TFC-PGSFP

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!

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.

The PoE powered media converter works great when you don't have access to an external power source. I've been using a pair of these for about 8 months with multi-mode gigabit SFPs and no issues so far.

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?

Really loud and intense coil whine, which I could almost live with, if not for the fact that it died after a little over a year. Kind of an expensive device to have this short of a lifespan, especially considering I have multiple much cheaper older units still going strong (not PoE though)

It's noisy. I had it installed to use Bell fiber internet; it works fine, but somehow it's noisy. There is a high-frequency noise coming from the case.
