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.

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!

Using this and the companion TrendNet TEG S51SFP, the digital end of my stereo is cleaner sounding. All together as far as the world of audio goes amongst the least costly way to tweak one's system.Basic Set-Up:Router > TEG S51SEP (via CAT6)> TFC GSFP/A via fiber > DAC endpoint via ethernet.You can also use two of these devices if you do not need extra ethernet ports.

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.

Everything Ok.

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.

These are cheap and get the job done, but they have a really high failure rate overtime. We deployed about 40 of these and about 25% of them have failed within a year.

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.
