TP-Link TL-SM331T 1000BASE-T RJ45 SFP Module

Bridge the gap between your high-speed fiber hardware and traditional copper infrastructures with the TP-Link TL-SM331T 1000Base-T RJ45 SFP Module. Built in strict alignment with the Small Form Pluggable Multi-Source Agreement (SFP-MSA), this mini-GBIC transceiver instantly transforms an open SFP slot into a standard Gigabit RJ45 Ethernet port. Capable of extending your network reach up to 100 meters over standard copper cabling, it offers a cost-effective, high-performance solution for connecting IP cameras, access points, and VoIP phones to enterprise switches.

Key Features & Benefits

• Instant Gigabit SFP to RJ45 Conversion: Adds an extra high-speed 1000 Mbps copper port to your optical switches, edge gateways, or media converters seamlessly.
• 100-Meter Extended Reach: Transmit high-bandwidth data reliably up to 100 meters (328 feet) over standard UTP Cat 5e or above copper infrastructure.
• Plug-and-Play Simplicity: No software configurations or technical drivers required. Simply insert the module into an active port and connect your patch cables instantly.
• Durable, Low-EMI Metallic Housing: Constructed with a high-grade, fully metallic enclosure that guarantees excellent heat dissipation, blocks low electromagnetic interference (EMI), and extends hardware lifespans.
• Hot-Pluggable SFP Footprint: Avoid network down-times entirely. Install, pull out, or hot-swap modules on-the-fly without needing to power down active switch chassis stacks.
• Ultra-Low Power Consumption: Engineered to minimize heat dissipation and power usage across server racks, drawing just 0.5 W typical (0.8 W max).
