2. OFC Cable Types used in Telecom.
3. Connectors Types Used in OFC.
4. Types of Testing.
5. Equipments used for Testing.
6. Problems with today’s equipment.
7. Cost of equipment

3. 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.

4. 1. Single mode fiber patch cables
Use 9/125 micron SM cable & connectors
2. Multimode fiber patch cables
Use 62.5/125 micron or 50/125 micron bulk
MM cable & Connectors
3. 10gig multimode fiber optic patch cables
specially designed 50/125 micron fiber optimize
for 850nm VCSEL laser based 10Gig Ethernet.

5. 1. Simplex fiber optic patch cables
2.Duplex fiber optic patch cables
3.Ribbon fan-out cable assembly

6. 1. LC Connector

10. 1. End to End loss testing
2. Cable Commissioning
3. Splice and connector optimization
4. System ORL characterization
5. Dispersion verification and wavelength
measurements

11. a.
b.
c.
Both units must be
referenced with the
test jumpers
Confirm power
source is connected
to test fiber
Reading is only
accurate if both units
at same wavelength

12. a.
b.
c.
Tests the cable for damage
Double checks length and attenuation
And measures the polarization mode dispersion

14. 1. Jumper cable
2. Light source.
3. Power Meter.
4. Reflectometer.

15. There are two types of Reflectometer1. Optical Time Domain Reflectometer
- Measures reflectance and ORL
- Can characterize connectors and mechanical
splices
- Accuracy of plus/minus 2dB

16. 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

17. 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

18. 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.
