On June 28, 2022, China Telecom issued an announcement "China Telecom Beijing Research Institute 2022 Gray Box Transmission Equipment Management and Control System Function Module Development Project Comparison and Selection Announcement".
Telecom metro WDM/OTN network opening decoupling , continue to advance! The
announcement mentioned the project background:
In recent years, optical network equipment and its management and control technology have continued to develop in the direction of white box and SDN, laying the foundation for building an open and decoupled optical network .
China Telecom's "All-Optical Network 2.0 Technical White Paper" puts forward open and decoupled network architecture requirements for metropolitan area transmission network. With this goal, China Telecom is developing the gray box transmission equipment management and control system to enhance the optical network. Ability to control oneself. Part of the interface development, non-core function development, interface adaptation and test joint debugging of the
gray box transmission equipment management and control system are planned to be solved through this procurement project.
The open decoupling work of telecommunications optical networks is in a leading position among global operators. We have also been paying attention to:
- On September 8, 2021, China Telecom released the "China Telecom Beijing Research Institute 2021 Gray Box Transmission Equipment Management and Control Platform" Development Project Winner Announcement", the winner is determined to be: Kaitong Technology Co., Ltd. .
- In November 2021, China Telecom released the " China Telecom All-Optical Network 2.0 Technical White Paper ", which provided a comprehensive and systematic explanation of the open decoupling architecture of optical networks.
- On January 20, 2022, China Telecom released the "China Telecom 2021 Access OTN Equipment Unified Management and Control System (UMS) Construction Project Single Source Procurement Announcement". China Telecom System Integration Company won the bid.
- In February 2022, China Telecom Beijing Research Institute conducted a public comparison of the open optical network equipment customized prototype development project. The main evaluation product category involved was DCI-BOX.
- On April 13, 2022, China Telecom released the "China Telecom Wave Division Equipment Customization (2022) Procurement Project Pre-Qualification Announcement". independently developed and deeply customized wavelength division equipment is the first time in the industry for operators to independently develop optical networks!
- On March 29, 2022, telecom optical network experts revealed in an interview that box-type DCI wavelength division will be used in metropolitan area , and the box-type wavelength division series products will support the large-scale deployment of new metropolitan area networks for enterprises in 2022.
What Telecom purchased this time was: partial interface development, non-core function development, interface adaptation, and joint testing and debugging of the gray box transmission equipment management and control system. It should have entered the interface adaptation and testing and joint debugging stages, and is getting closer to commercial deployment. In addition, this project sets a maximum bid limit, which is RMB 1.9998 million (excluding tax). If the bid price (total price excluding tax) is higher than the maximum limit price, the bid will be suspended. veto.
open decoupled optical network is expected to be deployed on a large scale in operator networks soon.
