An OTDR launch cable, which connects the OTDR to the link-under-test, discloses the insertion loss and reflectance of the near-end connection. It is often available on a small spool or within a “launch box”, which is used to create the proper conditions for testing another similar optical fiber for faults. This method avoids undesirable variations in loss and distance measurements. A launch fiber will help 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.

FVFL-204 Pen Shape Visual Fault Locator is a compact but powerful fiber optical cable test tool, with an output power up to 1mW, which can be used to locate sharp bends & breaks in jacket or bare fiber within 5km. It can also be applied to identify the connectors in patch panels and identify the fibers during splicing operation. The choice of a continuous wave output mode for steady fault illumination or a flashing output mode makes for easier fault location. Please note: Due to import restrictions on lasers, shipments will only be arranged for countries that allow imports.
