Non-destructive Extension: The network cable connector helps you connect 2 network cables to extend the length of existing network cables without affecting network speed. It is an ideal choice when the network cable is not long enough. High Quality Material: The network coupler's housing is made of aluminum alloy, 360 ° shields the interference on network speed, such as EMI/RFI interference. The metal shell is shockproof and wear-resistant. The built-in PC plastic layer makes it heat and aging resistance. The gold-plated contacts are oxidation and plug resistant, can transmit network signals stably. High Standard Performance: The ethernet cable extender adapter supports POE, complies with ANSI/TIA/EIA 568C standard, support up to 10Gbps, 600MHz, suitable for CAT7 cable, backward compatible with CAT6A, CAT6, Cat5e, Cat5 version of the cable. Compact Size: The RJ45 coupler is portable and takes up little space, so it can be used to extend the cable in narrow spaces
