Development Trend of Enterprise Transport Networks
In traffic flood, AI/ machine learning is
used to implement intelligent on-
demand, improving O&M efficiency.
Intelligent O&M
HD video, data center disaster
recovery, massive terminal access,
large network bandwidth requirements
Bandwidth Increase
Connectivity of Everything Promotes Rapid
Growth of Network Scale and Traffic,
Simplifying Networks, and Adapting to
Rapid Changes
Simplified network
Intelligent bandwidth on-demand
and fast service provisioning
With the rapid growth of services, the
network is simplified and resources
are configured on demand.
The 700,000 HD camera is
deployed in Shenzhen Safe City to
build a core backbone network.

Challenges Faced by Enterprise Transport Networks
Enterprise customers are in urgent need of intelligent, simplified, and efficient new transport networks to
facilitate rapid digital transformation.
• Diversified services, complex network
structure, unable to quickly adapt to
new service requirements
• Chimney-style network stacking, high
TCO
• There are many types of devices, and
network expansion and upgrade are
difficult.
• The network scale increases
rapidly, but the manual O&M
efficiency is low and the cost is
high.
• Manual review, planning, and
configuration service
provisioning for 30 days
• Fault locating relies heavily on
manual operations, and
troubleshooting takes several
hours.
• CCTV provides Yan Jun
challenges for traditional SDH
network bandwidth.
• Data center disaster recovery
(DR): 100 Gbit/s bandwidth
• Bandwidth operation, lighting
up Dark fiber
Manual O&M
Rapid growth of bandwidth
requirements
Complex network redundancy SDH Network Evolution
• Traditional SDH 10GE rings
cannot meet new service
requirements, such as 100GE,
FC3200.
• Many SDH devices are close to
the end of life, resulting in high
maintenance costs.

Big data + intelligent computing
• Extensive data: decades of optical
network experience data and fiber
parameters on the live network
• Intelligent algorithm: Introduce key fiber
performance events, optimize algorithms,
and profile fibers.
Efficient data collection
• Real-time: Built-in OTDR detection, online
and real-time collection of fiber data on the
live network
• Efficient: Automatic orchestration of detection
sequences to implement concurrent collection
of network-wide optical fibers
AI fiber profile comparison
• AI profile: fiber AI profile for the working
and protection paths
• Accurate comparison: Accurately
compares the fiber profiles of the
working and protection trails for
accurate judgment.

• Platforms and line boards on the legacy network (old OSN
1800 V) and core nodes (9800 XBAR) do not need to be
replaced. Only gray interconnection and extended cross-
connect boards need to be expanded.
• Ethernet services can be accessed through EoO+ at any
node.
• E1 services can be accessed through 2M interface boards.
• Aggregation/core nodes (E6616 and E9624) support OSU
cross-connections.
