10GBase-LR

These work good on OM4 and most OM3 but even on shorter OM2 their light emitting is weak. There are better models out there but these are a decent price. If you have OM2 that you are going to use these with I would look at more expensive models that have better emitters in them.

Working perfectly on my sg300 Cisco and am older netgear switch.

2 of 4 is actively working as expected. Best value.

They're all working great

It does what it’s supposed to do. Not much else to say.

I found myself in need of an extra ethernet port on my Ubiquiti Switch (US-24-250); rather than add another switch, I decided to move my uplink from a copper RJ45 port to one of the SFP based ports instead. I was surprised to see a 10Gb SFP come up on Amazon Vine to review, but I ordered it and waited patiently to arrive. Once it was here, I verified it worked in both Ubiquiti devices and ordered a second one out of pocket. The SFP is recognized immediately on insertion and has had no problems after connecting with some fiber I’ve had sitting around for years. Sadly, my switch only has a 1Gb SFP port, but both modules auto negotiated their speeds and has worked flawless ever since. I’m always a little leery of using unknown Chinese branded equipment, but it seems to work just fine. Also, this is internal to my network and can be monitored and firewalled before it goes outbound if it were to ever be a problem. Admittedly it’s been years since I’ve purchased SFPs for work, but I couldn’t believe how cheap these are compared to the Cisco ones bought in my past. I was skeptical, but would use them again if the need arose.

Snagged this 4-pack for upgrading my home lab's Ubiquiti UniFi switch to 10G multimode backbone, linking a NAS to servers over 150m of OM3 cable. Plug-and-play magic: Hot-swapped into the ports without a hitch, and they negotiated full 10Gbps duplex instantly—no firmware tweaks needed. The 850nm VCSEL lasers deliver crisp, error-free links with DDM monitoring showing stable Rx/Tx power (-1 to -8 dBm) even under load. Low EMI kept interference nil in my crowded rack, and at under 1W draw per module, they run cool without fans. Pros: Broad compatibility (nailed Cisco SFP-10G-SR, Meraki MA-SFP-10GB-SR, and MikroTik swaps seamlessly); supports OM1-OM4 up to 300m; rugged alloy shells with ESD protection survived a few accidental yanks. Value king—half the price of OEM packs. Cons: Dust caps are flimsy (lost one during install); illumination on the status LED is dim in low-light racks. Minor quibble: No individual serial numbers for tracking, but batch coding works fine. Verdict: If you're wiring 10G short-haul without splurging, these are a no-brainer for prosumer or SMB setups. Rock-solid for NAS/SAN/HPC; zero packet loss after 500+ hours of stress testing. Grab 'em before your network chokes.

These work fine

Fast. Doesn't heat up much

They work at 10Gbps. For the price, can't go wrong. I mean all I was expecting out of this product was that it would connect at 10Gbps and it does. Probably the best deal on Amazon for a 10G SFP+ Module.

Perfettamente compatibili switch ONTI. Prestazioni rispettate, privi di polvere sui trasduttori ottici. Non sono schermati sul perimetro di inserimento, c'è un minimo di passaggio di luce del modulo di segnalazione LED (non il trasduttore! solo il modulo di segnalazione di funzionamento). Da tenere presente nel caso di installazioni dove il requisito è necessario.
