Amphenol's QSFP28/56G Loopback Modules are part of our comprehensive QSFP28/56G product family which includes copper cables, active optical cables, and connectors. These QSFP28/56G loopbacks are offered as passive electrical with multiple attenuation and thermal consumption levels. QSFP28/56G loopbacks are designed to support data speeds up to 100G/200G (4 lanes at 25G/50G).

Features & Benefits
  • SFF-8665 / SFF-8636, and QSFP28 MSA compliant module
  • Supports all industry standard ports
  • The module is composed of a high-frequency Printed Circuit Board (PCB) designed with controlled impedance traces to loopback each of the 4 high speed lanes
  • Low cost tool to allow individual port testing without using a cable assembly which tests 2 ports and is harder to handle
  • Enables electrical system de-bug and validation testing
  • Available with or without thermal loading and with or without attenuation settings
  • Cost-effective testing devices for host hardware ports
  • EEPROM per QSFP28 MSA; customization is available
  • Enables system communication over I2C bus
  • Supports custom solutions
  • Meets customer specific applications and designs
  • Part of Amphenol's overall QSFP28/56G based product offerings
  • Comprehensive QSFP+ I/O system that includes passive copper, active optical cabling & connector solutions
