Enhancing Data Center Efficiency in the AI Era
WUHAN, China, Sept. 20, 2024 /PRNewswire/ -- Over the past two decades, the rapid growth in the number of Internet users and connected devices has dramatically boosted traffic to global cloud platforms and enterprise data centres. This surge has positioned data centres at the forefront of technological innovation. In recent years, the widespread adoption of AI technology has prompted data centres to evolve toward more efficient computing. As a result, data centre operators worldwide are striving to develop faster, denser, more cost-effective, and more energy-efficient infrastructures.
In the field of short-haul optical communications for data centers, transmission solutions using vertical cavity surface emitting lasers (VCSELs) and multimode fibres (MMFs) are favored for their cost-effectiveness. For 25 Gbaud transmission, OM3 and OM4 fibres have become the dominant choice for link coverage ranging from 70 to 100 meters. However, as data centers transition to higher transmission speeds, the industry is shifting towards the use of 100G/Lane VCSEL transceivers. This shift has introduced new challenges for fibre, the medium for data transmission. Issues such as the central wavelength drift of the light source and bandwidth limitations of traditional OM4 fibre at 850nm or longer wavelengths may lead to a reduction in link transmission distance.
To address these challenges, Yangtze Optical Fibre and Cable Joint Stock Limited Company (hereinafter referred to as "YOFC") has leveraged its deep technical expertise in MMFs to design the high-performance MaxBand® OM4 Pro/Ultra series of MMFs, specifically tailored for 100G/Lane optical transceivers. These new fibre products enhance the transmission efficiency of data centers.
-
MaxBand® OM4 Pro: It offers an effective modal bandwidth of over 4700 MHz*km in the 850nm to 870nm wavelength range. This significantly improves the average bandwidth within this range and effectively addresses the issue of reduced transmission distance caused by central wavelength drift.
-
MaxBand® OM4 Ultra: It provides high bandwidth at wavelengths of 850nm to 870nm and 910nm. This meets the demand for 100G/Lane single-wavelength unidirectional and bidirectional transmission over distances of up to 100 meters, significantly enhancing transmission distance for single-channel 100G and Terabit BiDi links.
YOFC's MaxBand® OM4 Pro/Ultra series of MMFs are fully compatible with existing OM4 and OM5 fibre optic standards, as well as systems based on these standards.
