The new solution increases the connection capacity to 10 times, integrated link security.
And also support 4G and 5G wireless C-RAN
Committed to providing a leading supplier of differentiated semiconductor technology solutions in power consumption, reliability, and performance (Microsemi Corporation, New York Nas): MSCC) announced the launch of new mobile pre-transmission solutions This solution is based on its DIGI-G4 optical transmission network (OTN) processor series, which will achieve higher capacity pre-transmission connection to the fusion 4G and 5G centralized wireless access network (C-RAN). The solution creates a primary river, extending 100G OTN to RAN, can simultaneously aggregate high-density universal public wireless interface (CPRI), 10GE, and 25GE access. It also achieves an increase in capacity of up to 10 times, and introduces various innovations, using automatic link balanced response requirements and response to network security requirements.
Mobile operators from all over the world are developing their RAN from the distributed base station to the centralized base station (C-RAN) mode, so that the economically efficient increases mobile capacity, and prepares for 5G. According to market research firm IHS report, by 2020, C-RAN deployment will grow at a rate of 23% per year, accounting for more than 60% of 4G RAN within this time frame.
As mobile operators continue to add new LTE-Advanced (LTE-A) functions in their existing 4G network, such as carrier aggregation and higher levels of multiple (MIMO), and use small cells to increase density, so that the interconnection between the CPRI radio heads distributed and centralized base station needs to be expanded four times the data rate reaches 10G. As the industry is moving toward 5G, it is driven by 5G RF head-intensive 25GE Ethernet connection, the pre-transmission connection will need to be extended to 200Gbps.
Babak Samimi, Vice President and General Manager of Mei Gaosi Mei Communication Business, said: "With mobile operators to increase capacity demand, C-RAN is becoming their preferred network architecture, but so far, due to lack of economic efficiency and optical fiber Efficient way to build a prequel network, hinder the mobile industry into C-RAN. As the ecosystem continues to carry out 100G fiber cost optimization, plus our Digi-G4 integration unique innovation, Mi Gao Senmei has launched quite attractive The solution to deal with the prequel network challenge, not only significantly increase the fiber capacity, but also allows operators to push C-RAN deployment in the unified architecture, seamlessly transition from 4G to 5G. "
It is different from the traditional wave division multiplex (WDM) solution that allows each WDM to connect to a radiographic head, Mi Gao Mi Mei Digi-G4 OTN preparatory architecture allows multiple 4G or 5G access to more than 100G OTN connections, making capacity 10 times more than the existing fiber infrastructure. Through the embedded fiber link security engine, integrated real-time connection time extension (patent audit) and the simultaneous support of 4G CPRI and 5G Ethernet protocol implementation differentiation, Mi Gao Senmei is promoting the capital expenditure of mobile operators to build ahead of the network (CAPEX) And the redefinition of operating costs (OPEX).
Dr. Li Wei, deputy director of the Network Technology Institute, China Mobile Communications Research Institute, said: "For a long time, US Gao Senmei has always been the key enabled of China Mobile to deploy 100G OTN switching technology in its urban area and long distance network. We are very happy Seeing Mi Gao Si Mi offers low-cost, low-delay, high-capacity and adaptation technology in its DIGI chip series, extends its OTN leaders to 4G OTN prequel network, and actively for 5G OTN Prequel network is prepared. "
