Highly Integrated DCI Arithmetic Network Solution

As global AI and cloud computing continue to evolve, the proportion of east-west traffic between data centres continues to rise. According to IDC forecasts, the average annual growth rate of global data centre traffic has reached about 30%, and DCI networks are facing three core challenges:

• Space and energy consumption constraints: traditional stacked equipment occupies multiple racks, 400G system power consumption of more than 60~100W per link, energy consumption pressure;

• Lack of scalability: discrete optical modules and electrical layer equipment tightly coupled, upgrading the need to replace the entire set of link equipment, the deployment of the cycle is long;

• operation and maintenance complexity: multi-vendor equipment mixed deployments, patch fibre connectivity is complex, locating faults is time-consuming, MTTR is high.

The OTNS8600-P series device independently developed by Sintai's team adopts a 1U high-density design with built-in optical modules, electrical layer processing and scheduling capabilities, which gets rid of the traditional wavelength division stacked connectivity and simplifies the deployment of patch fibres, and is an ideal wavelength division interconnection system for arithmetic networks with high-integrity, high-reliability, and minimalist management features.

1. Compact and energy-saving design, optimizing deployment space and power consumption

• High-density packaging: 1U supports 12×400G full-duplex interfaces, with a bandwidth density of up to 4.8Tbps/U, saving space in the server room;

• Low-power module: adopting a high-integrated optoelectronic encapsulation scheme, the power consumption of the 400G module is better than that of the traditional discrete design, which helps reduce the energy consumption of the whole machine;

• Intelligent energy-saving: based on the traffic prediction, it can shut down the idle channel, improving the performance of the whole machine's energy efficiency.

2. Highly reliable optical-electrical synergy, guaranteeing the stability of key services

• Ultra-low-latency links: optical-electrical synergy design reduces signal conversion links, end-to-end delay <1μs, meeting the demand for financial-grade interconnections;

• High-reliability architecture: supporting FEC error correction, FlexE slicing, and link redundancy and inversion, with a strong ability to ensure business continuity;

• high availability of whole machine design: supporting hot-swapping of modules and fast fault recovery, improving the efficiency of MTBF and MTTR.

3. Open management and full lifecycle optimization

• On-demand opening capability: supporting 12 ports to be opened flexibly, customers can deploy in phases according to the development of bandwidth to reduce the initial investment;

• Intelligent visual operation and maintenance: supporting Web network management, OSC in-band communication, and open interface of SNMP to facilitate centralised management;

• Future-oriented evolution: the system can be upgraded to 800G capacity and support higher-order modulation format to meet the future evolution of computing demand.

4.Typical scenarios and application values

Sintai will continue to promote the product upgrade of 400G/800G integrated transmission platforms to help customers build low-power, high-density, high-reliability future DCI networks.
