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.
- OM4 Pro: Broadened Bandwidth, Future Ready
Traditional OM4 fibre provides high bandwidth at 850nm but is
limited in bandwidth for longer wavelengths with a narrow operating
window. By expanding the operating window to 850~870nm, YOFC's
MaxBand® OM4 Pro fibre effectively compensates for signal
degradation resulting from wavelength shifts in optical modules.
This ensures high-quality signal transmission, reduces connectivity
costs for AI data centers, and enables a seamless upgrade for data
center multimode connectivity solutions to 400G, 800G, and higher
speeds.
- OM4 Ultra: Dual Windows, Double Performance
OM4 Ultra fibre extends the operating window to 910nm, achieving
dual operating windows of 850~870nm and 910nm. This innovative
design supports 400Gb/s, 800Gb/s, and 1.6Tb/s single-wavelength and
dual-wavelength transmission systems. Utilizing wavelength division
multiplexing (WDM) technology, it enables high-speed transmission
through fewer fibres, paving the way for potential upgrades to
1.6Tb/s in data centers.
- OM5: All-round High Bandwidth, Pioneer in Multi-wavelength
Transmission
YOFC MaxBand® OM5 fibre provides comprehensive high bandwidth in
the 850~950nm wavelength range. It supports BiDi or SWDM
multi-wavelength transmission systems from 40Gb/s to 1.6Tb/s,
offering a robust fibre foundation for future SWDM transmission
solutions of 1.6Tb/s and above.
- Fully Upgraded and Compatible
With the advancement of data center technology, YOFC's
MMFs have evolved from single-window to wide-window, dual-window,
and multi-window solutions, offering comprehensive fibre options to
customers. These innovative fibre products not only fulfill the
demand for higher-speed networks but also ensure backward
compatibility, facilitating seamless integration with existing
technologies. By providing new fibre optic solutions, YOFC supports
the green and low-carbon development of large-scale data centers in
the age of AI, driving data centers toward a more efficient and
environmentally friendly future.
As a global leader in optical communications, YOFC has been
deeply committed to innovation in MMFs for many years. Their MMF
products are widely used around the world, earning the trust and
praise of numerous customers. With these groundbreaking solutions,
YOFC is dedicated to satisfying the growing demand for data
transmission with enhanced efficiency and reliability. In doing so,
the company is facilitating the growth of data centers in the AI
era and beyond by addressing their need for higher speeds.
