Huatai Futures Builds A Low-Latency and Reliable DWDM Network with FS Mux Demux

Founded on March 28, 1994, Huatai Futures is one of China’s first futures companies. It has established 9 branch offices in Beijing, Shanghai, Shenzhen, Guangzhou, Chengdu, Dalian, Zhengzhou, Hangzhou, and Nanjing, along with 42 business departments and over 200 outlets nationwide, forming a comprehensive service network.

As the company’s data center traffic continues to grow, Huatai Futures successfully addressed challenges such as link loss, upgrades, and expansion costs by deploying the FS DWDM solution. This solution not only reduced transmission link loss and operational costs but also enabled flexible network expansion and upgrades, ensuring the company’s data center network can support its future business growth and sustainability.

As data traffic and business demands continued to grow, Huatai Futures' expectations for the reliability and stability of its data center services also increased. Currently, each data center involved operator room handovers, fiber splicing, and multiple nodes, resulting in significant link losses that impacted data transmission speed and quality. This became especially problematic during peak periods, when network congestion and performance degradation led to packet loss and network outages, increasing the risk of data breaches, threatening network security, and reducing business efficiency and market competitiveness.

Additionally, the existing data center network had limitations when it came to future upgrades and expansion, making it difficult to meet the increasing demands for higher data transmission rates and business traffic. To expand data center capacity, Huatai Futures had to invest heavily in new hardware, infrastructure upgrades, and increased bandwidth. This not only raised operational costs but also presented challenges in balancing performance with cost-effectiveness.

Furthermore, the rapidly changing financial market made the solution delivery timeline crucial for Huatai Futures' investment and trading opportunities. Long delivery times could have resulted in missed business opportunities, impacting project decisions and market positioning. In times of market volatility, delays could have caused Huatai Futures to lose its competitive edge. As a result, optimizing and upgrading inter-data center links became a critical priority.

After a comprehensive evaluation, Huatai Futures implemented FS DWDM solution to address link loss and expansion challenges in data center transmission. By building a high-availability, low-latency DWDM network, the solution enhanced business continuity and provided a strong foundation for future growth.

The solution centered on a 4dB low insertion loss, 100GHz single fiber DWDM Mux Demux, paired with a 16 channel DWDM Mux Demux (C45-C60 wavelengths) that worked with the transmission wavelengths (C21-C36). The system multiplexed 8 channels on OS2 single mode patch cable, utilizing reverse-direction transmission and reception. This optimized fiber resource use, reduced multi-node hops between the data center and operator room, lowered link loss, and improved transmission efficiency and quality.

To ensure link integrity, low power consumption 1G DWDM SFP+ and 10G DWDM SFP+ optical modules with C21-C24 and C45-C48 wavelengths were used for 4-way transmission at both ends (A and B). This ensured device interoperability, met current network demands, and reserved space for future network expansion and upgrades. This progressive upgrade strategy reduced initial construction costs while ensuring long-term availability and performance.

Additionally, through a rapid 14-day deployment, Huatai Futures optimized its data center links, ensuring stable operations and enabling it to seize key investment and trading opportunities. The optical modules, tested for compatibility and performance, ensured low-latency, high-performance connectivity, laying a solid foundation for future growth and strengthening Huatai Futures' competitive position in the industry.

Through 1-to-1 online technical support with FS, Huatai Futures received a high-availability, low-latency data center interconnection solution within 0.5 days and completed project delivery and acceptance within 2 weeks.

By following FS professional link optimization recommendations, Huatai Futures deployed low insertion loss DWDM Mux Demux within the DCI network. Using WDM technology, the solution enabled parallel transmission of fiber resources, reduced multi-node hops in the link, and significantly lowered overall loss, improving transmission efficiency.

Huatai Futures applied FS scientific optical module selection, flexibly deploying low-power DWDM optical modules with corresponding wavelengths at both ends of the transmission link. This approach seamlessly connected 1G to 10G, fully compatible with the data center DWDM Mux Demux, effectively reducing operational costs.

By deploying FS DCI solution, Huatai Futures not only met the current network traffic growth and transmission demands but also enabled smooth expansion and upgrades of the data center network through DWDM devices, ensuring support for the sustainable development of future financial business.
