The variable attenuators are ideal for simulating cable loss for lab testing of link power margin or reducing power in links where receivers are being overloaded. Most Fotec variable attenuators are of the gap-loss type and mate to cables with the connector types listed. They work with either multimode or singlemode fibers. Many fiber optic equipment manufacturers use Fotec loopbacks and variable attenuators to help their customers install and troubleshoot their networks.
All Fotec attenuators are available at substantial discounts for quantity purchases.
