Koleksi: OTDR Launch Cable box

The OTDR Launch Cable Box, connects the OTDR to the link-under-test, discloses the insertion loss and reflectance of the near-end connection. The Launch Box creates the proper conditions for testing another similar optical fiber for faults. This method avoids undesirable variations in loss and distance measurements. A launch fiber helps to overcome the blind spot or ‘Dead Zone’ of an OTDR brought about by high launch power or faults near the launch end of the fiber.
