400G QSFP-DD Passive Direct Attach Copper Twinax Cable 1.5m

 

General Description

QSFP-DD passive copper cable assembly feature eight differential copper pairs, providing four data transmission channels at speeds up to 56Gbps(PAM4) per channel, and meets 400G Ethernet and InfiniBand Enhanced Data Rate(EDR) requirements. Available in a broad range of wire gages-from 28AWG through 30AWG-this 400G copper cable assembly features low insertion loss and low crosstalk.
QSFP-DD uses PAM4 signals for transmission, which doubles the rate. However, there are more stringent requirements for cable insertion loss. For detailed requirements, please see High Speed Characteristics.

Features and Benefits

  1. Compatible with IEEE 802.3bj and IEEE 802.3cd
  2. Supports aggregate data rates of 400Gbps(PAM4)
  3. Optimized construction to minimize insertion loss and crosstalk
  4. Pull-to-release slide latch design
  5. Straight and break out assembly configurations available
  6. Customized cable braid termination limits EMI radiation   
  7. Customizable EEPROM mapping for cable signature
  8. 28AWG and 30AWG cable
  9. 3.3V Power supply
  10. Temperature Range: 0~ 70 °C
  11. RoHS Compliant
