Monoprice 113397 Ironlink SFP+ 10GbE DAC Cable 1M

The Monoprice 113397 Ironlink is a 1-meter SFP+ Direct Attach Copper cable built to replace the Juniper EX-SFP-10GE-DAC-1M at a fraction of the cost. It uses twinax copper conductors terminated with SFP+ connectors on both ends, delivering bidirectional data rates up to 11 GBd. The cable is compliant with SFP+ MSA and 10GFC standards, meaning it meets the same electrical and signaling specifications as name-brand alternatives. For data center operators and network administrators managing Juniper infrastructure, it provides a drop-in solution for top-of-rack switch interconnects, server uplinks, and storage network links.

Because this is a passive copper DAC cable, it introduces less latency than active optical transceiver modules and draws no additional power from the switch's SFP+ port. The trade-off is reach — at 1 meter, it is designed strictly for short-distance connections within the same rack or between side-by-side equipment. The twinax copper construction is inherently stiffer than fiber, so cable management in dense racks may require a bit more planning. That said, for the vast majority of short-run 10GbE scenarios on Juniper hardware, this Monoprice cable delivers identical performance to the OEM part at a meaningfully lower cost.
