I purchased two of the 1.25Gb/s SFP Module to 10/100/1000Base-Tx, with a 1.25G 850nm 550M SFP media converters and plugged one in on each side and connected the fiber. I removed my 50' ethernet cable and plugged a 3' one directly between the cable modem and media converter. I did the exact same thing on the other side and everything came up immediately. Lost a total of 5 pings, and my routers IP address did not change. (the cable modem has no idea these are in-between). As far as a performance test goes, my average ping time to my cable modems default gateway may have went up by about .25ms average over 100 packets, but that could just be the neighborhood I am in. I am more than pleased with this simple solution to protecting my network from a lighning strike on the cable lines around my house. Also - I purchased a 3rd one as well as a 10Gtek for Cisco GLC-SX-MMD/GLC-SX-MM/SFP-GE-S, Gigabit SFP SX Transceiver to plug directly into my network switch. I just trenched a 6-10" trench to my shed and will be placing the media converter in there along with an access point which is about 80' from the house plus about 35' of internal cable. I have already tested the 3rd one along with the SFP module in my switch and they connected right up. As long as I dont have any issues running the fiber, this is another great use for these to protect my internal network from both near lighning strikes as well as static differential between the buildings. While I cant take advantage of POE (Power Over Ethernet) to power the aceess point, I think the isolation definatly outweighs the benefits of POE. So far I have less than 30 minutes with these in use (2018-10-21). If you dont see an update from me, they are still working. Review: Using for Lightning Protection - I am using two of the media converters connected together with a short one meter fiber optic patch cable to provide Lightning isolation Protection to my local Intranet after sustaining several destructive Lightning events that came in over my under ground telephone/ DSL cable. The system is working well and I see no speed reduction. The 10Gtek converters are well made and impressive in their small size, zero configuration, and low cost. What more could I ask for. I would recommend them. Ken.

I'm a big fan of the metal case. However, the price isn't the best. You can get one without an SFP transceiver and just buy your own transceiver off eBay. Cheap ones are plenty fast enough, and I found a 4Gbit one for less than $2 including shipping. The TP-Link alternative is about the same, metal case and all, but cheaper if you add your own transceiver. ## Frequently Bought Together - 10Gtek Gigabit Ethernet Media Converter with a 1000Base-SX Module Included, MMF Dual LC Fiber to Ethernet RJ45 Converter for 10/100/1000Base-Tx to 1000Base-SX, UL Certified, up to 550m - FLYPROFiber- LC to LC Fiber Patch Cable 1M/3ft, OM3 Multimode Fiber Optic Cable Cord, 10GB/40GB, Duplex, 50/125um, LSZH, Options: 0.2m-200m - 10GTEK 1.25G SFP 1000Base-SX Multimode LC Fiber Transceiver Module, 850nm MMF, 550m, for Cisco GLC-SX-MMD/GLC-SX-MM/SFP-GE-S, Meraki, Fortinet, Ubiquiti UniFi, Mikrotik, Fortinet, TP-Link, Netgear --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/46725308-kit-1-550-m](https://www.desertcart.pt/products/46725308-kit-1-550-m) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-28*
