TRENDnet Gigabit Poe Pd SFP Fiber Media Converter, Poe Powered 100/1000Base-T to SFP Fiber Media Converter, Compact Design, TFC-PGSFP

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.

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

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.

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.

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

Unit worked as advertised. Only run for about 1 month though, so cannot comment on longevity. Separate power and link LEDs are nice for PoE powered equipment. Note that the copper interface will show link up even if the fiber is disconnected - sometimes this matters for failover detection, etc. Metal case is compact and nice.Biggest issue was the insane amount of coil whine my unit had, with two different PoE switches. Under anything more than idle traffic load, I could hear it from across a room! I only have one of these, so maybe I just got a particularly loud unit?

Bought these for use on those switches that didn't have enough fiber options, since all our upstream connections are fiber and we needed some additional redundant ports. Installed a few and they work well. Being POE powered (by Unifi switch) is extremely convenient- no power supply to deal with, and can reset the unit remotely as well. They work well, used generic single-mode FS modules with them, no problem. Nice status lights and unit is not crazy large. Hopefully they will last!

Bought 3 of these for a 10GB install. Not one of them would link up on fiber, or ethernet portsI used the exact model GBIC model recommended. I wasted a whole weekend on these- Returned everything and went with the Netgear switches with (2) 10GB uplink ports- they worked right away.Will never even consider this brand ever again. These are cheap and did not work at all for me
