If you’re responsible for Layer 1, shouldn’t you control all of Layer 1? We think so, and we understand through years of TEK Center testing that the transceiver can have a tremendous effect on your Layer 1 performance. When you source your transceivers from a trusted Layer 1 partner like Berk-Tek, you Own the Link. And when you pair Berk-Tek’s premium transceivers with our GIGAlite™-10XB glass, you will See the Difference when you need longer reach and/or more connections than the standards allow…GUARANTEED. Berk-Tek transceivers are backed by not only our five-year warranty, but also by the company that’s been working to earn your trust since 1961.
