INNO Instrument OLL-500-652D-SC-UPC OTDR Launch Fiber Reel 500 m Singlemode

INNO Instrument OLL-500-652D-SC-UPC OTDR Launch Fiber Reel

The INNO Instrument OLL-500-652D-SC-UPC is a 500-meter singlemode launch fiber reel designed for use with optical time domain reflectometers (OTDR). It introduces a controlled length of G.652D singlemode fiber between the OTDR and the fiber link under test, supporting measurement conditions used when evaluating connector events and fiber segments near the instrument interface.

Launch Fiber Configuration

• 500 m launch fiber length
• 9/125 µm singlemode fiber
• G.652D compliant fiber type
• SC/UPC connector interface on both ends
• Launch fiber assembly configured for OTDR testing workflows

Use in Optical Fiber Testing

Launch fibers are used during OTDR measurement procedures to introduce an initial fiber segment between the test instrument and the first connection event in a fiber link. This configuration allows the OTDR to settle after the launch pulse and supports observation of connector and splice events located near the beginning of the tested fiber span.

Typical Applications

• OTDR testing of installed fiber links
• Fiber network installation verification
• Connector and splice event evaluation
