DVT – Divot™ Bare Fiber Adapter /Testing Device
Quickly connect test equipment to bare fiber.
Spend your time testing, not connecting. Quickly connect test equipment to bare fiber. System utilizes replaceable index matching gel cartridges resulting in quick low loss and low reflectance connections to your OTDR or other test systems.
Connect the patch cable included with the system to your test equipment and insert bare fiber into the end of the Divot™ module. Simply strip and clean a few inches of fiber down to 125uM cladding, leaving approximately 3/4” of bare fiber exposed. Insert the bare fiber into the Divot module until it stops. The device will accept a non-cleaved fiber with a typical insertion loss of less than 0.8dB. Cleaved fiber will result in even lower insertion loss. Connections are suitable for many testing applications with results similar to a standard terminated piece of fiber.
How it works
The bare fiber when inserted into the Divot™ Module, goes through a cartridge which is filled with an optical coupling compound. The compound is applied to the end of the fiber as it passes through the cartridge, then enters into a custom ferrule which has a small divot on the end. The divot creates a small cavity at the end of the ferrule which retains the optical coupling compound from the inserted bare fiber end. The bare fiber is then mated to a precisely aligned ferrule on the patch cable resulting in a quick, low loss connection suitable for most testing applications.
Replaceable Cartridges
The Divot™ Module can be easily disassembled in order to replace the internal cartridge. Every insertion of bare fiber will use a small amount of coupling compound from the cartridge. A cartridge will typically yield a minimum of 500 insertions.
Maintenance
The Divot™ Module can be easily disassembled for cleaning or maintenance. Occasionally you may have to clean the ferrule on the patch cable and the ferrule in the Divot Module. The Divot ferrule assembly can be totally removed from the housing and cleaned or immersed in alcohol.
