PMC Release DIGI-G4 targeting metro network 400G OTN switching

Recently, PMC officially launched the industry's highest density single-chip n × 10/40 / 100G of DIGI-G4 OTN processors. It is reported that, DIGI-G4 to capacity (P) -OTN line card expansion to four times, and the power consumption per port decreased by 50%. In addition, DIGI-G4 via low-latency 100G OTN encryption to protect the security of cloud data and provide flexibility from 1G to 100G bandwidth expansion on-demand services.

Kevin So PMC Communications Products Division, senior product manager, told reporters on the market using multiple FPGA-400G line card, it will call multiple devices, high power consumption, to reduce the power consumption can only make sacrifices in functionality such as reducing the number of channels, customer types of restrictions. The single chip can bring greater scalability and performance, such as a single device can complete 4x100G OTN carding and exchange, and to achieve in the case of non-destructive function reduces power consumption by 50% per port.

In addition, DIGI-G4 OTN also provides cloud and SDN design innovative solutions. DIGI-G4 OTN uses the industry's first sub-wavelength OTN encryption technology. Kevin So said the traditional OTN wavelength level encryption only supports a single network client and point to point architecture, DIGI-G4 is OTN sub-wavelength level encryption, support for multiple network clients OTN switching and network architectures.

In addition, DIGI-G4 can help achieve new data center WAN transmission platform. Kevin So expressed, DIGI-G4 is a highly integrated SoC, safe, low power consumption, and data-center applications optimized, its "rack & stack" can effectively extend optical bandwidth WAN. DIGI-G4 also provides operators get certified OTN switching SDK. "DIGI SDK has been in China, North America and Europe has been field-proven, the fact that it not only reduces equipment expenses for research and development, but also greatly shorten the time to market." Kevin So said.

In KevinSo opinion, PMC developed chip will effectively support the rapid development of global broadband market. "IP video and data centers by the impact of the rapid development of cloud and other services, is expected in 2013 - 2017 Metro traffic will grow more than four times, which makes more enthusiastic countries operators to deploy 100G network bandwidth utilization rising further. "Kevin So said.

"100G + OTN switching + security" has become a popular metro network infrastructure, fiber capacity can be increased by 10 times, to enhance the utilization of fiber resources for more than 40%, so the deployment of 100G for operators is very favorable. Currently the world's ten largest operators, there are nine in the deployment of OTN switching network.

"China is deploying 100G and OTN switching fields are leading the world, China's three major carriers all deployed 100G and OTN switching technology." KevinSo said, "in 2014, only China Mobile to deploy a 100G OTN ports will account for about 25% of the global total, China's telecommunications manufacturers have introduced a scalable 100G OTN switching products.

" In March 2015, Premier Li Keqiang announced a landmark "Internet +" initiative, plans to promote the cloud, things have become China's next growth engine. To this end China's State Council has explicitly requested to improve China's backbone optical network, it is foreseeable that China will be accelerated to MAN 100G OTN replacement. KevinSo believes that China is bound to consider the next step carriers upgrading to 400G, 400G is converged packet per slot and OTN switching platform (P-OTN), and a compact, secure, optimized for data center interconnects 100G solution, which means the communication industry, a huge business opportunity.

Kevin So pointed out that the industry is now faced with the same problem that the existing infrastructure is based on 100G design, and must be in the same frame size and power base conditions required to support 400G. "Every slot capacity upgrade from a previous 100G to 400G, can not be increased while the size of the line card, power consumption must be reduced by half, continue to use conventional processor can not be achieved." Kevin So said, "DIGI-G4 is the In order to solve this problem and launched, it can help communications companies achieve a series of design requirements. "
