiplexin

three kinds of RPR, manufacturers have introduced the corresponding products. The independent 2-layer RPR implementation scheme is mainly applicable to the access layer and the aggregation layer of IP metropolitan Area Network, and is the most mature solution at present. Some manufacturers combine multiprotocol label Switching (MPLS) technology, clock synchronization technology, CWDM technology and TV video broadcasting technology with this 2-tier im

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

SFP Gigabit Ethernet ports can be installed with a wide range of SFP transceivers including CISCO1000BASE-SX, 1000BASE-LX, 1000BASE-BX, 1000base-zx, 100base-fx, 100base-lx10, 100BASE-BX and coarse-wavelength division multiplexing (CWDM) SFP transceivers.

The E-pon system is composed of Olt (optical circuit terminal-optical line termination), ONU (Optical Network Unit-optical Network) and fiber wiring unit, and the system uses Ethernet protocol. We call the downlink signal from Olt through 1:n optical passive splitter to ONU, from ONU to Olt for uplink signals. The data of the E-pon system is transmitted through an indefinit

The PON technology uses a point to a multi point topology, and the downlink light signal emitted by Olt is broadcast through a passive optical
