Frequently Asked Questions
What is a QSFP28 direct attach cable used for?
A QSFP28 direct attach cable connects high-speed network equipment like switches and servers without requiring separate transceiver modules. The passive copper design makes it cost-effective for short-distance 100 Gigabit interconnects within data centers and enterprise networks.
Is this cable compatible with Arista Networks switches?
Yes, the AddOn QSFP28-100GB-PDAC3MLZ-AR is specifically designed as an Arista Networks compatible cable. It has been verified for interoperability with Arista switching platforms and meets all performance specifications for seamless integration.
What does LSZH mean and why does it matter?
LSZH (Low Smoke Zero Halogen) refers to the cable jacket material that produces minimal smoke and no toxic halogen gases if exposed to fire. This makes LSZH cables safer for enclosed spaces like data center racks and is often required by building codes and compliance standards.
Can I use this passive copper cable for longer distances?
The AddOn QSFP28 passive copper cable is rated for a maximum reach of 3 meters. For longer distances, active optical cables (AOCs) or amplified solutions are recommended to maintain signal integrity and performance.
