10GBase-LR SFP+ Transceiver 10G 1310nm Single-Mode - Reliable 10km

Our review of the 10Gtek 10GBase-LR SFP+ transceiver focuses on small data centers, network closets and prosumer labs that need a straightforward, long-reach 10G fiber link. The bottom line: this module delivers a dependable 10G connection over single-mode fiber up to 10 km with a standard 1310 nm wavelength, making it a practical replacement or spare for Cisco, Ubiquiti, MikroTik and other compatible switches. It is best known for functional compatibility and value, and it behaves exactly as expected in mixed enterprise and home lab environments.

Key Features

• 10G Data Rate: Provides a full 10 gigabit per second link capacity suitable for server uplinks and aggregation switches.
• 1310 nm Wavelength: Uses the common 1310 nm single-mode optical window for reliable distance performance on SMF.
• Up to 10 km Reach: Supports links to 10 km, useful for campus, metro ring segments or extended wiring closets.
• Dual LC Single-Mode Fiber: Standard dual LC connector ensures easy integration with existing fiber patch panels and transceivers.
• Wide Compatibility: Reported to work with Cisco, Meraki, Ubiquiti UniFi, MikroTik, Netgear and many open switch platforms, reducing sourcing friction.
• Pack Options: Available in multi-unit packs for stocking spares or outfitting multiple ports without reordering.

Who It's For

This transceiver is aimed at network administrators, system integrators and advanced home lab users who need an economical long-reach 10G module compatible with a wide range of switch vendors. It is particularly useful when replacing failed SFP+ modules in mixed-vendor environments or adding uplinks between buildings where single-mode fiber already exists.

Those who should look elsewhere include users who require multimode compatibility, shorter-range multimode optics, or modules with vendor-locked firmware and support contracts; organizations that need vendor-certified optics for formal warranty requirements should verify acceptance with their switch vendor before deployment.

Pros & Cons

Pros

• Solid compatibility across multiple brands, with customers confirming operation in Cisco, MikroTik and UniFi gear.
• Good value for the price, making it economical to stock as spares or for multi-port upgrades.
• Standard dual LC interface and 1310 nm single-mode optics simplify integration into existing fiber runs.

Cons

• Not vendor-certified for every platform, so some enterprise support teams may prefer OEM-branded optics.
• Limited to single-mode LC use and 10 km reach, so it is not suitable for short-range multimode applications.
