1.25G SFP 1000Base-SX, 850nm MMF, up to 550 Meters, for Cisco GLC-SX-MMD/SFP-GE-S, Meraki MA-SFP-1GB-SX, Fortinet, Ubiquiti UniFi UF-MM-1G, Mikrotik S-85DLC05D, TP-Link TL-SM311LM and More, Pack of 2

These things work great. Fired up first try with my 10Gtek 1.25G Media Converter SFP and my Cisco SG11224NA switch with 15m of OM4 in between. Works great!

You just like when you buy something and it works. Yep it does. Only been using it a few weeks but no errors or issues so far.

Installed 4 modules in 802.3ad between an Engenius EWS1200-28T and an Engenius EWS1200D-10T. It was plug and play and works great with 10 Gigabit Aqua Fiber Optic Cable, LC/LC, Multimode, Duplex (#B01735WPSE). Photo: Engenius EWS1200D-10T with 10Gtek modules installed and connected with 10Gb LC multimode fiber.

I was skeptical but these worked perfect.

I had no issues installing and getting these SFPs to work. Excellent product for the cost!

Producto de muy buena calidad, desde mi punto de vista no le pide nada a ningún otro fabricante. Cumple con los estándares mencionados. Lo tengo funcionando en 2 escenarios. Fortigate a Cisco y el otro de Cisco a Cisco.

Works as advertised. Used in a Cisco SG350-28. Plug and play.

good product, worked as expected

I have ordered loads of these transceivers. And so far, I have yet to come across a device that doesnt like them. Works in brands like ASUS, QNAP, Mikrotik, Sonore and too many media converters to list. I really like these due to their reliability (using my first pair since early May of 2021 and they just work right out of the box. Not plug and pray like some others Ive bought!

These work pretty great. I wish my switches supported 10Gb SFP+ ports, but the switches I have will only support the 1.25Gbps SFP switches. These are not only a great price, they work flawlessly with cisco switches. I have a catalyst 3950 (an older model from 2k6) and I have a SG-220 26p switch for small/medium business and they will xfer the full bandwitdth at low latency to one another.
