Gigabit Ethernet Media Converter SingleMode Dual LC to RJ45 - 20km

In this review the Gigabit Ethernet Media Converter pack is assessed as a practical, no-frills solution for extending wired networks over singlemode fiber. It is best for IT technicians, small business owners, and installers who need a simple way to convert between 1000BASE-Tx copper and 1000Base-LX fiber without adding complicated management. The biggest reason to buy is reliability: the pair supports Gigabit speeds, 1310 nm singlemode links up to 20 km, and uses a stable RTL8213B chipset that keeps latency low and connections steady.

Key Features

• Convert Fiber to Ethernet: Converts 1000BASE-Tx copper to 1000Base-LX fiber (and vice versa) to extend networks up to 20 km using singlemode fiber.
• Gigabit Performance: The RJ45 port supports 10M/100M/1000M with auto-negotiation and MDI/MDIX auto-crossover for simple Gigabit connectivity.
• Singlemode LC Ports: Dual LC fiber ports run at 1.25 Gbps with a 1310 nm wavelength to support standard 1000Base-LX SFP modules for long-distance links.
• Stable Hardware: Built around an RTL8213B chip for consistent throughput and ultra-low conversion delay important for latency-sensitive traffic.
• Plug and Play: Hot-swappable modular design and LED indicators for TX, FX LINK/ACT, POWER, and FDX simplify installation and monitoring.
• Included Accessories: Two media converters, two 1000Base-LX modules, two DC adapters, and user manuals make the pair ready for deployment out of the box.

Who It's For

This pack is ideal for small offices, branch locations, or installers who need a straightforward fiber-to-Ethernet bridge without switching gear. It fits scenarios where a single copper Ethernet drop must be linked over distance to a central switch or where wall keystones need conversion to fiber.

It is not aimed at enterprise sites requiring managed features, advanced VLAN handling, or PoE passthrough; anyone needing centralized management or multiport aggregation should look to managed switches or multiport converters instead.

Pros & Cons

Pros

• Reliable Gigabit conversion with support for up to 20 km singlemode fiber links, useful for long-distance runs.
• Automatic duplex and MDI/MDIX handling makes hookup and compatibility with existing cabling easy.
• Includes SFP modules and power adapters for immediate deployment without extra purchases.
• LED indicators and plug-and-play design simplify troubleshooting and installation.

Cons

• Connectivity can be mixed in some environments; a few users reported inconsistent link-state propagation requiring local verification.
• Not a managed device, so it lacks VLAN, SNMP, or advanced diagnostics for complex networks.
