TRENDnet 1000Base-T to SFP Fiber Media Converter, Compact Design, 1000Base-T RJ-45 Port, 1000Base-SX/Lx SFP Slot, Mini Gbic, Multimode, Single-Mode, Full-Duplex Mode, Dual Speed SFP, TFC-GSFP

Plug 'N Play without issue. Running now for over six months. Every speed test shows close to 10Gbps between a copper connected desktop 10Gb/s adapter, this interace and a fibre connected switch. Initially had a warranty problem which was easily & speedily resolved.

Never once linked up between a 10gb SFP+ switch and a 2.5gb cable modem. Tried numerous different branded modules. Returned.

The speed of the copper connection has to match the SFP+ port module speed. Cannot place a 1GB copper feed in from a modem and have a 10GB SFP+ module, only the port is backwards compatible to 1GB. Tested with HP, Ubiquiti, and no-name generic SFP modules, no issues with 800-900Mbps out of me business class hardwired connection. Ran an office that uses 2TB a month for a full day, no issues with heat or noise. Small form factor, decent device for the price.

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.

Bought this for a problematic Engenius ECW336 and BGW-320 that both run at 5GBE. I had been using SFP+ RJ45 modules but found them very vulnerable to overheating and silent packet loss. The media converter refused to link no matter what I did, including buying a second one and just using it as a giant ethernet cable. Use CAT 6/6a/7/8 copper cables, which link up in seconds, use these and nothing after 5 minutes. Still a cheap quality 10G media converter, so I had to install a Trendnet switch on the far end to change 5GBE to 10GBE. As soon as the WiFi 7 ECW536 ships next month, the replacement will use a faster 10GBE uplink thus removing at least part of this mess.

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.

Using these for building to building fiber. Full 1gb lime speed at 650m no problems. They have been installed in an outdoor enclosure for about 3 months now and have survived 15-100degree weather mounted to the side of the buildings. Been very happy with these for the price and stability I've seen so far.

Unless you need 1:1 conversion (10gbe to sfp+ at 10g) stay away.The manufacturer claims that it supports multi-gig, but it’s a deceptive claim. The unit only converts between two *matching* rates. Last I checked, the only “real” optical modules are 1G and 10G.If I bring in a 2.5gbe signal on the Ethernet side and bring in a sfp+ optic on the other, the device does not work.Putting an sfp+ to Ethernet adapter in the sfp+ port makes zero sense, so it really only works with 1Gbe/1G sfp or 10Gbe/10g sfp+There is no “multigig” support here, unless you’re playing with off-brand or boutique 2.5G/5G optics, which are silly, hard to find in a name brand, and generally more expensive than 10G optics.Stay awayyyyyy
