The TP-Link TL-SM331T 1000BASE-T RJ45 SFP module provides reliable gigabit network speeds over copper cable. It’s hot-pluggable and supports IEEE Std 802.3-2002, and features a fully metallic enclosure to reduce EMI. Its low power dissipation (0.5 W typical, 0.8 W max) and operating temperature range of 0-70C makes it an ideal choice for any commercial application.
