What is a 25G DAC?
25G DAC is a DAC whose actual transmission rate can reach 25G, and 25G DAC can transmit at a distance of less than 7 meters. 25G DACs are generally used in 25G short-distance transmission networks, plugged into 25G optical ports, and connected to another 25G optical port in the same rack or adjacent racks.
Now the price of sfp28 dac cableis reasonable, if you have needs, please contact us.
