Many types of cleavers are used in today’s fiber applications — from simple “score and snap” types with carbide or ceramic blades to high-precision automated models with diamond blades. Determining which of them is best is ultimately dictated by the application and budget on hand.
Launch Cables, Part 2 discusses the practical use of launch and receive cables in specific testing situations with an OTDR. Part 1 (last month) dispelled some of the myths around launch cables, and explained the basic theory behind their use in testing the near end and far end connectors of…
Launch Cables, Part 1 offers a historical perspective on the need for and proper use of launch cables in OTDR testing. Part 2 (next month) will discuss specific testing situations.
By: Larry Johnson The optical time domain reflectometer (OTDR) is now thirty-six years old and aging gracefully. While fiber optic cables had been installed in North America since 1977, one major concern was and still is: how do we accurately locate a fault? This is the major reason that OTDRs…
One of the many reasons to use an OTDR for testing and troubleshooting is to get data about a severe bend or break in your cable plant. The OTDR can provide the location of a break so that you can send out a crew to repair it. But, how accurate…
The accepted best practice for testing link loss in a multimode network calls for the most accurate and repeatable test set up: the one-jumper reference method.
