China 200G 400G DCI supplier

100G CFP to QSFP28 Adaptor Module with FEC

Features

  • CAUI -10 Electrical Interface:10 Lanes @10Gbit/s for CFP port
  • CAUI -4 Electrical Interface:4 Lanes @25.78Gbit/s for QSFP28 port
  • Hot Pluggable
  • Low latency FEC
  • MDIO, I2C Support
  • Compliant to CFP MSA
  • Case operating temperature: 0 to 70 °C
  • The RQ-CFP-QSFP28-F Adaptor Module converts a 100 Gigabit CFP port into a 100 Gigabit QSFP28 port. With the Adaptor Module, customers have the flexibility to use the 100 Gigabit CFP interface port of a switch with CFP modules or QSFP28 modules. For 100G Ethernet, reference clock can switch 161.133mhz or 644.531mhz; For OUT 4, reference clock can switch 174.703mhz or 698.812mhz; Users can control whether FEC function is enabled or not through register configuration.
