What are the optical transceiver suitable for metropolitan area networks and access networks?
With the rapid development of industry informatization, the demand for long-distance and large-capacity bandwidth has increased rapidly, resulting in rapid growth in traffic at the access layer, metropolitan layer, and backbone network.Optical transceiver also need to be continuously upgraded to be ideal for more advanced network environments. So what are the optical transceiver suitable for metropolitan area networks and access networks?
What is a metropolitan area network?
The metropolitan area network is located between the wide area network and the access network. It is a computer communication network established within a city and belongs to a broadband local area network. Due to the use of geographic area network technology with active switching elements, the transmission delay in the network is certainly small. Its transmission medium mainly uses optical cables, the transmission rate is normally above 100 megabits/second, and the coverage range is generally between 200-400 km.
Sometimes, people believe that the metropolitan area network is a small-scale wide area network, but the two are significantly different in some respects. First, the coverage region of the metropolitan area network is much smaller than that of the wide area network; second, the network topology structure of the metropolitan area network often changes, and the network topology structure of the wide area network is more stable; finally, the metropolitan area network is the most The complex application environment must support a variety of services and services, including traditional voice and private line services, data storage, video transmission, and distributed services. The WAN is a backbone network that is mainly used to implement Interconnection of local area network or metropolitan area network. In general, the metropolitan region network, as the connection point between your wide area network and the access network, must not only meet the increasing bandwidth requirements of the wide area network, but also support multiple high-speed access technologies.
What is an access network?
The so-called access network refers to all the equipment between the backbone network and the user terminal. Its length is normally several hundred meters to several kilometers, so it is called the "last mile". Since the backbone network generally uses an optical fiber structure and the transmission speed is usually fast, the access network becomes the bottleneck of the entire network system. The access methods of the access network include copper wire (ordinary telephone line) access, optical fiber access, fiber coaxial cable (cable TV cable) mixed access, wireless access and Ethernet access.
Based on this, DWDM (Dense Wave Length Division Multiplexing) technology plays an essential role in metropolitan area networks and access networks. DWDM technology can make full utilization of the huge bandwidth resources of optical fiber, greatly boost the transmission capacity of the system, and reduce the transmission cost. Therefore, this technology offers been widely used in long-distance and ultra-large capacity transmission in the backbone network. If DWDM technology is introduced into the metropolitan area network and access network, the whole network will become a seamlessly connected whole, providing support and connection for all different services. Therefore, the DWDM system in the metropolitan area network provides great advantages and The development potential can be the inevitable evolution of the entire communication network to the all-optical network.
The 100G, 40G, 25G, 10G, 2.5G, 100M and mobile fronthaul networks for metropolitan area networks and access networks have corresponding metropolitan area network and access network optical transceiver. Among them, CFP/CFP2/CFP4 and QSFP28 optical transceiver are ideal for 100G, QSFP+ optical transceiver are used for 40G networks, and 25G SFP28 optical transceiver are preferred for 25G networks. 100M, 2.5G, 10G optical transceiver and mobile fronthaul optical transceiver are available in a variety of packages.
