1. To Ensure the fiber is Properly working.

2. To Check IL and reflectance of all splices and connections.

3. To calculate the cable losses.

4. To find out the fault location for repair.

1. Single mode fiber patch cablesUse 9/125 micron SM cable & connectors2. Multimode fiber patch cablesUse 62.5/125 micron or 50/125 micron bulk MM cable & Connectors3. 10gig multimode fiber optic patch

measurements

a. Both units must be referenced with the test jumpers

b. Confirm power source is connected to test fiber

c. Reading is only accurate if both units at same wavelength

a. Tests the cable for damage b. Double checks length and attenuationc. And measures the polarization mode

dispersion

a. Do to glass air interface

b. Rayleigh backscattering

c. Pr = Reflected Power

d. Pi = Incident Power

1. Jumper cable2. Light source.3. Power Meter.4. Reflectometer.

There are two types of Reflectometer-1. Optical Time Domain Reflectometer

- Measures reflectance and ORL

- Can characterize connectors and mechanical splices

- Accuracy of plus/minus 2dB

2. Optical Continuous Wave Reflectometer - Also measures reflectance and ORL

- Some units measure bi-directional loss

- Accuracy of plus/minus 0.4 dB to 1.0 dB

2. Optical Continuous Wave Reflectometer - Also measures reflectance and ORL

- Some units measure bi-directional loss

- Accuracy of plus/minus 0.4 dB to 1.0 dB

1.Light source and power meter must be referenced at the same point.

2.Wavelength of light source and power meter must be the same.

3.Jumpers to test equipment can wear down.
