HOSECOM, as an outstanding enterprise in the field of optical communications, is committed to the development of optical fiber communications. We have noticed that a laboratory recently released a major innovation at the China Optics Valley·Optoelectronic Information Industry Innovation and Development Conference: based on hollow-core optical fiber. Ultra-large capacity real-time transmission system. This breakthrough experiment not only once again proved the innovative potential of large-capacity optical fiber transmission systems, but also provided a theoretical basis and practical basis for future optical network communication systems with high speed, ultra-large capacity, ultra-long distance and ultra-low latency.
Here are the key results of this innovative experiment:
The laboratory successfully realized real-time transmission of 19.65Thz ultra-wideband S+C+L band, covering a large wavelength range of 1465nm-1627nm. Under single-fiber bidirectional transmission with the same wavelength, the maximum transmission capacity exceeds 270Tbit/s, and the single-wavelength rate is as high as 1.2Tbit/s. This achievement not only improves the transmission bandwidth, but also provides strong support for the performance of optical communication systems.
The wide-spectrum wavelength conversion equipment independently developed by the laboratory realizes bidirectional conversion of C-band optical signals and S-band. This technology allows the use of C-band transceiver equipment for real-time transmission in the S-band. It has the advantages of being transparent to the modulation format and rate, and having a femtosecond response time. When the S-band device industry chain is not yet mature, this technology provides a solution for S-band real-time transmission.
During single-fiber bidirectional transmission in traditional solid-core optical fibers, signals of the same wavelength will be affected by back-rayleigh scattering of opposite signals and degrade. However, with the use of anti-resonant hollow-core optical fiber, the light-guiding medium is replaced by air instead of traditional quartz glass, making bidirectional transmission of single fiber with the same wavelength possible. Based on hollow-core optical fiber, large-capacity single-fiber bidirectional transmission with a total transmission capacity of more than 270T is achieved.
This innovative breakthrough will further promote the development of optical fiber communications and provide faster and more reliable connections for new business applications such as the digital economy, AI, and cloud computing. HOSECOM will continue to be committed to technological innovation and work with partners to promote the construction of optical fiber network communications.
