Fiber does not propagate electromagnetic interference
I used two of these along with the TP-Link MC220L converter to upgrade my Eversolo T8 and it worked great!

No Complaints
Bought this as part of an Ethernet bridge to get my home LAN out to my detached garage (WiFi was not reliable). The system is working wonderfully! Paired with TP-Link Gigabit Ethernet Media Converter, Up to 1000Mbps RJ45 to 1000Mbps SFP Slot Supporting MiniGBIC Modules (MC220L) , one on each end of a fiber line. No complaints.

Work just fine on a business install linking our two buildings (i'd estimate 2000 feet of cabling between us). Had to "trick" our cisco 2960 catalyst switches into accepting these modules but that is literally a 10 second process and a few lines of telnet code

Works Great!
Works Great along in SFP port of TP-Link POE Switch and TP-Link Jetstream Switch! Used a Cable Matters 10Gb 40Gb Multimode OM3 Duplex 50/125 OFNP Fiber Patch Cable LC to LC for the connection.

Good product
Bought this to use with my TL Link Gigabit Media Converter. Works well. Decent shipping. Would be nice if it wasn't so expensive for such a tiny piece of equipment.

Packaging Mix-Up
I received my order as expected for the Single-Mode Model. All of the packaging had the single mode model number, the transceivers had a sticker on them with the single mode model number, but the transceivers themselves had black tabs and the factory etched Multi-Mode model number. I double checked my order and I had ordered the Single Mode variant. A lot of great reviews and I’m sure a ton of these work great, but I couldn’t even test these because I received the wrong model.

Works great on SOTM SN10G SFP port switch. This is a 1G module. Have purchaed Finisar 1475 which is 10G bandwidth module however SOTM switch cannot support 10g.Users might want to tale note. Sound wise, clear as a whistle no issues so far as am using this TPLINK module daisy chain to another SOTM SN10G. With fibrepro 7" length LCLC os2 .You can buy the whole wide web of modules to try and narrow them down to the best sound for any audiophile given switch but I find that it is a waste of money and time.You are better off playing LPs.However for TIDAL streaming does works fine for me and have tested playing back and forth from a ripped to wave cds 44.1/16bit direct from cocktail x40 thru uab (sotm usb ultra onboard clock) and with Lenovo laptop also with Sotm txusb ultra, TIDAL, the tidal does sound slightly similar but take note though, the decay of the cymbals ended (faster)lesser last note shimmering decay effect. Softer no bite.No air surrounding the cymbals.No idea why?All psu are plixir balance elite .Amps are Belcanto ref500s to Mytek broolyn dac+ and cables kimber ks1021/ pk10 palladian /ks2036/8tc.SR fuaes amd bybees with shakti stones and shakti onlines.SR tranqua bases. Update 1 Now having bought 08 and no issues at all. Only for LC to LC fibres and OS single mode SM single mode. Do not use OM or MM multimode. Do not mix the IN and OUT of the module.Wise choice to go with same module maker/ model nbr.

I bought these in order to convert my ethernet signal to fiber and they did the job although for audiophile listening there are better but more expensive options.
