"I would not recommend Umlink.com. I do many fiber optic jobs a year and thought i would give UMlink.com a try. Do yourself a service and choose a more reputable vendor. No one answers the phone for Umlink.com nor does Umlink.com returns voice mails. I have been trying to exchange material and I have yet to receive a response from Umlink.com. When spending the money on fiber equipment pick a company that will talk with you and make sure you get the right material. Umlink.com is not a company to have an ongoing vendor-dealer business relationship. "
