I placed an order for 2 MTP fibres and the respective cassettes, with their explanation, the connection was successfully connected. So it is important to ensure you have the appropriate cables to complement them.

After using these cassettes for the past few days, I want to tell you that these cassettes are a good choice for your data center application.

Compared to the products of other websites, I found that the price of FS is reasonable, and products look good, especially the whole website looks professional, so I did not hesitate to place the first order. It turned out that my judgment is correct. I bought 12pcs cassettes, each packed in a carton, and also each was equipped with instruction and test reports.

The updated cassette looks good. This time I not only bought the cassette but also purchased the enclosure and cables. Have to say that fs has all the products I need, I don't need to place orders on multiple websites, really convenient and saves time.

This is my second purchase. I had bought a 1U slide-out FHD enclosure and panels previously, and they worked well. So I bought a 4U FHD enclosure and 12 FHD cassettes several days ago. FS products are of good quality and cost-effective, and FS will be my long-term partner.

The FHD cassettes can be installed without tools for saving my time. The cassettes are of good quality as advertised, and I put them in my FHD enclosure.

I used to get stuck in the MPO/MTP polarity problems for a long time. This article helped out: http://www.fs.com/polarity-and-mpo-technology-in-40-100gbe-transmission-aid-475.html Guys have to be slightly careful on the polarity.

The only thing to specifically note is that you should get 1 cassette with polarity type "A" and one with polarity type "AF". The "AF" cassettes are like "rollover" termination of an RJ-45 connection. If you have 1x "A" and 1x "AF" cassette, then pin 1 on one end is pin 1 on the other end. If you have "A" and "A", then pin 1 on one end is pin 12 on the other end. It doesn't really matter much, but it's "cleaner" to use 1x "A" and 1x "AF".

We have installed all the FS.COM products recently purchased, all tested good. The cassettes are smaller than I expected, it saves space a lot and it matches with the 1RU rack I purchased very well. I am going to place another order this week, need to have some expansion. It seems that FS has a professional team for solution. I hope to get some technical support from them.

I received the shipments with thanks and confirm all items/qtys are correct.
