## Long description

The TRENDnet TEG-S51SFP is an unmanaged 4-port Gigabit Ethernet switch with an additional SFP slot, designed for compact desktop or wall-mounted network installations. Its metal housing and fanless design provide quiet and durable operation while delivering a combined switching capacity of 10 Gbps. The switch supports 802.1p QoS for traffic prioritization, Jumbo Frames up to 9 KB, and rear-facing ports for tidy cabling.
Advantages
The metal enclosure with a magnet mount enables flexible placement and secure mounting. Fanless operation reduces noise and power consumption. The included SFP slot allows fiber connectivity and extended reach. 802.1p QoS maintains voice and video priority, and LED indicators show port status for simple monitoring. The device is plug-and-play and backed by a limited lifetime warranty.
Suitable for
Small office or home office desktop networks
Edge connections where a short fiber link is required
Environments needing quiet, fanless operation
Simple unmanaged network expansions and device grouping
