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 rang of wire gages-from 28AWG through 30AWG-this 400G copper cable assembly features low insertion loss and low cross talk.
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. w Compatible with IEEE 802.3bj and IEEE 802.3cd
2.    Supports aggregate data rates of 400Gbps(PAM4)
3. w Optimized construction to minimize insertion loss and cross talk
4. w Pull-to-release slide latch design
5. w 28AWG through 30AWG cable
6. w Straight and break out assembly configurations available
7.   Customized cable braid termination limits EMI radiation   
8.   Customizable EEPROM mapping for cable signature
9.   RoHS omplia
