Applications And Solutions

Applications Of WDM In Single Fiber Bidirectional Transmission
Scene Description:
Due to the absence of their own optical fibers, the interconnection between government centers and enterprise parks mainly adopts the way of broadband renting currently. But as the growth of the broadband requirements, the demand of renting the bare fiber for self-built wavelength division load network have increased. In order to further save network construction costs, a new solution is proposed to construct large-capacity wavelength division based on the single fiber bidirectional technology.
Case study: the interconnection between government centers, single fiber bidirectional wavelength division transmission network.

Highlights In The Solution:
1.Single fiber system supports 10G transmission, which makes a good solution to the contradiction between optical fiber and broadband;
2.It supports 100M~10G full-service access;
3.Physical isolation between the services, and dedicated network for special purpose;
4.Metro fiber cable loss is generally high and the system can be configured with optical amplification to solve the problems of long distance transmission and fiber loss;
5.1U equipment can meet the service requirements, because it’s flexible, plug-and-play, free-of-configuration and maintenance free.
Applications of WDM transmission networks for disaster tolerance backup
Scene description:
With the construction of the data center construction for private network clients from such as cloud network, IDC and big enterprises, the demand for the disaster tolerance backup system demand is increasing. Clients choose the self-built wavelength division method to solve the contradiction between the fiber and large broadband which not only can improve network reliability by “private network for special purpose” but also achieve high-broadband service transmission and even meet the flexible extension of long-term service.
Case study: wavelength division transmission network of enterprise disaster tolerance backup (1+1 hot standby)

Highlights in the Solution:
1.The most comprehensive IP and SAN service interface, which supports almost all of the IP and SAN services at present;
2.The scope of disaster backup expands to 130 km, meeting the demand of the large volume of disaster backup for multiple physical nodes;
3.1+1 backup protection for wavelength division hardware and line achieves the highest network protection.
Applications of OTN transmission bandwidth cloud
Scene description:
With deepening of informatization in the industry, larger-particle Ethernet services have been gradually rising, which leads to the fast growth of the traffic in the access layer, metro area layer and backbone network. Therefore, the construction of the multiple service transmission platform and the provision of high capacity channel has become a new development direction for the transmission network technology. The solution of “OTN transmission broadband cloud” is just born for this. The “OTN transmission broadband Cloud” is a blend of advanced technology of 10G~100G and large capacity OTN photoelectric cross. Just like the “cloud computing”, it has formed a large-capacity, dynamic shared, quickly accessible, intelligent and reliable network.

Highlights in the Solution:
1.Construct the large volume pipe with the 100G technology, and allow the entire network to share 100G broadband channel via OTN technology at the same time;
2.Meet the scheduling demand for large capacity and flexible network, support 40->80 wave or 10G->100G modular expansion, ensure the network to smoothly upgrade to 8T massive transfer, which not only saves the initial investment but also satisfies the future network development for many years;
3.OTN transmission broadband cloud solves the industry various clients’ challenges in the industry planning, construction, maintenance and other aspects and brings the client a experience of “zero waste large broadband, rapid release and zero waiting, and zero service interruption”
4.Unified management, intelligent network management, real-time monitoring of network running status all guarantee the stability of the network.
Applications of WDM unidirectional transmission network
Scene description:
Big data era is formally arriving with the development and popularity of the age of the Internet, the core of the construction of the cloud services based on large data is to conduct data collection and analysis in order to show the value of the data. Because of the network various sources and huge amount of the data, the large-scale network data analysis platform is usually established in equipment room in non-local locations. The WDM unidirectional transmission solution can provide real-time, reliable, safe and stable data transmission for non-local network data analysis platform.

Highlights in the Solution:
1.It supports 100M~100G full-service access, all types of services can access system, and they are all transmitted on a single fiber by multiplexing;
2.It supports the transmission upon the expansion from 40 wavelength to 80 wavelength or the convergence from 10G to 100G, which maximizes the use of fiber core and channel resources;
3.Network transmission signals and service signals are jointly transmitted to the pretreatment equipment room, so as to realize a unified network for the entire network equipment.
