Frequently Asked Questions
What is the purpose of an OTDR Fiber Ring?
It acts as a launch or receive cable to bridge the OTDR dead zone, allowing the instrument to measure the insertion loss and reflectance of the first and last connectors in a link.
Is this suitable for multimode fiber testing?
No, this unit is specifically configured for single mode (SMF) applications.
Can I use this for long-haul testing?
This 150m length is optimized for premise network testing; for long-haul applications, longer launch boxes are typically required.
Are the connectors field-replaceable?
The fiber is contained within the ruggedized ring; consult the datasheet for maintenance recommendations.
What is the fiber type used?
This unit uses standard G.652 single mode fiber.
