Frequently Asked Questions
Is this cable compatible with non-Juniper QSFP+ equipment?
Yes, while optimized for Juniper QFX-QSFP-DAC-3M compatibility, this cable also complies with MSA (Multi-Source Agreement) industry standards. This ensures broad interoperability with other brands of QSFP+ enabled networking equipment.
What is the maximum distance this 40Gbps passive DAC cable can reliably support?
This 3-meter passive direct-attach copper cable is designed for reliable 40 Gbps connectivity over short distances, typically within a single server rack or between adjacent racks. For longer distances, active optical cables or transceivers would be required.
Does this cable require any special drivers or software for installation?
No, this is a passive direct-attach copper cable with plug-and-play functionality. It does not require any drivers, software, or configuration, simplifying deployment and maintenance.
What are the advantages of using a passive DAC cable over an active optical cable?
Passive DAC cables like this one are generally more cost-effective and consume less power than active optical cables for short-distance connections. They are ideal for in-rack or adjacent-rack connectivity where high bandwidth is needed without the added complexity or cost of optics.
