      Great optics for my Arista switch. Plug-n-play, works like a charm for 100G over OM4. Reached full distance without issues. Will definitely buy from QSFPTEK again.

      Used to connect my 7280SR3-48YC8 with another 100G device within the cabinet of the company's data center. The transmission distance is about 30 meters, using OM4 multimode optical fiber. l plugged them into the QSFP28 port of the Arista switches, the device recognized it immediately without any compatibility warnings or errors.

      This 100G SR4 optical module is really easy to use! Just plug it into the QSFP28 port of the device, and it is very smooth when plugging and unplugging! Perfectly divide my four groups of 25G lines into eight-core MPO optical fibers, which completely matches the topology required by our project. It is exactly the same as described by the merchant, and the price is cheaper than other stores.

      Worked very well with my Arista DCS-7160-48YC6-F switch that we use to build our company's core network, so we are very conscious about product stability, well, from the results it was good.

      I have experience working with both Cisco and Juniper switches. Recently, I bought two 100 GB modules. Fortunately, these two modules worked two days after purchase. and everything is good now. These two modules arrived a week later after I purchase them. I'm happy to report that my network is running smoothly with the new module.

      Bought a pair for testing the switches. They match up nicely and everything works fine. Will consider buying more here as time goes on.

      We purchased this optical module here and one switch from another vendor. The module has very good packages and has been delivered quickly, but our network switches are on the delivery way...
