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

Just inserted in SFP ports of both switches, connected the LC duplex fiber optic cable, and it was online with no hassle. These are great SFP modules.

Very quick and knowledgeable customer service. Helped me out when I had an issue and offered a product that worked perfectly with my setup!

I did consider other similar types of mini-GBIC modules, but after getting overwhelmed with all the specifications, acronyms, and compatibility warnings, I lost patience and decided to purchase this one. Fortunately, it does work
