JUNIPER EX-SFP-10GE-DAC-1M Switch Modules & Cards

EX-SFP-10GE-DAC-1M One-Meter DAC

EX-SFP-10GE-DAC-1M is Juniper part 740-030076, a fixed 1-meter passive Twinax assembly with SFP+ ends for 10GbE full-duplex direct attachment. It is not an optical transceiver pair and is not a breakout cable.

Use the shortest correct route

The 1m length suits adjacent devices only when the measured port-to-port path includes vertical offset, bend relief and service loop. Do not route by straight-line distance. If 1m creates connector tension, select EX-SFP-10GE-DAC-3M after checking rack geometry rather than stretching the cable.

Mechanical and electrical limits

Juniper specifies 30 AWG, 1-inch minimum bend radius, 100-ohm characteristic impedance, 3.3V supply and approximately 0.57W consumption per end. Keep the bend radius outside connector strain-relief zones and do not compress Twinax under rack hardware.

Two-ended compatibility

Validate this exact PID against both switch/router interface modules and their Junos releases in Juniper's Hardware Compatibility Tool. SFP+ physical fit or support on one endpoint does not prove the other endpoint is qualified.

Acceptance test

Confirm the 1m label and Juniper part number, inspect both fixed ends and measure the installed path. After insertion verify interface speed, full-duplex state, errors and flaps at both devices; preserve the endpoint models, slots and software releases.

Official evidence: Juniper HCT entry for the exact 1m PID, Juniper passive DAC electrical and mechanical specifications and Juniper 10GBASE-CR ordering reference.
