The QSW-308-1C is a 3-port 10G SFP+ and 8-port Gigabit Unmanaged Switch, providing three 10GbE SFP+ ports (with one 10GbE SFP+/RJ45 combo port) and eight Gigabit ports. The QSW-308-1C allows you to instantly upgrade to a hybrid high-speed network environment at a cost-effective price and is compatible with 10GbE and NBASE-T technologies to support up to five speeds (10G / 5G / 2.5G / 1G / 100M). The SFP+/RJ45 (copper) combo port also provides higher transmission speeds when used with existing cables. With its desktop size and silent operation, the QSW-308-1C perfectly blends into homes and offices while providing high performance, low latency and superb functionality.
