TRENDnet 100/1000Base-T to SFP Fibre Media Converter, Fibre to Ethernet Converter, RJ-45,Multi(SX) or Single-Mode(LX) 100Base-FX/1000Base-SX/LX Mini-GBIC Slot, TFC-1000MGA

Most of these media converters lock you into a fixed Ethernet speed of 100 or Gig-e. These don't, which is great. Assume you put a pair of these with a fiber in the middle - either Ethernet port on either end can be 100 or 1000 mb. Like an autosensing switch port. the TP-Links wouldn't do this - if one end is 100mb and the other is gig-e, it won't work. These will.I can't speak for long term reliability of these (yet) - though I will if I have any problems.Also, I like the way the screw loosens to remove the unit as card that can be placed into a rack unit with an optional dual-power supply. For a few more $ you can add an SMNP module to keep watch over them.Another nice thing is the way the LEDs work - if there's a fault (either a down link, etc) a yellow light will appear. If everything is working, then it's green. So at a glance, you can see if there are any faults in a bank of them.I'm using these with Mikrotik bi-directional SFP modules for single fiber links. Will update with reliability issues if I find as some of these will be out in the cold.

We use these to uplink to an ethernet port up too 3000ft away when we webcast events. Often times school gyms, field-houses or press-boxes wont have a network connection, so being able to long haul ethernet over fiber is a god-send.Often times, the cheapest option is the obvious choice, but in this case I chose the next to cheapest I could find for two reasons; first I have used TrendNet equipment before and know that they have a talent for balancing reliability, performance and price, and second, the realtek chipset that drives this medi converter is capable of actively matching different network types, while the other model I considered could only pass them through.The mix and match network conversion is the most important feature of this product, and one that is actually missing from many converters. What this means, is that you can match any 10/100/1000 wired network to any mini-gbic compliant SFP module, a 100m copper network to a 1.25g fiber module for instance, where many other converters would only let you go 1g copper to 1g fiber.As far as performance goes, I've used these several times on 100m and gigabit copper networks with foundry and zyxel 1.25g and 4.25g SFP modules and they've performed like champs! We rarely have our gear set up for more than two days at a time, but any drops in connection would kill us, and we havent experienced any on the media converters.

I use one with a fiber sfp for connecting my router via fiber to the ISP demarc (cat5). Mostly for direct lighting strike protection for my internal equipment. Indicator lights are great for troubleshooting link problems. Does a great job for my purposes!

Works perfectly. Chosen by recommendation and it came through. Used in a corporate network to link-convert a connection for two buildings and 48 port system. I attached it in a few minutes and it was up and running from the very second it got turned on. It has now been in use for a while and is easily recommended for business use. Great job.

Does exactly what I needed it to do - our carrier hands off high speed internet circuits with fiber optic and this is a great way to test the raw connection without having to drag a switch around. This device with the correct SFPs is like a Swiss army knife.

This is a great media converter. We use this device in a production data center environment to traverse traffic between providers. It functions as expected without issue. The price is great!

As expected.., a good quality device, simple and soundly constructed. Serving the purpose that it was acquired for. Satisfied with the purchase.

Everything Ok.

I chose to pay more for this converter given that it advertised link speed auto-negotiation. I can't really verify the impact of this since my fiber internet speed is current 150 down/up. However, the media converter was easy to set up and has been working perfectly. I am now running entirely my own gear and consistently hitting 160 down and up on my speed tests.The unit appears well built. Decent weight, nice solid metal for the enclosure. I took the board out of the casing just to check it out. When re-inserting it, be careful to line up the power jack with the cut-out in the back of the casing. Mine was caught on the side of the hole and I'm sure screwing it all the way in could have damaged or bent something. So just ensure they are lined up and the thing goes back in smooth.I had read in the reviews for many OTHER BRANDS that the media converters tend to run hot, with some people relating stories of units smoking as soon as they were plugged in (requiring a replacement). Well there is none of that with this bad boy. The unit has been plugged in for over a week now and it has never felt more than lukewarm. This gives me great peace of mind as I am less worried of the possibility of a media converter sparked fire in the wood closet where the gear is housed.There is one very small thing about this unit (and most other media converters) that I think could be improved. There is no control of the status LEDs. It would be nice to have a little switch or even just a sliding panel that could be used to black out the LEDs. Currently all my gear runs disabled LEDs and it would be nice to completely eliminate the glow from inside the closet. However, this is not a major issue as the LEDs can simply be covered with a piece of electrical tape. It's just nice when the manufacturer anticipates this need and includes a nicer, less hacky, solution.Oh and why not offer a 2.5Gbps or a10Gbps unit that can auto-negotiate with a 2.5Gbps fiber SFP module? I know Bell and possibly other fiber providers use these weird speed units. I think a media converter that could support the full 2.5Gbps speed of these SFP modules would immediately become the best seller.TLDR, this has been an excellent media converter for me so far. It performs well, has a good physical feel and the heat that it puts out is far below anything that I would consider worrisome or scary. The importance of this last point cannot be understated. If your media converter will be near wood or any other flammable material, why take the risk of starting a fire and losing your home just to save a few bucks? This was my thought process and I am very happy having chosen this TFC-1000MGA unit.

Bien emballé et excellent pour créer un pont optique sur réseau digital entre deux Switch.

Ordered trendnet for a backup set have no issues with using different vendor sfp single mode lc true line rate

I bought this for use with a GPON ONT module from Bell and it works great.
