Huawei eyes up optical network opportunities
Hot on the heels of delivering its 2020 strategy for 5G
technology, and aiming to upgrade its intelligent network strategy to enable
premium experience in the 5G era, Huawei has launched what it says is the
world’s first Liquid optical transport network (OTN) system.

Liquid OTN is designed to enable the convergence of
transport and access networks with its end-to-end optical connectivity
constructed to ensure ultra-high bandwidth and ultra-low latency. This is said
to help operators and enterprises build networks with guaranteed good
experience to achieve business success in home and enterprise scenarios.
Explaining the proposition at the Huawei products and
solutions launch in London, Kevin Huang, vice-president and chief marketing
officer of Huawei’s transmission and access network product line, said:
“Network innovation is shifting from bandwidth-driven to experience-driven.
Therefore, our innovation will focus on connectivity, bandwidth and latency to
bring unparalleled experience for users and enable the business success of
operators, enterprises, and industries.
“Huawei aims to build ubiquitous optical connections and lay
a solid foundation to provide an outstanding experience for end users,” he
added.
Said to be the industry’s first small-granularity OTN
system, Liquid OTN adopts Huawei OptiXtrans products and has three key
capabilities, which are ubiquitous all-optical connectivity, hitless bandwidth
adjustment, and ultra-low transport latency.
Huawei sees Liquid OTN as acting as an engine for the
optical transport networks from physical transport networks to service
transmission networks, supporting operators, enterprises and industries in
building experience-centric transmission networks.
Furthermore, Huawei attributed it with having the potential
to promote the prosperity of the global optical network industry and achieve
the balanced development of industry and business innovation.
Liquid OTN introduces OSUflex containers to support flexible
bandwidth definition. Furthermore, network hard slices can achieve a fine
granularity of 2 Mbit/s, improving the number of supported connections “by 500
times”. The system also supports hitless bandwidth adjustment from 2 Mbit/s to
100 Gbit/s, ensuring zero service interruption and full use of network
resources.
It is also said to flatten significantly the network
transport layers, providing differentiated latency levels and reducing per-site
latency by 70% to reach the microsecond level, adapting to different
delay-sensitive scenarios.
Also part of the new offers, Huawei has launched AirPON,
which is said to be the industry’s first optical access system for fixed mobile
convergence. The AirPON system comprises the blade OLT, the Digital QuickODN
(DQ ODN) in Huawei’s OptiXaccess portfolios, and Huawei’s OptiXstar home
terminals. It is designed to help mobile operators quickly develop high-quality
gigabit fibre broadband services.
The system is said to have a number of advantages such as
“0” site acquisition, using existing mobile stations to shorten the fibre
access distance from 5km to less than 1km, significantly improving network
construction efficiency and reducing the capital expenditure (capex) by 27%.
The AirPON system also supports end-to-end optical
distribution network (ODN) visualisation to achieve accurate resource
management and fault locating, as well as fast service provisioning, reducing
the ODN sunk cost by 20%. DQ ODN-based end-to-end pre-connections improve the
construction efficiency by 70%.
The third part of the optical offer is Huawei eAI ONT, which
Huawei claims is the industry’s first optical network terminal (ONT) product
with embedded artificial intelligence (AI) that can intelligently identify the
service types.
Wi-Fi 6 slicing and intelligent power adjustment
technologies are said to be able to halve the latency of some services,
increasing the average revenue per user (ARPU) of home users. In addition, the
product adopts the APM intelligent sleep mechanism, which Huawei says reduces
the overall power consumption by 20% compared with other suppliers.
