A Pair of Gigabit Single Mode LC Fiber Media Converter, with 2 Pcs SFP LX Modules, 1.25G/s Fiber to Ethernet Converter, 1000Base-LX to 10/100/1000base-TX, SFP to RJ45, SMF, 1310nm, up to 20km

Quick take

This two-pack media converter kit turns gigabit RJ45 Ethernet into single-mode fiber (1000Base-LX) using LC SFP modules at 1310nm. It is built for plug-and-play deployment when you need to extend an existing gigabit network across fiber, with jumbo frames support and simple link status LEDs. The main thing to confirm before buying is that your fiber type and LC single-mode SFP/LX pairing match your intended distance.

Pros and cons

Pros

  • Gigabit bridge design, RJ45 to single-mode LC fiber (1000Base-LX at 1310nm)
  • Plug-and-play setup, no configuration required
  • Jumbo frames support (up to 9K bytes) for compatible networks
  • Status LEDs for TX, FX link/activity, duplex, and power

Cons

  • Distance and link reliability depend on using the correct single-mode fiber and the intended LX setup
  • Best suited for Ethernet extension, not for higher-speed or multi-gig deployments

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence is limited in detail, but it consistently points to an easy setup experience. Multiple reviewers describe the converters as straightforward to install (plug it in and use), with fast connectivity once linked. The general theme is “works as expected” for short-to-moderate fiber runs, with no recurring reports that suggest widespread configuration complexity or systematic performance problems. At the same time, the review sample is not large enough to reliably map out edge-case behavior like long-distance stability across every fiber run type.

Who this is for

This converter pair is a strong fit when you need to connect gigabit devices across a fiber link without replacing your existing copper infrastructure. It is especially useful for:

  • Extending existing gigabit Ethernet runs where one side is copper (RJ45) and the other side can be fiber
  • Point-to-point fiber bridging using single-mode LC fiber with 1310nm 1000Base-LX
  • Installations that value simplicity where plug-and-play operation matters

Key features that matter in day-to-day use

Gigabit Ethernet bridging over single-mode fiber (1000Base-LX)

The kit is designed to move a gigabit Ethernet link between RJ45 (10/100/1000) and single-mode fiber using LC connectors. It uses 1000Base-LX optics at 1310nm (with SFP LX modules included), and it is intended for fiber runs up to the stated single-mode range (up to 20km).

Plug-and-play behavior

Configuration is not the focus here, the product is designed to come online quickly when you connect the Ethernet and fiber. It supports IEEE compliance for standard Ethernet operation (including typical gigabit Ethernet expectations), and it includes auto crossover (MDI/MDI-X) behavior on the RJ45 side.

Jumbo frames for compatible networks

With jumbo frames support up to 9K bytes, it can be helpful on networks that are already configured to use larger frames. If your endpoints switch ports or devices are not configured for jumbo frames, you can typically operate normally, but jumbo frame behavior only helps when everything along the path supports it.

Status LEDs for faster troubleshooting

Instead of guessing what link is up, the unit provides LED indicators tied to power, fiber activity, copper activity, and duplex. That makes it easier to validate connectivity during installation and when diagnosing “no link” moments.

Pros and cons (expanded)

Pros

  • Two converters in one kit, which is convenient for a matched copper-to-fiber endpoint setup
  • Gigabit speed support (1000Mbps on the RJ45 side when linking at gigabit)
  • Single-mode LC fiber optics at 1310nm with LX SFP modules included
  • Jumbo frames (up to 9K) for networks that support it

Cons

  • Fiber type matching is crucial, because single-mode LX performance depends on using the right fiber and optics pairing
  • It is not a “general transceiver replacement” for every scenario, it is specifically a fiber-to-Ethernet converter bridge for 1GbE

Price and availability

Current pricing can vary, so check the latest cost before ordering. This is positioned as a budget-friendly way to add fiber capability to an existing gigabit Ethernet setup, especially when you need a matched pair.

Verdict

If you need to extend a gigabit Ethernet connection over single-mode fiber using LC 1310nm (1000Base-LX), this pair of converters is a practical, easy-to-deploy option. It shines for straightforward installations where plug-and-play operation, link visibility LEDs, and jumbo frame support (when your network is configured for it) are priorities. Just make sure your fiber is the right single-mode type, your LC cabling is compatible, and your distance expectations align with the LX use case.

Alternatives to consider

Reviewed productBuy on Amazon
  • Fiber switches or media converters with different optics: if you need different fiber types, different wavelengths, or more ports, a switch-based approach may be cleaner than point-to-point converters.
  • Higher-speed fiber equipment: if your network targets 2.5GbE, 5GbE, or 10GbE, this gigabit-only bridge may cap performance.
  • Managed fiber solutions: if you require advanced monitoring, VLAN controls, or traffic policies, a basic transparent converter may not be enough.

FAQ

Is this a plug-and-play media converter?

Yes. The kit is designed to work without configuration when you connect the RJ45 and fiber sides, using Ethernet auto negotiation and auto crossover features on the copper port.

What kind of fiber does it use?

It uses single-mode fiber with LC connectors and 1000Base-LX optics at 1310nm, with SFP LX modules included. Your cabling should match a single-mode LC setup for best results.

How far can it transmit?

It is intended for single-mode links up to the stated distance (up to 20km). Real-world performance depends on your fiber quality, link budget, and proper optics matching.

Does it support jumbo frames?

Yes, it supports jumbo frames up to 9K bytes.

Does it work with gigabit Ethernet devices?

It is designed for gigabit Ethernet bridging, with RJ45 support for 10/100/1000Mbps and fiber-side support for 1000Base-LX.

Is this suitable for a network that needs higher than 1GbE?

No, it is aimed at 1GbE. If you need multi-gig or 10GbE throughput, you will want networking gear that matches those link speeds.
