FAQ
What devices is this QSFP+ Direct Attach Cable compatible with?
This cable is 100% compatible with Juniper QFX-QSFP-DAC-1M switches and routers. It also works with MSA-compliant switches from other manufacturers including Ubiquiti, D-Link, Netgear, Supermicro, and TP-Link that accept uncoded QSFP+ modules. The cable supports various network devices such as switches, routers, servers, and transceivers with QSFP+ ports.
What is the difference between passive and active direct attach cables?
This is a passive direct attach cable, meaning it contains no signal conditioning electronics and requires no external power. Passive cables like this one are typically used for shorter distances (up to 5 meters for 40GbE) and offer lower power consumption, reduced heat generation, and cost savings compared to active cables that include signal amplification electronics for longer reach applications.
Can this cable be hot-swapped during operation?
Yes, this QSFP+ Direct Attach Cable features hot-swappable connectors that allow installation and removal without powering down your network equipment. This capability enables maintenance and reconfiguration without disrupting network operations, making it ideal for mission-critical environments where uptime is essential.
What is the maximum data transfer rate supported by this cable?
This direct attach cable supports a full 40 Gbit/s (40GbE) data transfer rate. It utilizes twinaxial copper construction with 100 Ohm impedance to maintain signal integrity at this high speed over its 1-meter length, making it suitable for bandwidth-intensive applications such as data center interconnects, server clustering, and high-performance networking.
