It matches well with my device. And the customer service reply to my question fast. I get the product quickly.

Plug the modules in to Arista 7280CR2-60 and Arista 7260CX-64. And connect with 12 fibers type B OM4 trunk cable. Both recognize the optics.

Several 100G optical transceivers were needed since we'd like to conduct a trial 100G connection between our Cisco NCS 5001 switches. I confirmed with my account manager about the compatibility issues before placing the order. These QSFP-100G-SR4 modules worked perfectly on our switches. No compatibility problems so far.

Quite interested in FS's S5850-48S2Q4C switch for our 100G connection. I consulted with the AM about recommendations for some relevant matching products. She recommended these QSFP-100G-SR4 modules accompanied by several fiber optic cables for me. These optical modules operated perfectly with the switches. No complaints whatsoever!

The 100G SR4 optical transceivers are used for the 100G DWDM solution established by FS technicians two months ago in our plant. Only 4 channels were put into service and the rest reserved for future expansion. All went well. Moreover, the subsequent expansion is easy to figure out by ourselves. Brought home the right amount of coherent modules and 100G SR4 optics as the technicians instructed. Things now go smoothly as they did at the very beginning. Very good service and quality.

We needed new 100G modules to connect our devices Cisco N9K-93180YC-EX switches. Before ordering, we wanted to confirm whether the modules could be compatible with our switch type. So we asked the sales whether they could do compatibility testing for us. The guy contacted their technical team immediately and did the testing on the same Cisco switch type in their FS testing center. Then the sales showed the testing result to us. He also recommended the matched cable #68017 to connect our new modules.
After we ordered modules and cables on FS, the sales quickly arranged the delivery. The products were packaged and shipped from FS warehouse in Delaware. We received them three days later from UPS. Professional and solid package protected our items well, running with our switches, there is 0 dropped packet.

Bought four for our Arista switch (Model: DCS-7280SR2K-48C6M-FLX-F). The TX and RX power comply with industry specs. Great value compared to the original optics!

I want to connect Brocade MLx and EdgeCore 100BF switches using a pair of 100G QSFP28 transceivers. My AM recommended several types for me. Now the transceivers work flawlessly on my devices. No issues happened.

I bought these 100G transceivers for my Arista 7280CR2-60 and 7280SR2-48YC6 switches. Two months passed, they have been working without a hitch.

Nice Product.
