At the Optical Networking
and Communication Conference & Exhibition (OFC), Huawei officially
released its latest 400G optical network solution for commercial use,
which fully supports carriers by offering fast 400G network deployment
in all-service scenarios. Using Huawei's latest oDSP chips, this
solution outperforms the industry benchmarks in transmission
performance. It supports adjustable bandwidths at a tunable
single-wavelength rate ranging from 100 Gbit/s to 400 Gbit/s. This
solution also helps carriers implement rapid 400G network deployment on
live networks, by offering a wide variety of flexible configurations,
catering for all service scenarios on carriers' networks.
From the perspective of the global optical network industry, the
single-wavelength transmission capacity of 400G has approached its
theoretical limit. Depending on the current transmission performance and
distance, high-speed 400G transmission solutions are commercially
applicable only in limited scenarios. However, Huawei's 400G optical
network solution focuses on actual commercial scenarios, optimizing
high-speed transmission signals, including slicing, shaping, and
compression, and balancing between the theoretical limit and commercial
use. It offers the best possible transmission performance under the
limit, thereby satisfying the requirements of various service scenarios,
as follows:
- In access, metro, and DCI scenarios, transmission distances are
short. Although large bandwidths are required, optical fiber resources
are insufficient. This 400G solution uses the simplest configuration to
provide the largest bandwidth and highest spectral efficiency, reducing
transmission costs. In addition, by leveraging industry-leading error
correction coding technology and a signal equalization algorithm, this
solution improves the single-wavelength 400G transmission performance by
50%, meeting requirements of single-span and multi-span models that use
different optical fibers.
- In backbone networks and some complex metro networks, there are
long-haul transmission, a lot of nodes, and high transmission
requirements. Single-wavelength 400G technology does not perform at the
required threshold in real optical networks. To address this problem,
Huawei's solution uses dual-channel 2 x 200G and optimization algorithms
to compress the channel spacing, increases the spectral efficiency by
30% (approaching a single-wavelength rate of 400 Gbit/s), and smoothly
extends the 400G transmission distance to thousands of miles. This helps
carriers rapidly deploy 400G backbone networks by using minimal
bandwidth resources.
In addition, Huawei's 400G solution increases the single-fiber
capacity by 40%, and reduces power consumption by 40%, greatly improving
the network performance and lowering network O&M costs.
Richard Jin, President of Huawei Transmission Network Product Line,
said, "In the 5G era, ultra-high bandwidth will become a basic network
requirement for carriers and high-speed transmission technology is the
key. As 400G is becoming the trend of next-generation optical networks,
Huawei will promote 400G transmission technology to satisfy carriers'
requirements in all-service scenarios. As one of the earliest vendors in
the world to deliver 400G, Huawei continuously seeks to build the most
competitive premium transmission networks and enable global carriers to
achieve commercial success."
The OFC is the most influential international conference &
exhibition in the global optical communications industry. OFC 2018 will
run from March 13 to March 15 in San Diego, California, USA.
