To reveal the insertion loss and reflectance of the near-end connection, the OTDR is connected to the link under test using a fibre ring launch cable. Also referred to as a pulse suppressor, the launch cable box aids in removing the blind area or dead zone caused by high launch power close to the fiber’s launch end when employing an optical time-domain reflectometer (OTDR). The launch box, which is frequently used with OTDR to reduce measurement uncertainty, is made to help test fibre optic cable.
When utilising OTDR to identify fibre optic cable faults, launch cable is an essential component. Both near-end and far-end connections can be measured with our premium fibre launch cable. All main fibre optic connector types (SC, LC, FC, ST, E2000) are compatible with the affordable fibre launch box, which comes with both single-mode and multimode cables.
