Overview

Gives an overview of 800ZR and 800G OpenZR+ optical transceivers. This topic also includes benefits of 800ZR and 800G OpenZR+ optics, and licensing information.

The 800ZR is an Optical Interworking Forum (OIF) standard for transporting 800GbE over long distances through fiber optic cables. The standard defines the solution to transport 800GbE optical signals using a single wavelength.

The primary application of 800ZR optics is to interconnect data centers within a distance of up to 450 km. Data centers require high bandwidth, high speed, and low latency networks. The 800ZR optical module meets these requirements.

800G OpenZR+ is an extension of 800ZR specifications to improve performance and adheres to OpenZR+ MSA standard.

Some characteristics of the 800ZR and 800G OpenZR+ optics are:

  • Configuration of different speeds and negotiation between capacity and reach. For example, 800 Gbps can support nominal reach of 450 km, 400 Gbps up to 500 km, 300 Gbps up to 900 km, and 200 Gbps up to 2000 km.

  • Capacity to carry the signals across long distances through fiber optic cables with periodic optical amplification.

  • Fully C-band tunable and dense wavelength-division multiplexing (DWDM). We support 6.25/12.5/50/75/100 GHz channel spacings.

  • Ability to operate in amplified and unamplified modes.

Benefits of 800ZR and 800G OpenZR+ Optics

  • Cost efficiency: Operators can use 800ZR and 800G OpenZR+ coherent DWDM pluggable optics in IP routers and switches, and directly interconnect to a DWDM line system. The use of these transceivers eliminates the need for external optical transponders, thereby reducing infrastructure maintenance costs and operating expenses for the operators.

  • Reduced carbon footprint, and power and space consumption:

    800ZR and 800G OpenZR+ optics reduce power consumption by up to 50 percent by eliminating the need for external transponders. The elimination of transponders also results in reduced carbon footprint and space requirement.

  • Increased system efficiency:

    800ZR and 800G OpenZR+ optics simplify operations with standard APIs and open data model.

Licensing

You need a license to use the 800ZR and 800G OpenZR+ standards.  For information about the licensing model for  the coherent 800ZR and 800G OpenZR+ optics, see Software Licenses for Juniper Coherent Optics.
