Cable testing services are offered to ensure the safety, reliability, and performance of cables.
These services include testing for various parameters.
Copper Cable Testing
- Insertion Loss (IL): Measures signal attenuation as it travels through the cable.
- Near End Crosstalk (NEXT): Measures the amount of signal leakage from one twisted pair to another within the same link.
- Power Sum Near End Crosstalk (PSNEXT): Measures the combined crosstalk from all twisted pairs in a cable to a specific pair at the near end.
- Attenuation to Crosstalk Ratio (ACR): Measures the signal attenuation relative to the amount of crosstalk.
- Far End Crosstalk (FEXT): Measures the signal leakage from one twisted pair to another at the far end of the cable.
- Alien Crosstalk: Measures the amount of signal leakage from other cables in the vicinity to a specific pair.
- Power Sum Alien NEXT (PSANEXT): Measures the combined crosstalk from all other cables to a specific pair at the near end.
- Power Sum Attenuation to Crosstalk Ratio – Far End (PSAACR-F): Measures the signal attenuation relative to the combined crosstalk from other cables at the far end.
- Alien Crosstalk Margin Calculation (ACMC): Measures the combined margin for both PSANEXT and PSAACR-F
Optic Fibre Testing
Optical fibre testing involves several key parameters to ensure reliable data transmission. Testing verifies that the fibre optic cable and its components meet the required performance specifications
- Insertion Loss: This measures the total signal loss across a fibre optic link.
- Return Loss: This parameter measures the amount of light reflected back into the source at connections and splices.
- Optical Power: This refers to the intensity of the light signal traveling through the fibre.
- Bandwidth: This refers to the amount of data that can be transmitted through the fibre optic cable within a given time frame.
- Wavelength: This refers to the specific wavelength of light used for data transmission.
- Dispersion: This refers to the broadening of optical pulses as they travel through the fibre.
- OTDR Testing: Optical Time Domain Reflectometry (OTDR) is a powerful tool used to measure the loss and distance to faults along a fibre optic cable.
- Continuity Testing: This verifies that the fibre optic cable is intact and that the signal can pass through the entire length of the cable without interruption.
