## Description

desertcart.com: 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 : Electronics

Review: So simple - These things just work. Quick and reliable set up. I used these to network my shop to my house.
Review: Warning: Do NOT get the fiber cable desertcart recommends! - 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 desertcart 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 desertcart 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.

## Questions & Answers

**Q: Why is one unit of the pair labeled "A" and the other labelled "B"? Is there a difference between the two units?**
A: Yes, these are sold as a pair, and pair consists of A and B units, and this is how they must be used - A in pair with B - because these WDM - Wave Division Multiplexing type units, that uses only 1 fiber to communicate with each other, and thus, A side will use 1310/1550nm and, B side - opposite of 1550/1310nm wavelength division. This is how these particular single fiber WDM units work

**Q: Anyone have a 450 ish ft patch cable that they can recommend? Doing a run through buried conduit.**
A: We have used some of the products from Fiber Cable Direct Store. Various lengths. So far, they have performed well. Be careful of snagging the connectors as we pulled a connector off on one pull.

**Q: hola no se mucho del tema, pero necesito una solución para que un local que esta a 200metros tenga internet de un moden lan. ¿esto es viable ?**
A: si con este equipo puede mandar internet a mas de 5 km de distancia atravez de una cable de fibra optica

**Q: Will this support full hd? will it support bidirectional communications with an ip pan/tilt/zoom camera?**
A: Typically full hd cameras will not consume more than 24mbit/s bandwidth, and since these are 1G (1000mbit/s) converters it is more than enough. But one thing you need to note, that these are non-poe media converters, so they will not power up camera via same rj-45 cable - power needs to be supplied separately

### ⭐⭐⭐⭐⭐ Great products, great value, great people!
*by P***R on January 7, 2021*

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!
