DES-1016D is D-Link's basic 16-port Fast Ethernet switch for simple networks. It expands your router's 4 LAN ports to 16 wired ports for PCs, printers, old IP cameras, or POS systems. Since it's 100Mbps only, it's best if your internet plan is 100Mbps or less. If you have MTN 200Mbps/500Mbps fiber or need fast PC-to-PC transfers, it will bottleneck you. Unlike Tenda TEG1016G which is Gigabit, this one is older tech and cheaper. No PoE, so it cannot power Tenda i29/i26 APs directly. Good for small offices, shops, or home use where you just need more ports and don't need high LAN speed.
