200G QSFP-DD-DAC

Overview

LANMexx’s QSFP-DD(Double-Density) passive copper cable assemblies double the number of high 25G/lane NRZ and 50G/lane PAM4 when compared

to the existing 100G QSFP cabling systems from 4 to 8 lanes. The QSFP-DD cables enable 200G or 400G in application lengths from 0.5 meter up to and including 2.5 meter in lengths.

 

FEATURES

  1. Configurable & flexible
  2. Backwards plug capability to 100G; seamless transition to future higher aggregate bandwidth
  3. Optimized PCB interface board with auto soldering process
  4. I/O system has 10-12 watt single port dissipative heatcapacity
  5. Assembled with industry leading twin-axial SKEWCLEAR® 8-pair or 16-pair wire
  6. EEPROM in cable assembly
  7. Passive copper length to 2.5 meter
  8. Compatible with existing 100G QSFP based connector ports (with heat sinks and / or light pipes) as well as 200G / 400G ports
  9. RoHS2 compliant
  10. Custom solutions supported
