Product Positioning

XS-OT-400G-QSFP112-LR4 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 QSFP112 form factor.
  • Supports LR4 link profiles up to 10km over singlemode media.
  • Uses CWDM 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-QSFP112-LR4 when building or refreshing leaf, spine, access, aggregation, storage, or AI network links that require 400G optics in the QSFP112 package. The SKU keeps speed, form factor, and reach visible so operations teams can match modules to switch ports and cabling plans quickly.
