In the era of rapid development of data center and interconnected data, DAC has greatly expanded its market with its outstanding simplicity and price advantage. DAC takes the market by cost, and has the inherent advantages of enhancing signal integrity and excellent flexibility, It has become the first choice of high-speed links (such as 10G, 25G, 40G / 100G and 200G / 400G). This cost-effective interconnection solution is applicable to all large-scale data center networks and enterprise network applications.

Direct Attach Cable introduction:

Direct Attach Cable, it’s abbreviation is DAC. It is a cable assembly purchased with fixed length and fixed joints at both ends. The high-speed cable end uses the same connector as the optical module. However, compared with optical modules, the connector modules on high-speed cables do not have expensive optical lasers and other electronic components, which greatly saves cost and power consumption in short-distance applications. As a low-cost and high-speed data communication solution instead of optical module, it can be widely used in storage area network, data center and high-performance computer connection by connecting switch to router or server.

Advantages DAC:

v Distance: Compared with the active optical cable, the high-speed cable has a shorter transmission distance and is suitable for the short-distance wiring of the data center.

v Material: The inside of the high-speed cable is made of copper core. Copper cable has the function of natural radiator, good heat dissipation effect, energy saving and environmental protection.

v Power consumption: Low power consumption.

v Cost: The price of copper cable is far lower than that of active cable.

200G QSFP28-DD DAC cable:

200GbE QSFP28-DD to 2x100GbE QSFP28 DAC, is used to connect optical fiber network devices and provide high-speed remote connection capability. One end of the 1-meter cable is equipped with a 200GBE QSFP28-DD connector, while the other end is equipped with a 2x100GBE QSFP28 DAC connector

200G QSFP28 to 4×50 SFP28 DAC:

200Gb/s QSFP28 to 4 x 50Gb/s SFP28 copper cable separator cable, used to connect a 50Gb/s server to a TOR switch. In addition, the 200G QSFP-DD supports 8×25Gb/s, cable length is up to 2m.

If your cabling scenario also belongs to short distance transmission, DAC high-speed cable is a good choice for cost consideration.

ETU-Link can provide a cost-effective interconnection solution to help users realize the interconnection between devices more quickly and conveniently.
