I have used them a couple of times, they are quick and easy to use.

I have had only one bad experience with the GLC-EX-SM1550-40 transceiver bought from FS.COM—slow delivery. I told them about it and got IMMEDIATE satisfaction. The reason is because they were on holiday to celebrate the new year! Great place to do business.

I have installed the 1G SFP EX transceiver to Cisco SFE2010P switch and Blackbox LIG1014 switch, it works good. The shipment is fast, and the customer service is very attractive. Great Service, Great Product!

Ordering process was great and the Cisco GLC-EX-SM1550-40 optics delivered very fasy. As the replacement for Cisco SFP, works fine on our switches, which convinced me these optics have been tested definitely. The company deserves five stars!!

Quick, easy, great information, kind customer service rep. who knew all the answers right away. Fiberstore does a great job of providing excellent service! Will recommend FS to our clients and I will buy here again.

Have dealt with Fiberstore for many years and their service and products are always reliable and excellent.They always provide great customer service, knowledgeable folks on chat lines. Always love shopping from Fiberstore. Fantastic Online Store.
