Very Impressive and Fast
5 stars. This item is for single mode fiber connections. It works flawlessly. 2 modules were purchased and just seem to be non functional but the other is working. I will be buying more. Over 50 devices are controlled by this item Insert sfp module, connect power to switch, then insert fiber cable. That’s it

Works great with Ubiquiti!
Worked great for my Ubiquiti US-8-150 to US-24-500 switches. Recognized immediately when using 9/125 OM2 fiber.

Solid Value - Plug in perfect - works perfectly
Needed a pair of CISCO SM OPTICS modules ASAP and had to be direct plug compatible. True name brand CISCO modules cost 20x or 30x more and are semi constrained due to logistics and supply chain issues. The packaging is unusual (metal box) but who cares. They worked.

Has lasted several months
Fair SFP units with their own chips and firmware. Not 10 or 40 Gigabit capable, like you would want in any new system, but they’re what we have on this marketplace, and have lasted for several months reliably, unlike some other multimode units I’ve used in the past. They are easy to slide and clip into device SFP sockets/ports, and are tight fitting yet loose enough for sheathed reinforced fiber optic lines, very easy to install. Heat level is 18.3 Fahrenheit over a 75F ambient environment with no data being transmitted, or about as much as a 3 decade old ceiling fan motor on medium. If the manufacturer wants to tell me how to update their firmware, if they offer updates, please send a message.

plug and play, stable connection, cheap
Used these on a pair of Netgear GC110 switches spanning ~360ft between 2 buildings. Works great, stable 1gbps connection.

It just works.
This is my second set of these that I have ordered. They are all running in Mikrotik switches / routers. Just pop them in and they work out of the box. One set even survived a lightning strike (the hardware they were in was not so lucky).

Not compatible with either my Cisco 897 router or with my Nexus 9K switch. Keep getting unapproved/ unsupported messages in console - not sure how the seller can claim GLC-LH-SMD compatible when its not.

Además de las marcas indicadas, preguntando con ellos indican si los es para modelos concretos de otras más. Mejor relación calidad-precio del mercado, veremos la durabilidad.

Direct plug and play with dell 6200 series powerconnect switch and intel x520. No issues at all, connection is stable via 250m os2.

Transceiver que j'utilise sur un Mikrotik crs305-1g-4s+in, et un adaptateur usb3.0/sfp. Aucun problème de compatibilité, marche impeccablement jusqu'à maintenant, à voir sur la durée.
