An OTDR, or optical time domain reflectometer, is used in fiber cable testing and analysis. OTDRs detect bends, faults, or distortions. These user-friendly devices can also measure the length of cables and form a picture, or trace, of the cable’s condition. Renting OTDRs has never been easier with ATEC’s wide array of options.
What Are OTDRs?
OTDRs are testing devices that troubleshoot fiber optic cables by sending pulses of high-powered laser light down the fiber to create traces. Then they measure the light that reflects back (referred to as backscattering) over time. A trace should be taken at first installation for immediate verification and future reference. OTDRs provide technicians with splice loss and reflectance. Capable of performing several tests as well as Tier 2 certification, OTDRs are ideal for an in-depth look at the fiber in question.
OTDR testers take their measurements with the use of backscattered light. Then they transmit pulses of light down the fiber, and the reflected light is analyzed. The pulse can be adjusted as needed, depending on the operator’s testing requirements. An OTDR fiber tester can measure the distance and loss between two points and make a variety of calculations.
What Is Tier 2 certification?
Fiber optic certification consists of two tiers: Tier 1 and Tier 2. Tier 1 certification is when an optical loss test, using an
OLTS, is performed on the cabling. This must be completed to proceed to Tier 2. Meanwhile, Tier 2 testing refers to the troubleshooting performed by OTDRs. During every stage of the fiber cable life cycle, troubleshooting is performed, which includes fusion splices and splice loss. OTDRs are valuable tools for fiber network maintenance, and these testers help operators check the quality of the fiber, connection, and splices.
How to use an OTDR
- Obtain the device and all the required parts needed for your test.
- Install the module to the main unit and remote.
- Turn both units on.
- Create a new project using the OTDR interface.
- Create an operator.
- Select a configuration for the test.
- Save and go to the home page.
- Set reference.
- Install necessary adaptors.
- Test.
