High Speed DAC Cable 25G SFP28 Direct Attach Cable Transceiver Module

UnitekFiber 25G high-speed cable consists of a passive copper core cable and two SFP28-SFP28 interface optical fiber transceiver modules. The transceiver modules are shaped like optical modules, but there is no laser installed inside. 25G high-speed cables can replace 25G optical modules to achieve short-distance data transmission, and because there is no laser installed, the price is much lower than 25G optical modules. It is a better way for 25G switch short-distance interconnection applications in data centers. It is a common and cost-effective solution.

What is a Direct Attach Copper (DAC) Cable?

A Direct Attach Copper cable or a DAC cable is a Twinax copper cable that connects directly the ports (or line cards) within active equipment, such as switches, routers, servers or data storage devices, in a data network.

Why Choose DAC Cables?

1) Less Power Consumption. 

2) Lower Price. 

3) Simpler Deployment. 

4) Convenient for installers.

Where to Use DAC Cables?

High-speed cables are mainly used for transmission in data center cabinets. Because high-speed cables do not use expensive optical components and optical fibers as components, the transmission distance is short and the price is low. It is very suitable for the connection of servers and switches in the cabinet.

Can the 40G port and the 10G port be connected with a cable?

Yes, the 40G AOC/DAC cable has a QSFP+ to 4*SFP+ branch cable. Using this specification cable, the 40G port and the 10G port can be interconnected.

How many kilometers can the DAC fiber optic cable travel farthest?

The longest transmission distance of copper cable DAC is 7M.

What is the transmission medium of DAC cable?

The transmission medium of DAC is copper cable.
