UnitekFiber Direct-connected cables are an ideal short-distance connection solution to replace optical modules. They are divided into two categories: high-speed cables (DAC) and active optical cables (AOC). QSFP direct-attached optical cable meets all IBTA, QSFP MSA and SFF-8436, Infiniband QDR specifications, and provides a cost-effective solution for short-distance high-speed data transmission in data centers.

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.
1) Less Power Consumption.
2) Lower Price.
3) Simpler Deployment.
4) Convenient for installers.
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.
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.
The longest transmission distance of copper cable DAC is 7M.
The transmission medium of DAC is copper cable.
I have received the order, and your shipping time is out of expected. And the FTTH drop cable are functioning just as expected. we have always been satisfied with our equipment from you.
