Sterlite Technologies Interview Questions, Process, and Tips for Experienced

1550 and 1310 wavelengths are both used in optical fiber communication, but have different properties.

• 1550 wavelength has lower attenuation and dispersion compared to 1310 wavelength

• 1550 wavelength is used for long-haul communication while 1310 wavelength is used for short-haul communication

• 1550 wavelength is less affected by fiber non-linearities compared to 1310 wavelength

• 1310 wavelength is cheaper to produce compare

Quality assurance is the process of ensuring that a product or service meets the desired level of quality.

• 7QC tools are used to identify and solve quality problems

• The tools include Pareto chart, cause-and-effect diagram, control chart, histogram, scatter diagram, flowchart, and check sheet

• QA involves creating and implementing processes and procedures to prevent defects and improve quality

• It also involves testing and ev...read more
