The biggest reason to buy is straightforward: these modules deliver dependable 1Gb copper connectivity up to 100 m with very low power draw and wide compatibility with open networking gear. Installation is instant and hot-pluggable, so they work well when replacing aging transceivers or adding copper ports to fiber-first switches.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGigabit performance:\u003c\/strong\u003e Supports 1000Base-T and a 1.25 Gbps signaling rate for standard gigabit Ethernet links over copper.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRJ45 convenience:\u003c\/strong\u003e Built-in RJ45 connector lets you use Cat5e or better cable to reach up to 100 m (328 ft) without extra adapters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide compatibility:\u003c\/strong\u003e Works with many open devices and branded SFP slots such as Cisco, Ubiquiti UniFi, Meraki, Mikrotik, TP-Link, Fortinet, Netgear and more.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow power:\u003c\/strong\u003e Designed for energy efficiency with power dissipation under 1.05W to reduce heat and overall power draw in dense deployments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHot-pluggable and MSA compliant:\u003c\/strong\u003e Plug-and-play behavior with SFP MSA and IEEE 802.3 compliance means no configuration is required for most switches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupport and warranty:\u003c\/strong\u003e Each module is tested before packing and the product includes 24\/7 customer service, 30 day returns, a 3 year warranty and lifetime technical support.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis 4 pack is ideal for administrators who maintain mixed fiber and copper environments and need inexpensive SFP-to-RJ45 converters that work immediately.
