Multiple Choice

The 100G QSFP28 FR1 is a single-wavelength 100-Gigabit Ethernet transceiver for links up to 2 km. It utilizes 100G PAM4 optics around 1310 nm on a duplex LC interface and presents a CAUI-4 (4×25.78 G NRZ) electrical host with an integrated gearbox—ideal for spine/leaf fabrics, campus DCI, and metro access where simple LC cabling and longer reach are required.

  • Standards & Management

    • Optical: 100GBASE-FR1 (IEEE 802.3cu)

    • Electrical host: CAUI-4 with in-module gearbox to 1×100G PAM4

    • Module management: SFF-8636 (DOM/diagnostics, alarms)

  • Optics & Reach

    • Wavelength: ~1310 nm single lambda (PAM4)

    • Connector/Fiber: LC duplex, OS2 SMF

    • Reach: up to 2 km

  • Performance & Power

    • Line rate: 100 GbE (1×100G PAM4 on the optical lane)

    • Typical power: ≤ 4.5 W (platform-dependent)

    • Low BER with host FEC; PRBS/loopback support (host-dependent)

  • Reliability & Environment

    • Case temperature: 0 ~ +70 °C (commercial); industrial on request

    • Laser safety: Class 1 (IEC 60825-1)

    • RoHS/REACH compliant

  • Use Cases

    • 100G spine–leaf interconnects needing 2 km reach

    • Campus/metro DCI over duplex SMF

    • Aggregation uplinks where LC-duplex simplifies deployment
