JUNIPER EX-SFP-10GE-DAC-3M Switch Modules & Cards

EX-SFP-10GE-DAC-3M Three-Meter Link

EX-SFP-10GE-DAC-3M, Juniper part 740-030077, is a 3-meter passive SFP+ Twinax direct-attach cable for a single 10GbE full-duplex link. Both SFP+ ends are integral to the assembly.

Three-meter path planning

This length can span devices separated within a rack or across nearby rack positions when the managed cable route remains within 3m. Measure the actual tray and vertical-manager path, reserve a controlled service loop and avoid excess coils. Compare EX-SFP-10GE-DAC-1M for adjacent ports and EX-SFP-10GE-DAC-5M only when the longer path is necessary.

Cable handling

The official specification lists 30 AWG and a 1-inch minimum bend radius. Support the cable's weight so the fixed SFP+ ends are not loaded sideways. Keep it away from pinch points, sharp rack edges and cable bundles that force a tighter bend.

Platform qualification

Use Juniper HCT to check the exact 3m PID on each endpoint, interface module and software release. The same part number can appear under several Juniper product families, but support remains platform- and release-specific.

Receiving and link validation

Match part 740-030077 and the 3m marking, inspect latch and strain relief at both ends, then record the connected devices and slots. Verify negotiated 10GbE full-duplex operation, counters and stability after the cable is placed in its final route.
