    We had a positive experience with the 40G SR4 and MTP cable. They performed as expected, and our Cisco 2960S accepted them with no problems. Additionally, the price was reasonable, and the service was exceptional. We will definitely consider using qsfptek as a priority supplier for any future needs.

    Initially, I harbored reservations regarding the caliber of the product prior to acquiring it. However, the sales manager's assiduous elucidation of their return policy allayed my fears. Moreover, the fact that they offer a five-year warranty and 24/7 customer service brought about a sense of comfort and led me to endorse procuring from QSFPTEK.

    I bought their optical modules once last year and had no problems with compatibility. So this time I ordered the switch again, and it is now well connected with my equipment, the signal is more stable and the transmission rate is fast.
