Frequently Asked Questions
What is a QSFP28 connector and why does it matter for 100GB networking?
QSFP28 (Quad Small Form-factor Pluggable 28) is the industry standard connector for 100 Gbit/s data transmission. It enables four independent 25G channels or a single 100G connection, making it essential for modern data center infrastructure. The QSFP28-100GB-PDAC cable uses this connector to deliver maximum bandwidth in a compact form factor.
How does a passive DAC cable compare to active cables or transceivers?
Passive Direct Attach Cables (DAC) like this AddOn Networks model offer superior advantages: zero power consumption, no heat generation, lower latency, and reduced operational costs compared to active cables or SFP+ transceivers. For short-range connections under 1 meter, passive DAC technology is the preferred choice for 100GB networks.
Is this InfiniBand cable compatible with my data center switches?
Yes, the QSFP28-100GB-PDAC0-5MLZ-J-AO is InfiniBand-certified and compatible with leading data center switches, routers, and network interface cards supporting QSFP28 connectors and 100 Gbit/s speeds. Verify your equipment's QSFP28 port specifications before installation.
What cable length options are available for 100GB connectivity?
AddOn Networks offers this 100GB fibre optic cable in multiple lengths to suit different deployment scenarios. The 0.5-meter version is ideal for high-density server racks and switch-to-switch connections, while longer options are available for extended reach applications.
