Tp-link Usa Corporation SM311LS Gigabit Sfp Module

Product Description

The TP-LINK USA CORPORATION SM311LS is a single-mode gigabit SFP transceiver module designed for use in managed switches, media converters, and other network equipment with SFP expansion slots. It converts electrical signals to fiber-optic signals, extending network reach well beyond the distance limits of copper cabling. The SM311LS is suited for structured cabling installations where long-distance, single-mode fiber runs are required. Network technicians and low-voltage cabling contractors are the primary installers for this type of module.

The SM311LS is used in commercial and industrial network infrastructure applications where gigabit fiber connectivity is needed between switches, routers, or other SFP-capable devices. It is appropriate for backbone runs in building distribution systems, campus networks, and data center environments where single-mode fiber plant is already in place. This module ships as a single unit.

Key Features

• Single-mode fiber support for extended transmission distances
• Gigabit (1000 Mbps) data rate
• Standard SFP form factor for broad equipment compatibility
• Hot-swappable design allows installation without powering down the host device in most cases
• Sold as a single module per package

Compatibility

Designed as an OEM-style SFP transceiver for use in gigabit-capable network switches, media converters, and routers equipped with standard SFP expansion slots.

Installation Notes

Installation is performed by qualified network technicians or low-voltage cabling professionals. Before inserting or removing the module, confirm whether the host device supports hot-swap operation; if not, power down the switch or converter first. Clean fiber connectors with an appropriate fiber-optic cleaning tool before mating to avoid signal loss. Follow TIA-568 and applicable local structured cabling standards during fiber plant termination and labeling.
