The fiber was 62.5/125 OM1 multimode. By the time I realized that for the same price I could have gone with something better the fiber was already buried and I thought I was doomed to 100mBit forever. Recently I started to look again and found 1000Base-LX and and mode conditioning cables. I went down that path, but through a series of wrong parts shipped didn't get a fully set of hardware yet. Meanwhile I found these guys and thought I would give them a try. They worked perfectly on my existing setup. According to iPerf benchmark I get 950mBit over my 1000ft of 62.5/125 to a couple to another 350ft to the shop. I couldn't be happier with this product. Review: Did what it claimed - It ran gigabit over an OM1 cable. I think this deserves caution as cables may not always be built beyond spec. But as an endpoint it did its job. ## Features - MULTIMODE ST, 550 m (1,804 ft) OVER 850nm FIBER: converts Gigabit Ethernet to multimode ST fiber and back. Works with OM1, OM2, OM3 and 62.5/125 or 50/125 multimode cable. The ST fiber module is built into the unit and factory-aligned - nothing to fit, match or configure. - AUTO-SENSING 10/100/1000 COPPER: the RJ-45 port negotiates speed and duplex automatically, so it links to whatever switch, router, NAS, PC or IP camera you connect. Jumbo frame support up to 9000 bytes for full throughput on file and backup traffic. - BUY TWO FOR A FIBER RUN: use ONE if the far end already has a multimode ST fiber port on a switch. Use TWO, one at each end, to join two copper devices over a fiber run. Ships with a 1m Cat6e patch cord so the copper side is ready out of the box. - MULTIMODE ONLY - CHECK YOUR FIBER: the fiber side is 850nm multimode with a built-in ST connector. It will NOT link over single-mode fiber or with a different connector type - if your run is single-mode, pick the matching model instead. - BUILT FOR THE JOB: fanless with no moving parts, desktop or wall mount, standard AC power. Works with any IEEE 802.3 switch, router or NIC - no drivers, no configuration, no management software. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #110,563 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #7 in Fiber Optic Transceivers | | Customer Reviews | 4.7 out of 5 stars 80 Reviews | ## Images ![Multimode ST Gigabit Fiber Media Converter to Ethernet RJ45, 550m/1804ft - Image 1](https://m.media-amazon.com/images/I/615GYWyXlIL.jpg) ![Multimode ST Gigabit Fiber Media Converter to Ethernet RJ45, 550m/1804ft - Image 2](https://m.media-amazon.com/images/I/813qrfPSp0L.jpg) ![Multimode ST Gigabit Fiber Media Converter to Ethernet RJ45, 550m/1804ft - Image 3](https://m.media-amazon.com/images/I/91eqnsnQBzL.jpg) ![Multimode ST Gigabit Fiber Media Converter to Ethernet RJ45, 550m/1804ft - Image 4](https://m.media-amazon.com/images/I/71Nr8ThJDEL.jpg) ![Multimode ST Gigabit Fiber Media Converter to Ethernet RJ45, 550m/1804ft - Image 5](https://m.media-amazon.com/images/I/81g5uxnr53L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great to upgrade old multimode lines. *by E***D on July 30, 2019* I put in fiber between the house (where the internet comes in) and the workshop (where my home office and servers are) years ago when 1mBit was the best our ISP could offer.

I think this deserves caution as cables may not always be built beyond spec. But as an endpoint it did its job. ### ⭐⭐⭐⭐⭐ Being fair *by R***Y on December 6, 2022* Let me be totally transparent, I had to return this item due to the fiber being damaged, replacing the media connection was the least of my worries. The item is easy to connect and worked perfectly on my fiber jumpers. ## Frequently Bought Together - Multimode ST Gigabit Fiber Media Converter - Built-in ST Fiber Module 550 m (0.34 Miles) 850 nm - to UTP Cat5e 10/100/1000 RJ-45 – Auto Sensing Gigabit or Fast Ethernet - Jumbo Frame - LLF Support - StarTech.com 2m Fiber Optic Cable - Multimode Duplex 62.5/125 - LSZH - ST/ST - OM1 - ST to ST Fiber Patch Cable (FIBSTST2) Orange - OpZonik 1M ST to ST Fiber Optic Patch Cable Multimode OM1 Duplex 62.5/125µm Optical Patch Cord 1G/10G Fiber Optic Cable ST-ST 1 Meter (3.2ft) --- ## 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/74015970-multimode-st-gigabit-fiber-media-converter-to-ethernet-rj45-550m](https://www.desertcart.hr/products/74015970-multimode-st-gigabit-fiber-media-converter-to-ethernet-rj45-550m) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-31*
