About the EX-SFP-10GE-DAC-3M
The Juniper EX-SFP-10GE-DAC-3M direct attach copper cable assembly provides high density 10 Gigabit Ethernet connectivity for intra-rack equipment stacking and top-of-rack server interconnects. Constructed with shielded twinaxial copper cabling and factory-terminated SFP+ connector heads, it delivers near zero latency with minimal electrical power consumption.
Compatibility
Compatible with Juniper EX Series switches, QFX Series switches, MX Series edge routers, and enterprise SRX firewalls. It connects switch virtual chassis stacks, high throughput storage arrays, and network adapter cards without requiring separate optical transceivers.
How to identify a genuine unit
Features a heavy duty flexible black twinaxial cable jacket terminated with zinc die-cast SFP+ connector hoods. Both connector ends include an ergonomic pull tab release mechanism and an adhesive label showing Juniper assembly part number 740-030078.
Buying used
Inspect the cable jacket along its full length for sharp kinks, crush marks, or sheath tears. Check the gold-plated connector contacts for wear or contamination, plug both ends into target switch ports, and confirm immediate link synchronization with zero frame check sequence errors.
