Premium CAT5e cable ensures optimal performance in bandwidth-intensive Fast Ethernet crossover networking applications. Black Box GigaBase Premium CAT5e Crossover Patch Cables exceed ANSI/TIA industry standards ensuring optimal performance in bandwidth-intensive Fast Ethernet applications and guaranteeing the transmission of your data. They are perfect for making switch-to-switch computer-to-computer or other crossover connections. Tested to 350-MHz and 1-Gbps performance these cables exceed the 100-MHz CAT5e specification greatly reducing impedance structural return loss and near-end crosstalk (NEXT). A robust four-pair 24-AWG construction features 50-micron gold-plated contacts for superior conductivity. These cables have connectors designed for the insertion and extraction life of 750 cycles making for an ultra-reliable solution that you can count on to perform. They also feature snagless boots that provide extra strain relief and prevent connector damage due to cable snags during installation.
