The GIGALIGHT Liquid Immersion SFP28 DAC GLS-PC250-XXC is a specially designed SFP28 Direct Attach Copper (DAC) cable for liquid immersion environments. It features hot melt glue for a protective layer to prevent liquid contact with the copper conductor, ensuring excellent signal integrity. The braided and shielding sleeve replaces the traditional outer jacket, reducing the risk of cooling liquid dissolving the outer jacket material.
