Tianyuan Labs and SixthFourth Technology jointly announce the launch of the industry's first 170GHz broadband optical device frequency response meter - GOCA-170, an innovation that will bring revolutionary advances in the field of optical communications.The release of the GOCA-170 not only fills the domestic and international gaps in the field of ultra-high-speed optical communications testing, but also meets the requirements of AI large models, large data centers, 5G/6G communication systems, and new defense equipment and other optical devices. , it also meets the key needs of strategic military and civilian information systems such as AI big models, large data centers, 5G/6G communication systems and new national defense equipment.

Technical breakthrough:

The core technology of GOCA-170 is completely independent and controllable, and has made breakthroughs in the following three key technologies:

1. microwave photonic frequency doubling technology: it realizes the multiplication of measurement bandwidth and breaks through the 170GHz mark.

2. optical carrier modulation frequency response measurement technology: accurate characterization of the multi-dimensional frequency response of new high-speed coherent optical devices.

3. Magnitude-phase manipulated phase modulation measurement technique: improves the accuracy and stability of frequency response measurement of electro-optical phase modulators.

Performance Validation:

The performance of GOCA-170 in the 10MHz-170GHz frequency band has been comparatively verified by standard optical outlier methods, showing extremely high consistency and ensuring the accuracy of the measurement results.

Industrial Impact:

As a key equipment for the research and development of high-speed optical communication systems, GOCA-170 will promote the continuous progress and upgrading of single-wave 400G, single-module 3.2T and above optical communication technologies, and provide a strong impetus for the upgrading of the optoelectronic industry.

Brief introduction of the cooperating parties:

Tianyuan Laboratory: a state-level key laboratory built on the basis of Nanjing University of Aeronautics and Astronautics, dedicated to research in the field of microwave photonics technology, with 180 full-time scientific researchers, of which 48.3% are talents above the provincial and ministerial level.

Sixth and Fourth Technology: a high-tech enterprise specializing in the research and development of optoelectronic measurement instruments, with products that have broken through foreign monopolies and filled the gaps in the country, providing high-end optical device measurement solutions for a number of strategic areas.
