In general, I do believe quality comes at a price. However, someone has to explain to me why a Cisco-branded BiDi SFP sells for over $300 when this is a tenth of the price and works just fine. And now fs.com is my choice.

FS.COM is enough for me. The 100BASE-BX BiDi SFP quality is great for the price paid. Thanks!

I worried about the quality at the begining. I used it soon after it came, just out of my expectation, quality is great!

Always prompt with all my all orders, never been disapointed.

Very helpful staff, can always get someone knowledgeable via live chat quickly. Orders are processed quickly and prices are competitive.

Good job , I will cooperate with you again , because you have a very good price , amazing support and fast shipping.

Factory new parts and a great price. Items were in-stock and shipping experience was excellent.

Your website provided the items I needed at a reasonable cost, available when I needed them.

Good products, I was so happy with them I orded a few more and will now be using them as my go to SFP.

This was a nice deal online. I got warranty optics at an incredible price.
