Overview

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

800G-ZR 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 800G-ZR 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 800G-ZR optical module meets these requirements.

Some characteristics of the 800G-ZR 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 800G-ZR Optics

  • Cost efficiency: Operators can use 800G-ZR 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:

    800G-ZR 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:

    800G-ZR optics use standard APIs and an open data model (DM) to simplify operations.

Licensing

You need a license to use the 800G-ZR standards.  For information about the licensing model for  the coherent 800G-ZR optics, see Software Licenses for Juniper Coherent Optics. For additional information about License management, see Licensing Guide. You can also contact your Juniper Account Team or Juniper Partner.
