Single Mode SC WDM Single Fiber Bi-Di Gigabit Media Converter - Built-In Fiber Module 20km (12.42 miles) – to UTP Cat5e Cat6 10 100 1000 RJ-45 – Auto Sensing Gigabit or Fast Ethernet Speed -1 pair

This set of media converters work perfectly, offering full duplex communication over a single fiber. But make sure you consult with the manufacturer for the correct fiber type, because the one AMAZON is showing in this ad, under the category of items (frequently bought together) is the wrong cable and will not work! The correct fiber type for these adapters is SC/UPC-SC, and will have blue connector ends. Again, the ones AMAZON is showing will NOT work.For background, I use these media converters between my modem and router for additional isolation/protection from external surges. The switching power supplies offer reasonable ground isolation, while the fiber provides a path through which no electrical surge can pass. I've used other fiber media converters in electric utility substations for similar protection, to isolate sensitive equipment from remote sensors near high voltage buses. There has been no loss in internet functionality or speed with this addition, in fact various internet speed tests show identical results.

These things just work. Quick and reliable set up. I used these to network my shop to my house.

The pair of units were tested with a single optical fiber. Within seconds the communication was established at 1Gbits/seconds. The units are compact, low power and have good shielding. No EMI were detected outside the enclosures. I used a 5 Meters SC to SC Fiber Optic Cable Single-Mode for this test. I recommend the product and customer service has been responsive to my inquiries.

Was not familiar with this company but was looking for a device to replace a 100 fdx device in order to achieve gigabit speed over single mode simplex fiber (device I replaced was Planet Fast Ethernet Bridge 10/100Base-TX). If you are looking for a solution outside of an sfp module, I recommend this device.Ran several tests over the fiber link and I was consistently receiving just under 900 Mbps with little to zero packet loss. The test I was using was a powershell script that would write a dummy file to a mapped drive on the other end of the fiber. To make sure the 900 Mbps was a hard drive limitation and not a bottle neck at the media converter, I ran the same test on the same network segment (not going through the fiber) and the results were comparable.Compared to the media converter it replaced, it runs cooler and seems to use less power which surprised me considering the speed advantage.The only semi negative thing I can find about the device is that I am not sold on the inline power brick as opposed to the power brick being on the charger port. It's not a major issue, just requires little work to tidy up the installation.

We needed a device to go from fiber to ethernet. This was not the device for that. It goes from Ethernet to fiber. It does act as an Ethernet extender via fiber by going from Channel A to B. Transmit box to receive box. Appears to be well made, tho we did not end up using it.

I was having problems with some other media convertors (10Gtek) working between Fortinet switches. It seems they don't all support the QinQ or VLAN Stacking that Fortilink apparently uses to connect between devices. These do support QinQ and my Fortiswitches connected up flawlessly after installing them.

It was as simple a “plug and play” device as I have encountered anywhere, and did exactly what I wanted. I am now expanding my system with more devices from ad-net and am working with their excellent customer support team to get the best set of products for my needs. They have helped me avoid what would have been a long-term design mistake. So, not only great value and quality, but an excellent team to back it up!

Worked perfectly 1200 meter run, allowed us to use the 2nd fiber in our pair for a separate network
