TP-LINK MC200CM Gigabit Media Converter, 1000Mbps RJ45 to 1000M multi-mode SC

Nice product at great price. This product would be much improved with a few other features, even if the price were slightly higher. Features desired would be a housing with lights on the front and all connections on the back. Another nice feature would be the ability to support multiple Ethernet speeds (10/100/1000). This serves its purpose for me now, but if I need to use some of my older tech products on my optically isolated network branch, this will not work for my application. Still, this is a good product for its price. Sure... It's worth 5 Stars!

The product works perfectly. They last about 5 years, then the emitter light burns out. I have used this product in an installation connecting two server rooms about 200 feet apart continuously for 15 years, you just need to realize they eventually burn out. Until that happens, you get rock solid gigabit ethernet over fiber, immune to surges including lightning, on your data link. They are so cheap and work so well I can't complain, just keep a replacement on hand.

I bought this to electrically isolate my internet connection. My router and printer recently got destroyed in a lightning storm. We have a UPS for electric, but It appears that lightning struck the cable line and fried the Ethernet ports on the devices (the cable modem was somehow unharmed). I was considering surge protectors for cable lines, but saw mixed reviews. There is no way a power surge from the cable line can go over fiber. Worst case is the modem and cheap converter might get blown out.So far it's working great. I have a 150mps internet connection and I'm getting about 170 down, so it's definitely operating over 100mpbs.

We had the older version here at work that had the toggle switch on it and I was concerned that I would not be able to get the communication right between the older (ver 2.1 firmware) and this newer (ver 4.0 firmware) but it synced right up and worked like a charm.I question why we lost the older one already as it was only installed for a little over a year. Simply put, I was blinking on the FX all the time. It simply would not connect anymore. Replaced with this new one and up and running. -1 star for the length of time the original lasted, even though it was an older firmware model. Same item essentially.That being said, good price. We use these to run fiber in between buildings for two separate networks, the business side and my machine network.

Using this to bridge my outdoor PoE security cameras to protect my home network from nearby lightening, etc.It was easy to install.

The product worked great for about a year. Then, for no apparent reason whatsoever, both units died on the same day, leaving me with no ethernet in my media room. Amazingly disappointing. I know the fiber optic line is still good, because I tested it. Both units were plugged into expensive power conditioners, so I know that is also not the issue. They aren't expensive, but if they only last a year...

Bought 2 of these to upgrade a fiber link - however a week after they arrived a power supply running a different fiber transceiver on a different link died and I ended up using these to replace that set. They were a drop in replacement for the failed set so it was very timely that I got them. Also each transceiver appears to act as a switch since one of the transceivers is plugged into a 100baseT port while the other one is plugged into a gigabit switch port. I assume the fiber line that came up between the transceivers is running at gigabit.One thing I did not like is they used 9v power adapters instead of the more standard 12v power adapters. I really wish manufacturers would just standardize on the 12v 2A power adapter and not try shaving every last ounce they can off the power supplies. The power adapter wall warts are prone to being spiked and have a much higher failure rate than the devices they power so you have to assume that at some point you are going to have a wall wart failure.I also like that these have a power light in addition to the usual activity lights. Some of these transceivers only light up the activity lights when the fiber connection is made which means if you have a fiber cut the lights all go off and you can't tell if the transceiver is not getting power or not getting link. With these you can tell that.

I have had issues with my cable company and electric company using separate grounds outside the house. We have lost a lot of electronics over the years due to lightning and the improper utility grounding. Using a fiber optic break between the power and the cable eliminates the possibility of a lightning surge travelling from the cable company, arcing through the electronics back to the utility ground. I have been using these fiber optic converters for about ten years now and have had no more surge damage. Note that even a surge aerator outlet will not protect you if you power company and cable or phone company are not solidly grounded to the same grounding stake outside your home.
