Product Positioning
XS-OT-400G-QSFP-DD-ZR is an xSONiC optical transceiver for 400G network links that need predictable compatibility across data center, enterprise, and AI fabric environments. It is positioned for teams standardizing optics by speed, form factor, reach, and media type while keeping sourcing and deployment records easy to trace.
Core Capabilities
- Provides 400G connectivity in a QSFP-DD form factor.
- Supports ZR link profiles up to 120km over singlemode media.
- Uses C-band wavelength characteristics for the target optical profile.
- Terminates through LC Duplex interfaces for compatible cabling designs.
- Fits xSONiC switch deployments where optics need to map cleanly to port speed and link distance.
Typical Deployment Scenarios
Use XS-OT-400G-QSFP-DD-ZR when building or refreshing leaf, spine, access, aggregation, storage, or AI network links that require 400G optics in the QSFP-DD package. The SKU keeps speed, form factor, and reach visible so operations teams can match modules to switch ports and cabling plans quickly.
