Dead easy to install and work as advertised. Will be buying a few more for the other shop. ### ⭐⭐⭐⭐⭐ Easy way to extend high speed LAN in the home. Better than WIFI. *by on Reviewed in the United States 14 November 2022* Needed to extend the fiber Ethernet connection from the router where in comes in from the service provider. WIFI 100 feet away in the home speed was much slower, like 75% slower.. With this pair of media converters and a single LC-LC fiber cable - 30 meters long does the job. Working bi-directional of a single fiber I get the same data rate as seen at the router, about 950 MBPS up and download with no data speed loss. Awesome technology. The transceivers transmit and receive on different wavelengths so it's full duplex. ## 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.us/products/558140415-a-pair-of-1-25g-s-bidi-gigabit-multi-mode](https://www.desertcart.us/products/558140415-a-pair-of-1-25g-s-bidi-gigabit-multi-mode) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-04*
