IPoDWDM-Open Line System Solution

Under the wave of global digitisation, optical networks are undergoing profound changes, driving evolution towards openness, intelligence and greening, with multiple trends driving this transformation:

• AI and high-performance computing boom: single GPU cluster training needs to synchronize petabytes of data, and traditional closed systems are difficult to support rapid expansion;

• Cloud computing and multi-cloud architecture popularity: east-west traffic across data centres is proliferating, requiring flexible, open, high-density optical interconnection solutions;

• Edge computing rise: small edge nodes are putting forward new requirements for low-latency, high-bandwidth connectivity, and the traditional backbone network architecture is no longer suitable for it;

• Content distribution and video traffic explosion: ultra-high-definition video, AR/VR and other applications push up the demand for last-mile and metro network bandwidth;

• Green energy-saving policies: global operators accelerate network energy-efficiency transformation, and low-power, high-density equipment becomes the mainstream choice;

• Open decoupling trend: OpenROADM, OpenZR+ and other standards promote the optical network from a closed system to an open interoperable architecture evolution.

In the face of this series of challenges and opportunities, the Open Line System (OLS) has emerged as a key choice for cloud service providers, carriers, and large-scale data centre construction. Sintai's independently developed OTNS8600-OLS device adopts standardised interfaces and decoupled architecture, separating optical transmission equipment, optical modules, and control software to achieve multi-vendor interoperability, effectively breaking down closed-system constraints and helping customers build sustainable and scalable network infrastructures.

1.Full-stack open, no vendor lock-in

• Flexible configuration: 1U rack supports 100~400G mixed insertion, can use Sintai or third-party optical modules, flexible investment, reduce procurement costs;

• large-capacity transmission: 1U supports 48 channels, the maximum transmission capacity up to 19.2T;

• Plug-and-play: automatically adjust the optical power and wavelength, no need for complex debugging, simplify the deployment;

• Controllable and visible: support for monitoring and controlling the power of each channel, fibre distance and loss measurement, locate faults more efficiently;

• High reliability: support for 1+1 protection of optical cable to ensure business continuity;

• Low power consumption design: the whole machine power consumption <150W, in line with the trend of green energy saving;

• Easy deployment: 0~120km intelligent optical channel auto-configuration, releasing manpower, reducing operation and maintenance costs;

• Intelligent management: support for Web GUI, B-S centralized management, open SNMP interface and OSC in-band.

2.Future layout of open optical networks

Sintai's next-generation 100G~800G open line sytem and 1~400G systems with fewer wavelengths for small and medium-sized companies are under close development and are expected to be officially launched in 2026. Here are our future directions of attack based on current industry characteristics.
