Frequently Asked Questions
What is a 100GBASE-CR4 QSFP28 to SFP28 passive cable used for?
This passive copper cable is used to split a 100GbE QSFP28 connection into four separate 25GbE SFP28 connections. It's ideal for data center environments where you need to distribute high-speed bandwidth across multiple ports without the cost and complexity of active transceivers.
Why choose a passive copper cable over active solutions?
Passive copper cables eliminate power consumption, reduce latency, and offer significant cost savings compared to active transceivers. For short-reach data center interconnects, 100GBASE-CR4 passive solutions provide reliable performance while minimizing operational expenses.
What is the maximum distance for this QSFP28 to SFP28 splitter?
This direct attach copper splitter is optimized for short-reach applications up to 30 meters, making it perfect for in-rack and adjacent-rack connections in data centers. For longer distances, optical solutions are recommended.
Is the Axiom 100GBASE-CR4 cable compatible with my network equipment?
The QSFP28 to 4x25GbE SFP28 passive cable is compatible with any equipment supporting 100GBASE-CR4 QSFP28 ports and 25GbE SFP28 ports. Verify your switch or network interface card specifications to ensure compatibility before purchase.
