Typical Applications

Product Highlights

    1.Massive 400G Throughput for Next-Gen Bandwidth Capacity
  • Leverages an advanced 8x 50G PAM4 modulation architecture to deliver up to 400Gbps of aggregate throughput on a single interface. It effectively quadruples the bandwidth capacity of standard 100G links to tackle heavy data traffic seamlessly.

    2.10km Long-Reach Capability for Metro and Core Backbones

  • Driven by high-performance LAN-WDM lasers, this transceiver is optimized for reliable data transport up to 10 km over standard Single-Mode Fiber (SMF). It serves as the ideal solution for Data Center Interconnects (DCI) and enterprise backbone rings.

    3.Backward-Compatible QSFP-DD Footprint for Seamless Aggregation

  • The industry-standard QSFP-DD form factor maximizes front-panel port density while offering excellent backward compatibility with existing QSFP packages (e.g., QSFP28). This allows operators to scale their networks efficiently without sacrificing legacy investments.

    4.Precision LAN-WDM Optical Design & Native DOM Support

  • Multiplexes 8 precision-spaced LAN-WDM wavelengths on a single fiber pair to minimize optical dispersion over 10km long hauls. Backed by full Cisco Part Number (10-3441-01) integration, it features complete Digital Optical Monitoring (DOM) for real-time proactive tracking of Tx/Rx power and temperature.
