Sun Jian introduced, "The new generation of OTN boutique optical network", with ultra-fast opening, bandwidth on demand, ultra-low latency, super large speed, ultra-high reliability, ultra-wide coverage, business visibility, cloud network integration eight characteristics, through physics The isolated transmission network provides end-to-end active and standby multiple protection, and the network reliability exceeds 99.99%, helping the government to build a digital transformation infrastructure.

China Telecom guarantees the opening of a new generation of OTN boutique optical network within seven working days. The equipment procurement can be completed within three working days, and resources are opened at the minute level. At the same time, the bandwidth is optional and can be flexibly adjusted. China Telecom provides self-services for business portals, and products provide the same business portals. Customers can adjust the service bandwidth on-demand according to the requirements of the portal.

In terms of delay, China Telecom upgraded the backbone segment by 10-15% through the upgrade of the underlying optical network technology; it was upgraded through network equipment. In the metropolitan area network, the low-bandwidth delay can be reduced by more than 50% through large-particle encapsulation. Through the backbone to the channel, the one-way delay between the cities will be less than 5ms/1000Km. The local one-way delay of 13 cities is less than 1ms.

The new generation of OTN boutique optical network has both super-fast speed and full compatibility. Network resources have more 300T network capacity, which is equal to 120,000 2.5G bandwidth services. The transmission capability is also stronger. The "100G maximum rate" is equivalent to the SDH service. The maximum bandwidth is 100G, which is 40 times higher. The entire network provides 2M-100G end-to-end channels for full-granular load. Comprehensive access methods: STM1/4, 16/64; FE/GE/10GE/100GE and so on. The product supports SDH/Ethernet/OTN multiple access modes to ensure flexible access and good compatibility.

In terms of safety, China Telecom's next-generation optical network adopts multiple protections, which is ultra-high reliability. The entire network provides 99.99% availability; multi-circuit combination can achieve 99.9999% super high availability. More technical means, more protected content, 50ms automatic recovery, compared to the WDM service, with end-to-end 1+1 protection, 50ms automatic recovery.

The new generation OTN boutique optical network adopts flat networking, backbone + local two-tier architecture. The whole network covers 128 cities in one phase, and can supplement the end-to-end capabilities of 244 cities in the network channel as needed, and gradually extend to the whole country. The international OTN network has reached 21 cities and achieved global coverage.

In terms of cloud network convergence, China Telecom's OTN boutique optical network has been fully integrated into the national Tianyi cloud resource pool and IDC engine room, combined with the cloud network integration operation system, providing one network access and cloud network integrated service.
