In 2020, 5G network began to be tested in developed cities, and 25G SFP28 optical module was also applied in the construction of 5G signal base station. The 25G SFP28 optical module is not only used in 5G network, but also widely used in 25G data center. The best input/output (I/O) performance and fiber capacity of the 25G SFP28 optical module are 2.5 times of the performance of 10G Ethernet, and ...
With the increasing demand for data transmission, the traditional 10G Ethernet can no longer meet the modern transmission requirements. Because of the high deployment cost of 40G/100G Ethernet network,25G Ethernet has become a good transition scheme. In the construction of 25G network, 25G SFP28 optical module has become a good solution. Next, yitianguang communication will introduce a kind of opt...
The Cisco Nexus 9000 series switch is designed to meet the increasing demand of users and complex applications in the data center. It not only supports ports with 10/25/40/100G transmission rates, but also supports 16/32G fiber channel, Ethernet RDMA (RoCE) and IP storage unified port. The Cisco Nexus 9000 series switches include the Nexus 9500 modular switch and the Nexus 9300 non modular switch....
At present, 5G has started the commercialization process, but the complex bearer scheme leads to the increase of the corresponding optical module types. For 5G forward transmission, in terms of speed, AAU has introduced the eCPRI protocol standard, and the forward 25G rate has become the standard of various equipment manufacturers. Because of this, the rate standard of the carrier network will be ...
Metropolitan area network is a computer communication network established within a city, referred to as MAN. It is a broadband local area network. Due to the local area network technology with active switching elements, the transmission delay in the network is small, and its transmission medium mainly uses optical cables, and the transmission rate is above 100Gbit/s. An important use of MAN is for...
2020 is the first year that 5G will be commercialized. At present, 25G optical modules have also been used in the construction of 5G signal base stations. Among them, 25G CWDM optical modules have a high market prospect in 5G fronthaul. Compared with other 25G optical modules, 25G CWDM optical module can save more fiber resources, thus effectively saving the total cost of operators. As early as 20...
With the increasing demand of data center for bandwidth, the network rate is developing towards a higher rate, and there is bound to be the need for network upgrading. There are two upgrade paths for the network from 10G to 100G, namely 10G-25G-100G and 10G-40G-100G. End users seem to prefer 25G. Why? ETU-LINK will tell you. All this can be said from the rise of 25 Ethernet. Data center TOR...
Now various industries are gradually inseparable from the existence of electricity, because every kind of electrical appliance needs electricity to operate. But once our phones, network video and wireless routers are out of power for no reason, where should we find a suitable power supply system? So the poe switch appears, a typical Ethernet power supply system, which is better suited to the ...
