10GBASE-SR SFP+ Optical Transceiver Module Compatible with Cisco SFP-10G-SR SFP-10G-SR-S SFP-10G-SR-X 10Gbps 850nm 300m DDM Duplex LC MMF 4 Pack

I ordered this adapter hoping it would work. The switch was configured and it works like a charm. Will reorder when I get more equipment.

Building out my LAN and needed this for my switching capabilities. Plugged into CISCO switch without issue and was recognized. Only 5 ft distance, so reaching speeds was easy.

Installed this into a 10G capable switch and it worked just fine. Granted the distance was short as this was tested on the bench, but it worked well. I interfaced it to another brand SFP+ unit and both ends synced up just fine. The switch reported a 10300mb connection which is normal for a 10G SFP+ module. I am happy wiht the product and can recomend it.

I am building out my network at home so I got this for flexibility to connect to my planned NAS server.So far I don't have all the pieces to use this item but I like the solid built quality and it was packaged well.I expect it should work as advertised

Needed a 10g sfp for a Fortinet switch that was being installed. Used it to test and ensure it would work and then ordered one though the company. Keeping this as a test/temp replacement for future work.Didn't have to do much configuration out of the ordinary and getting the speed we expected.

I used this SFP transceiver to connect a Cisco Small Business SG550XG switch to an adjacent Meraki MS42P switch. I paired it with another brand of SFP+ module also rated for 300 meters, and a 0.2 meter MMF cable. Traffic passed, and the Meraki identified it by the parent brand name: "Fiber-Store - 10GBASE-SR: 10.3 Gbps (Part SFP-10G-SR85-UB, Serial: FBxxxxxx)."I tested it on both sides of the connection just in case, so I can say it worked on the Cisco Small Business SG550XG-8F8T and the Meraki MS42P switches. No complaints or issues.

I bought these to use between a Trendnet TEG-3102WS and a loaded Dell PowerEdge T610 I installed a Broadcom BCM57810S based dual-SFP+ pci-e controller into.It works, negotiated fine - it consumes the full 1G service Spectrum provides and works at 10G between my local 10G hosts. I tested this and the other transceiver on both sides successfully.Highly recommended!

Box says 10G, item is 1G.
