QSFP-DD Cable Assemblies
DESCRIPTION
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
- Configurable & flexible
- Backwards plug capability to 100G; seamless transition to future higher aggregate bandwidth
- Optimized PCB interface board with auto soldering process
- I/O system has 10-12 watt single port dissipative heat capacity
- Assembled with industry leading twin-axial SKEWCLEAR® 8-pair or 16-pair wire
- EEPROM in cable assembly
- Passive copper length to 2.5 meter
- Compatible with existing 100G QSFP based connector ports (with heat sinks and / or light pipes) as well as 200G / 400G ports
- RoHS2 compliant
- Custom solutions supported
BENEFITS
- 200G or 400G aggregate bandwidth capacity, dual 8-pair or single 16-pair wire supported
- Addresses current and future market desired bandwidth port capability requirements
- Exceeds 25G NRZ and 50G PAM4 performance and SI parameter in standard specification
- Enables use of copper and optical based cabling solutions
- Great SI reliability and physical capabilities (softer and better bending performance than other cables)
- Programmable to customer requirements
- Provides optimized cost, performance, cable bulk & routing solutions
- Meets industry standard signal performance requirements up to lengths of 2.5 meters
- Assured cable pluggability regardless of port bandwidth configuration
- Environmentally friendly
- Custom solutions from adapter cables to loopback cables and beyond
