What is 100ZR?
Addressing traffic growth at the optical edge
400ZR pluggable coherent optics are disrupting optical networks. They offer advantages such as low cost, compact form factor and minimal power consumption, and can be plugged directly into headend devices such as routers or switches. Initially driven by hyperscale data center operators for cost-efficient 400GbE point-to-point data center interconnects, network operators and service providers are now interested in using a similar approach to upgrade their edge aggregation networks to 100Gbit/s. This has motivated the development of 100ZR coherent pluggable transceivers with a small form factor and impressive power efficiency.
Versatile, interoperable 100ZR transceivers
Addressing demand for 100Gbit/s speeds at the optical edge, 100ZR transceivers with an open and standardized interface offer affordability, operational simplicity and optimized performance.
Adtran Coherent 100ZR’s cost-efficiency and operational simplicity provide a compelling solution for operators striving to meet the increasing demand for 100Gbit/s transport at the optical edge.
Leveraging coherent technology
Coherent detection is more robust against fiber optic transmission impairments than direct detection and simplifies optical line requirements.
Purpose-built innovation for the optical edge
100ZR coherent pluggable transceivers based on 400ZR technology are not efficient for 100Gbit/s transport at the optical edge as they cannot meet critical cost, size and power demands. With a purpose-built DSP co-developed by ADVA (now part of Adtran) and II-VI (now Coherent Corp.), Adtran’s Coherent 100ZR is the first 100ZR coherent pluggable transceiver with a QSFP28 form factor that is compliant with stringent QSFP28 power specifications (5W). It enables any device with a QSFP28 port to transport 100GbE or OTU4 services over distances stretching up to 120km without and 300km with optical amplification. Moreover, it can be deployed in outdoor locations outside the central office, such as street cabinets.
QSFP28 form factor and power
Adtran’s Coherent 100ZR is the first 100ZR coherent pluggable transceiver with a QSFP28 form factor and power envelope (5W).
Boosting optical edge capacity
Our 100ZR coherent pluggable transceiver is the ideal solution for edge aggregation networks looking to upgrade to 100Gbit/s. One of its key advantages is its compatibility with any open line system, including 10Gbit/s-based line systems. This means operators can seamlessly upgrade their existing 10Gbit/s-based infrastructure without extensive alterations. The use of coherent detection eliminates the need for dispersion compensation modules, simplifying optical line system requirements and providing a longer transmission reach than direct detect-based solutions. What’s more, a fully C-Band tunable interface with automatic wavelength tuning simplifies operational processes and minimizes inventory. Adtran Coherent 100ZR’s cost-efficiency and operational simplicity provide a compelling solution for operators striving to meet the increasing demand for 100Gbit/s transport at the optical edge.
