SFP+ to SFP+ 10G Direct Attach Copper Cables
SFP+ 10G DAC CABLES
10G DAC Twinax Cables up to 15m
Connect SFP+ to SFP+ ports over short distances
SFP+ 10G Direct Attach Copper (DAC) cables (sometimes referred to as a Twinax cable) are a low-cost 10G Ethernet solution for connecting SFP+ ports over short distances. They are perfectly suited for connections in racks or to adjacent cabinets between switch, router, and server ports.
DAC cables are pre-connected with SFP+ interfaces. These cables are supplied in fixed lengths of 0.5m, 1m, 2m, 3m, 4m, 5m, and 7m for Passive DAC cables, and 10m, 12m, and 15m for Active DAC cables, but each can also be made by our team to a custom length.
Passive or active?
SFP+ DAC cables are available in two versions, passive and active. Passive DAC cables are typically used over short distances, up to 7m, where no additional electrical components for longer signal conditioning is used.
However, Active DAC cables do use electronics in the modules so they are able to transmit over a slightly longer distance, typically up to 15m. Active cables can be used for shorter distance transmission that passive DAC cables would normally be used for, if required.
10GBASE-CR transmission
Supporting 10G transmission, this cable is also able to offer backward compatibility to 1G data rates that use the SFP+/SFP interface. Passive SFP+ 10G DAC cables have a low power consumption per port, typically less than <0.1W.
Compliance
All SFP+ 10G DAC cables are compliant with MSA (Multi-Source Agreement) SFF-8432, SFF-8472.
Vendor/OEM compatibility
These SFP+ 10G DAC cables can be programmed to be compatible with all major switch and server brands, such as Arista, Cisco, Dell, HP, and Juniper (see full list of options above). Complete Connect DAC cables have a 5-year warranty and a 90-day guarantee to test compatibility.
We can offer a cross compatibility service allowing multiple vendors to be connected from the same DAC direct connect cable. For example, end A could be programmed to be compatible with Arista while end B could be programmed to work with Mellanox.
