I recommend this company to everyone, it's much better than expected, no matter its modules or services. Rachel, my consultant, is very helpful, and update me every steps in this purchasing process. When I received my Optical Transceiver Module I had ordered, it was well packaged and worked fine with my switch. If possible, I will buy all my fiber products in l-p.com.

I just placed my second order with LINK-PP and have been extremely impressed by the service. Orders are filled quickly and the prices are far better than ordering directly from local stores.
