ICC News (compilation: Nina) based on Dell'Oro According to the Group's latest forecast report, the market revenue of optical DWDM equipment is expected to reach $18 billion by 2028. The entry of coherent DSPs capable of delivering wavelength speeds in excess of 1Tbps is expected to drive the market growth over the next five years.

Jimmy, Vice President of Dell'Oro Group "We expect the development of a new generation of coherent DSPs capable of terabit speeds to accelerate over the next five years," Yu said. By 2028, more than half of the DWDM market revenue is expected to come from 1.2Tbps and 1.6Tbps line cards. These new line cards will bring 400Gbps wavelengths to ultra-long-haul applications spanning thousands of kilometers and 800Gbps elsewhere. ”

Other highlights from the Optical Transmission Five-Year Forecast Report released in January 2024:

1. The demand for DWDM long-distance equipment is expected to grow faster than metro equipment and contribute a higher share of market revenue over the next five years.

2. Coherent wavelength shipments at terabits per second will grow at a compound annual growth rate of 200% over the next five years.

3. By 2028, the baud rate will exceed 100 There will be more than 40% of new devices at GHz. A high baud rate will reduce the total number of wavelengths per fiber, but a larger channel will provide better performance and longer coverage while reducing costs.
