DAC cable EFB SC353501J5M24-BL 10GBASE-CR, 5 m

EFB Elektronik DAC cable SC353501J5M24-BL is a pre-terminated Direct Attach Copper (DAC) assembly for short-range 10 Gigabit Ethernet links. The 5 m cable integrates two SFP+ copper modules and a 100 ohm differential data cable to provide a low-latency, energy-efficient 10GBASE-CR connection without external optical transceivers. It is designed for use in data centers and enterprise racks where reliable, cost-effective server-to-switch and switch-to-switch links are required.

Advantages

The EFB DAC cable delivers a plug-and-play SFP+ solution with hot-plug capability and an improved EMC design to minimize electromagnetic interference. As a copper assembly it eliminates the need for separate transceivers, reducing power consumption and total system cost while supporting bi-directional data rates up to 11 GBd. The single 3.3 V power supply requirement and an industrial operating temperature range make the cable suitable for standard networking equipment and cabling infrastructures.

Suitable for

• Short-range 10 Gigabit Ethernet links (10GBASE-CR)
• Server-to-switch and switch-to-switch connections in racks and cabinets
• 10 GFC and serial data transmission environments

Key specifications

• Standard: 10GBASE-CR compliant with IEEE 802.3ae
• Connector type: SFP+ to SFP+ direct attach copper assembly
• Length: 5 meters
• Data rate: supports up to 10 Gbit/s and bidirectional signaling up to 11 GBd
• Cable impedance: 100 ohm differential
• Power: single 3.3 V supply for SFP+ modules
• EMC: enhanced electromagnetic compatibility design
• Operating temperature range: 0 °C to 70 °C

How to use

Install the DAC cable by inserting each SFP+ connector into the corresponding SFP+ port on the network devices until the hot-plug latch engages. Verify link activity and speed on connected devices according to the switch or server interface indicators and management software. No additional transceivers or fiber patch cords are required. For best results, ensure SFP+ ports are configured for 10G operation and that connected equipment supports direct attach copper modules.

Usage recommendations

Use the 5 m EFB DAC cable for short interconnects within the same rack or adjacent racks to maintain signal integrity and avoid unnecessary intermediate patching. Avoid tight bends and minimize mechanical stress on the cable and connectors. Confirm compatibility with your switches and servers against SFF-8431 and 10GBASE-CR support in device documentation before deployment.
