Will be buying a few more for the other shop. Review: I live in central FL, lightning capital of the US. I got tired of lightning strikes taking out my cable modem, my router, my switch and occasionally the Ethernet on my motherboard. So I bought these and installed them as an optical isolation break between my modem and router. 3 years on they are still working and I’ve had one modem toasted - but only the modem. I am switching to fiber Ethernet into my house so these no longer serve a purpose, but I thought I’d leave a review to praise them for the last 3 years of protection ## Features - What You Get: 2pcs Gigabit Multi-Mode Ethernet SFP Slot media converters; 2pcs SFP BiDi LC Dual Multi-Mode transceiver; 2pcs AC/DC Power Supply; 1 x User’s Manual.

This really cuts the cost and guesswork. works perfectly with os2 single mode cable and the armored outside cable as well...I couldn't be happier---will be ordering two more tomorrow! ## Frequently Bought Together - A Pair of 1.25G/s Bidi Gigabit Multi-Mode Fiber Ethernet Media Converter with 2PCS Bidi SFP LC Dual Transceiver Module Included, 10/100/1000Base-Tx to 1000Base-SX SMF RJ45 to SFP Slot 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 - 500ft/150m OD-5mm Industrial TPU OM3 Fiber LC to LC Outdoor Armored Fiber Patch Cable, Duplex Multimode Fiber Optic Cable, 10Gb, 50/125, Uniboot LC-LC with Pulling Eye Kit Installed on one end --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/558140415-gesd-a-pair-of-1-25g-s-bidi-gigabit-multi](https://www.desertcart.hr/products/558140415-gesd-a-pair-of-1-25g-s-bidi-gigabit-multi) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
