3S Telecom Fiber Optic Launch Leads are designed for field technicians, fiber contractors and lab engineers who require accurate and reliable OTDR measurement results on fiber networks.

These specialized test cords resolve the OTDR deadzone limitation by adding a known fiber segment before the linkundertest. They minimize reflection interference and enable precise detection of nearend connectors, splices and faults that would otherwise be undetectable by direct OTDR connection.

Available in singlemode and multimode versions with various connector options and length grades, our launch leads guarantee highquality endface performance for field acceptance, troubleshooting and componentlevel lab testing. They serve as essential complementary accessories for our full range of OTDR testers.

Customization & HighGrade Options

Beyond standard specifications, 3S Telecom supports flexible custom-built launch leads to meet special field requirements. Customizable parameters include cable length, fiber type selection, and armored cable construction for harsh outdoor deployment. Premiumgrade Seiko connectors are available upon request to deliver superior connection stability and low-reflection performance for critical OTDR measurements.
