Description
10Gbps Single-Mode Fibre Transceiver for Long-Distance Network Uplinks
The TP-Link TL-SM5110-LR is a 10GBase-LR SFP+ transceiver module designed for 10Gbps data transmission over single-mode fibre at distances up to 10km. Hot-pluggable and SFP+ MSA compatible, it slots directly into any 10G SFP+ port on compatible TP-Link JetStream switches and most third-party switches — making it a reliable, cost-effective solution for long-distance fibre uplinks in commercial networks, data centres, and multi-building installations across Australia.
Key Features
-
10GBase-LR, 10km Reach: Transmits 10Gbps data over 9/125μm single-mode fibre at distances up to 10km — ideal for inter-building and campus network links.
-
LC Duplex Connector: Standard LC duplex interface compatible with widely available single-mode fibre patch leads and infrastructure.
-
Hot-Pluggable: Insert or remove the transceiver without powering down the switch — minimising downtime during installation or replacement.
-
Digital Diagnostic Monitoring (DDM): Real-time monitoring of transceiver parameters including temperature, voltage, TX power, and RX power — enabling proactive fault detection and network health monitoring.
-
SFP+ MSA Compatible: Compliant with the 10G Small Form-factor Pluggable Multi-Source Agreement, ensuring broad compatibility with TP-Link JetStream switches and most third-party 10G SFP+ ports.
-
1310nm Wavelength: Standard LR wavelength for single-mode fibre, compatible with existing SMF infrastructure.
-
3.3V Low Power Operation: Energy-efficient design suitable for high-density switch deployments.
Common Use Cases
- 10Gbps fibre uplinks between access switches and core switches in commercial buildings
- Inter-building fibre connections on campuses, industrial sites, and business parks
- Data centre top-of-rack to aggregation switch connections
- Upgrading existing single-mode fibre infrastructure to 10Gbps speeds
- Long-distance NVR-to-switch uplinks in large CCTV installations

Frequently Asked Questions
What is the difference between 10GBase-LR and 10GBase-SR?
10GBase-LR (Long Range) uses 1310nm wavelength over single-mode fibre and supports distances up to 10km. 10GBase-SR (Short Range) uses 850nm wavelength over multi-mode fibre and is limited to distances of 26–300m depending on the fibre grade. Use LR for inter-building or campus links; use SR for short in-rack or in-building connections.
Will this transceiver work in non-TP-Link switches?
The TL-SM5110-LR is SFP+ MSA compliant, which means it is designed to work in any switch with a standard 10G SFP+ port. However, some switch vendors (notably Cisco and certain enterprise brands) lock their switches to accept only vendor-coded modules. Always verify compatibility with your specific switch model before purchasing.
What fibre cable do I need?
You need 9/125μm single-mode fibre (SMF) patch leads with LC duplex connectors on both ends. Ensure your fibre infrastructure is single-mode — this transceiver is not compatible with multi-mode fibre (OM1, OM2, OM3, OM4).
What does Digital Diagnostic Monitoring (DDM) do?
DDM allows the switch to read real-time performance data from the transceiver — including optical transmit and receive power levels, temperature, supply voltage, and laser bias current. This helps network administrators detect degraded transceivers or fibre links before they cause outages. DDM data is typically viewable via the switch's management interface.
Can I hot-swap this transceiver without rebooting the switch?
Yes. The TL-SM5110-LR is hot-pluggable, meaning you can insert or remove it while the switch is powered on and running. This minimises disruption during installation, replacement, or maintenance.
Is this transceiver suitable for CCTV installations?
Yes. For large CCTV installations where the NVR or core switch is more than 100m from an access switch, a fibre uplink using the TL-SM5110-LR is the recommended solution. It provides a 10Gbps, interference-free link over distances up to 10km — well beyond the 100m limit of copper Ethernet.
