I have to say, Your customer service, notifications, pre-sales info, shipping speed/checkout, have been fantastic.

Very quick shipping and got what i ordered.

We can talk, learn from, select, and order from FS non-proprietary components and parts. FS is basically a really good vendor of many suppliers for ground commercial applications.

We tested the module, it works very well, it is much higher quality than other competing products.

FS.COM is great. I have ordered several things from them. It's all gone great. The modules work as advertised. Our equipment accepts them very well. Really 25Gbps achieved. Usually, their modules all work as efficiently as our original ones.

These 25G modules are well suited for our use in a somewhat rough environment. They have done a very good job. No error occurs and troubles made. Optical transmitting and receiving all perform within the reasonable range. A quite reliable choice.

These modules come in a solid box. That makes me feel good. Actually, these modules are of high quality. We use them in a more complicated environment. There is nothing wrong with them. I trust FS a lot now. Definitely I will buy modules here again.

Functional. Just a tip. We deployed many FS QSFP+ modules which differed from the 25G SFP28 when installing. The label of the former needs to face down when inserting in to the port while that of the latter doesn’t.

Bought the industrial 25G modules for outdoor application. My Cisco switches could read their RX and TX powers.
