400G ZR+ coherent pluggable optics has become a new solution for high-density networks with data
rates from 100G to 400G featuring low power and small space. Let's see how the latest generation of
400G ZR+ optics extends the economic benefits to meet the requirements of network operators,
maximizes fiber utilization, and reduces the cost of data transport.
What is 400G ZR+?
400G ZR+ is a range of coherent pluggable optics solutions with line capacities up to 400Gbps
and reaches well beyond 80km.

400G ZR+ is a leap forward in the application of coherent technology. With higher-order
modulation and DWDM unlocking high bandwidth, the 400G ZR+ module can reduce cost and
complexity for high-level data center interconnects. 400G ZR+ takes implementation challenges
to the next level by adding some elements for high-performance solutions while pushing
component design for low power consumption, pluggability, and modularity.
Application Scenarios
 Extended-reach P2P Packet
400G ZR+ is a straightforward extension of 400G ZR transcoded mappings of Ethernet with a
higher performance FEC to support longer reaches. 400G ZR+ modules are narrowly defined as
supporting a single-carrier 400Gbps optical line rate and transporting 400GbE, 2x 200GbE, or 4x
100GbE client signals for point-to-point reaches (up to around 500km).
 Multi-span Metro OTN
400G ZR+ support OTN, for example, client mapping and multiplexing into FlexO interfaces. In
addition, 400G ZR+ supports the additional requirements of OTN networks, carries both Ethernet
and OTN clients, addresses transport in multi-span ROADM networks, operationalizes OTN regens,
and supports multi-lambda bonding applications. It is required where the demarcation is crucial
to operators and is destined primarily for optical transport platforms.

 Multi-span Metro Packet
400G ZR+ extended reach Ethernet or packet-transcoded solutions that are further optimized for
critical performance metrics such as latency, throughput, and timing. This 400G ZR+ coherent
pluggable with high-performance FEC and sophisticated coding algorithms supports the longest
reach over 1000km multi-span metro packet transport.
 Multi-span Metro Regional OTN
400G ZR+ supports extended reaches such as in multi-hop, metro-regional ROADM networks
with OTN support. It leverages high-performance FEC and PCS, along with tunable optical filters
and amplifiers for maximum reach. 400G ZR+ supports Ethernet and OTN clients, and a rich
feature set of OTN network functions for deployment over fixed and flex-grid line systems.
Conclusion
400G ZR+ provides a comprehensive, open, and flexible coherent solution in a relatively smaller
form factor pluggable module. It addresses hyper-scale data center applications for
high-intensive edge and regional interconnects.
