I needed quite a few AOC cables, 40G optics and other miscellaneous items for data center system and the Fiberstore had everything that I needed at the lowest price. I spent quite a bit of time searching the web for the items that I needed and CCS offered the best value with a combination of price and quality. Shipping was reasonable and fast. I have additional needs and I will certainly use them again.

I found the website, I ordered, I paid, it came, I installed, I'm happy. A fraction of the cost of others. Will be buying here from now on.
