Explore the applications and features of 10G SFP+ DWDM colored optical modules
The DAC high-speed cable is a fixed-length cable assembly with fixed connectors at both ends. The connectors of dac cable have no optical lasers and other components. So direct attach cable can only transmit electrical signals, but not optical signals. dac direct attach cable is a low-cost and high-efficiency Communication solutions which can greatly save cost and power consumption in short-distance applications.
Besides direct attach cable, Gearlink professional optical transceiver manufacturer also provide a variety of transceivers such as 400g transceiver, 40g qsfp+ transceiver, active optical cables, module sfp 10g, sfp transceiver, etc.

GearLink's DAC can be divided into 10G DAC, 25G DAC, 40G DAC, and 100g dac cable according to the transmission rate.
DAC means direct cable or direct-connected copper cable, a cable assembly with fixed connectors at both ends, the module and copper cable cannot be separated.
The function of the optical module is photoelectric conversion, but the module connected on DAC has no optical devices and electronic components, so it can only transmit electrical signals.
The full name of DAC high-speed cable is Direct Attach Cable, and we generally call it high-speed cable. Fixed-length cable assemblies with fixed connectors at both ends, non-replaceable connectors, modular connectors and copper cables that cannot be separated. DAC is generally used for short-distance transmission and only transmits electrical signals.
The transmission distance of DAC is very short, generally only up to 7 meters. The application scenario of DAC is generally to connect and transmit in the same rack or adjacent racks in a short distance. In the face of different network requirements, DACs with different rates can also be selected. DAC rates are 10G, 25G, 40G, 100G, 200G, 400G, etc. DACs are mostly used in data centers.
DACs are generally used in short-distance transmission networks, plugged into an optical port of the corresponding rate, and connected to another optical port of the same rate in the same rack or an adjacent rack. The connection light is on. The price of DAC is also relatively cheap compared to two transceiver s plus a jumper.
