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!

Los transceptores son exactamente los que esperaba en excelentes condiciones. Muchas gracias.

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

Este producto no te defraudará. Además, el envío también es muy rápido.
