QNAP QSW-804-4C Unmanaged None Black network switch

The QNAP QSW-804-4C is an 8-port 10GbE unmanaged switch, allowing you to instantly upgrade your network environment at a cost-effective price. The QSW-804-4C supports 10GBASE-T and NBASE-T standards, allowing you to take advantage of higher network speeds with your existing Cat 5e and 6a cables. Both SFP+ (fiber) and RJ45 (copper) ports are available (with 4 combo ports) for servicing a range of network needs. Compliant with IEEE 802.3az (Energy Efficient Ethernet, EEE), the QSW-804-4C is energy efficient as well. With high performance, low latency and superb functionality, the QSW-804-4C is the ideal choice for upgrading your home or business network to support 10GbE connections.Faster speeds using existing cables with 10GBASE-T & NBASE-TThe QSW-804-4C is compatible with 10GbE and NBASE-T technologies to provide higher transmission speeds with existing cables. Depending on cable types and their lengths, different speeds can be achieved for faster, more efficient data transfers. The QSW-804-4C is also backwards compatible to provide connectivity with legacy devices.Flexible deployment with four combo portsThe 8-port QSW-804-4C switch offers four SFP+ (fiber) ports, and four SFP+/RJ45 (copper) combo ports for connecting different interfaces to the same switch. With RJ45 interfaces, 10 GbE is supported with Cat 6a (or above) cables. Alternatively, direct attach copper (DAC) cables can be used with SFP+ ports for connecting to servers inside a rack.
