Network Cable Juniper JNP-SFP-25G-DAC-1M SFP 25GBase 1m Black

The Juniper JNP-SFP-25G-DAC-1M SFP 25GBase 1m Black is a direct attach copper cable engineered for 25 Gigabit Ethernet links in rack and data center environments. At 1 meter length it connects SFP+ style ports directly, providing a low-latency physical link for switches, routers, and servers where short-reach, high-bandwidth cabling is required. The cable uses SFP form-factor connectors and complies with 25GBase electrical signaling to support high-throughput, point-to-point connections while minimizing power consumption and heat generation.

Advantages

This direct attach cable offers predictable electrical performance for short-distance interconnects, with low insertion loss and minimal latency compared to optical transceivers plus fiber. Its fixed 1 m length simplifies cable management in dense racks and reduces clutter. The durable outer jacket and robust connector housings ensure mechanical stability and repeated mating reliability. The black color provides a neutral appearance that integrates with typical data center cabling schemes.

Suitable for

• Short-reach connections between switches and top-of-rack servers
• High-density patching in data center racks and aggregation cabinets
• Direct connections for storage systems and network appliances that support SFP 25G interfaces

Key specifications

• Data rate: 25 Gigabit Ethernet (25GBase)
• Connector type: SFP form-factor on both ends
• Length: 1 meter
• Media: twinaxial copper direct attach cable
• Color: black
• Typical use: short-reach, point-to-point links in rack environments

How to use

Ensure both devices support 25G SFP direct attach copper connections before installation. Power down or follow hot-swap procedures recommended by the equipment vendor if required. Align each SFP connector with the device port and insert until the latch engages; verify link status through device LEDs or management interfaces. Avoid sharp bends or excessive pulling on the cable; maintain recommended bend radius and secure excess cable to prevent strain on connectors.

Usage recommendations

Use this 1 m direct attach cable for short, fixed interconnects where low latency and predictable electrical behavior are important. Keep the cable away from sources of electromagnetic interference and avoid routing across heat sources. For longer distances or mixed-vendor optical links, consider appropriate fiber-optic transceivers and patching instead.
