Tp-link Usa Corporation SM331T 1000BASE-T RJ45 Sfp

Product Description

The TP-LINK USA CORPORATION SM331T is a 1000BASE-T RJ45 SFP module designed to provide Gigabit Ethernet connectivity over copper cabling through a standard SFP slot. This module converts an SFP port on a compatible switch, router, or media converter into an RJ45 copper interface, enabling 1000 Mbps data transmission over standard Cat5e or Cat6 twisted-pair cable. It is typically installed by network technicians and IT infrastructure professionals working in enterprise or commercial environments where copper-based Gigabit uplinks are required.

The SM331T is suited for enterprise network installations where existing copper infrastructure needs to interface with SFP-equipped switching hardware. Typical deployment scenarios include connecting access switches to distribution-layer equipment, extending copper Gigabit links within a structured cabling system, and integrating copper ports into fiber-primary network backbones. It fits into any SFP slot that supports 1000BASE-T copper modules per IEEE 802.3ab.

Key Features

• 1000BASE-T standard support for Gigabit Ethernet over copper cabling
• RJ45 interface for direct connection to Cat5e or Cat6 patch cables
• SFP form factor fits standard SFP slots on switches, routers, and media converters
• Enables copper Gigabit uplinks without requiring a dedicated copper port on the host device
• Sold individually as a single unit

Compatibility

Designed as an OEM-style copper SFP module for use in enterprise switches, routers, and media converters equipped with standard SFP slots supporting 1000BASE-T copper operation.

Installation Notes

Installation should be performed by a qualified network technician. Power down or administratively disable the SFP port on the host device before inserting or removing the module where the host hardware requires it. Insert the module firmly into the SFP cage until the latch engages, then connect a standard RJ45 patch cable. Verify port negotiation and link status via the host device management interface after installation.
