DAC cable EFB Elektronik SC353501J2M30-BL

The EFB Elektronik SC353501J2M30-BL is a 2-meter DAC (Direct Attach Copper) cable composed of two SFP+ modules connected by a 100 Ohm data cable. Designed for short-reach high-speed links, this DAC cable supports 10 Gigabit Ethernet and 8.5 Gigabit Fibre Channel applications and is suitable for InfiniBand and fibre optic equipment that accept SFP+ copper transceivers. The black jacket provides a discrete, professional appearance while maintaining robust signal integrity for data center and networking environments.

Advantages

This DAC cable offers a cost-effective solution for short-distance high-bandwidth connections, combining integrated SFP+ modules with a pre-terminated copper cable to simplify installation. Its 2 m length balances reach and reduced latency for rack-to-rack or within-rack connections, and the 100 Ohm impedance ensures compatibility with standard SFP+ ports. The product is built for reliable performance in dense networking setups with lower power consumption compared to active optical alternatives.

Suitable for

• 10 Gigabit Ethernet short-reach links
• 8.5 Gigabit Fibre Channel connections
• InfiniBand and server/storage interconnects
• Data centre rack-to-rack or within-rack cabling

How to use

Install the DAC cable by inserting each SFP+ module into the corresponding SFP+ port on the network devices until the latch clicks into place. Route the cable to avoid sharp bends and keep it clear of high-power or high-heat sources. No additional transceivers or fiber patch cords are required. Verify link status on connected devices and, if needed, check device compatibility lists for vendor-specific restrictions.

Recommendations

For reliable operation, use this 2 m DAC cable for short-reach connections within the same rack or adjacent racks. Avoid exceeding the recommended bend radius, and consult your switch or server vendor’s compatibility list to ensure firmware or hardware support for third-party SFP+ DAC modules.
