ZTE 5G Flexhaul Access Product ZXCTN 61V5 Series
Requirements and Challenges of 5G Transport Network
In the 5G era, there are higher requirements for bandwidth,
latency, and number of connections, and the corresponding
challenges are brought to the transport network:
3G, 4G and 5G networks with complex network architecture
Large bandwidth
Strict latency
Ubiquitous connection
Differentiated service SLA
As one of leaders in the 5G era, ZTE innovatively proposed the 5G
Flexhaul transport solution to meet these challenges, aiming to
build a leading 5G transport network for customers.
Introduction to ZXCTN 61V5 Product
ZXCTN 61V5 series products based on ZTE in-house chipsets are
oriented to the transport network access layer. It integrates a
series of innovative technologies such as FlexE/SDN/SR/Network
Slicing and High-precision clock and meets the requirements of
efficient network transport in 5G scenarios such as eMBB, uRLLC and
mMTC. It helps operators and government & enterprise customers to
welcome the arrival of 5G networks in a brand-new way.
ZXCTN 61V5 Series Products
ZXCTN 61V5 series supports 100GE, 50GE, 25GE, 10GE, GE , FE, STM-1
and E1 interfaces with the packet as the core, meeting different
networking requirements of 3G/4G/5G and enterprise & family
customer service. The equipment models include 1RU height ZXCTN
6120H-A/B/C/S, 3RU height ZXCTN 6180H-A/ 6180H, 5RU height ZXCTN
6190H. Besides, ZXCTN 6120H-S is based on the newest generation ZTE
in-house chip empowering transport device higher switching
capacity, large RIB/FIB, SRv6,etc. ZXCTN 6180H-A/6180H/6190H will
also use the new chip and improve equipment capability.
ZXCTN 61V5 series products are suitable for different networks of
customers, which have super lifetime and scalability in terms of
network deployment and technology evolution. Equipment models avoid
model selection problems caused by uncertainty in technology
selection and network evolution, and effectively protects customer
investment.
Product Highlights and Customer Values
Product’s core competitiveness based on in-house chips, providing
long-term stable services for customers
High integration and low power consumption: Based on ZTE's three-in-one (PP, TM, FlexE) chips (integrated
with PP, TM and FlexE), the power consumption is as low as
0.6W/Gbit, meeting the energy saving and emission reduction
requirements and saving customers Opex.

Commercial Chip VS ZTE In-house Chip
Leading performance index: Forwarding latency, P node latency <1.5us and jitter <0.1us
meet the strict latency requirements of uRLLC services. The
industry's fastest protection switching within 1ms protects
customer service security. Time synchronization accuracy has the
error of <1ns, enabling accurate indoor positioning
applications.
High-Performance Access Platform for 5G Access Era
Full-service access: Full-service access interface (25GE/10GE/GE/FE/E1) can be used in
various transport scenarios such as midhaul, backhaul and
enterprise customer access. ZXCTN 61V5 access devices provide a
large number of service interface slots and interface line cards.
One device can flexibly access various services, meeting the
requirement of continuous bandwidth evolution.
Smooth bandwidth upgrade: It supports access-layer 25G/50G/100G flexible bandwidth
networking, intra-board and inter-board aggregation and flexible
bandwidth expansion to meet future ultra-large bandwidth
requirements.

FlexE Binding
Efficient O&M: Support real-time network information collection, fast & accurate
fault location, and intelligent network management and control.
Packet core and Ultra-Low Latency to Build Ultimate Experience
ZXCTN 61V5 solves the problem of uncontrollable IP latency in the
industry and effectively meets low latency requirement of 5G.
Forwarding plane supports two forwarding modes: fast forwarding and
common forwarding. Data forwarding mode can be selected in
accordance with the service type. For time-sensitive services, the
fast forwarding mode is used. Intermediate P node implements a
forwarding latency of less than 3μs through the innovative FlexE
solution and the L1 electrical layer through direct communication,
providing powerful guarantee for new services and new network
architectures and creating excellent 5G service experience for
users.
·
Slicing Channel-XC
Network Slicing to Meet Service Differentiated SLA and Isolation
5G services will present diversified and differentiated features.
Different services have different performance KPIs for transport
networks. The ZXCTN 61V5 introduces the FlexE technology on the
forwarding plane to implement flexible bandwidth allocation and
service isolation, and to meet differentiated requirements in
diversified 5G scenarios through flexible configuration of
resources. The control plane allocates corresponding resources to
different types of services, so that network resources can be used
to the full extent. In this way, the effective network usage can be
improved and differentiated requirements of various services can be
met.
