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: Very simple install and usage. - It just worked for me, as is, out of the box. Powered it up, plugged in ethernet cable to switch, the 2 (Tx/RX) fiber leads, and instantly kicked in at 1gbps speeds. Simple instructions are included if you needed them, as well. ## Features - AUTOMATICALLY adapts to 10 Mbit/s, 100 Mbit/s (Fast Ethernet) or 1000 Mbit/s (Gigabit) Speed And Extends in over Multi Mode Fiber to up to 550 m – 0.34 miles - (Transmission Wavelength -– 850 nm, ST connector) - Supports Dual Speed Fiber Mode (configurable by dip switch) – Select 1000Base-SX or 100Base-SX – interconnecting with existing fiber nodes is easy with this media converter. Wavelength – 850nm, Use it with Multimode Fiber Only. - SUPPORTS Jumbo Frame & LLF feature - for increased end-to-end TCP performance - PLUG & PLAY - Simply plug in an ST optical port and UTP RJ-45 port, and it will work immediately - FREE UTP Cat5e Patch Cable (1m - 39in) Comes In The Set With Every Unit! - Colors May Vary Depending on Stock; ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #97,771 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #7 in Fiber Optic Transceivers | | Customer Reviews | 4.7 out of 5 stars 78 Reviews | ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/615GYWyXlIL.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/813qrfPSp0L.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/91eqnsnQBzL.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/71Nr8ThJDEL.jpg) ![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 - 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.
