- Introduction to the basic handling of measuring instruments, safety when working with LASER sources, and
connecting optical fibers. Work with inspection microscope (digital), problems of dirt distribution
within the connector connection, etc.
- Basic terms and definitions, sources of optical radiation, optical power meters.
overview of optical fiber standards according to ITU-T
measurement of optical power in burst mode and in standard mode (difference for PON networks), what
radiation sources are used (where F-P lasers, where DFB lasers, where SLED, where VCSEL)
Influence of macro and micro bends.
- Measurement of attenuation by the direct method (3 types - 1, 2, 3 patchcords)
measurement according to network and cable standards, wavelength
creation of a professional protocol.
- Measurement of attenuation by the method of two lengths, production of connectors, production of optical
fibers.
- Noise measurement, methods based on signal-to-noise ratio (OSNR) measurement
- Reflectometric measurements on single-mode routes - measurement of insertion and return attenuation,
route profile, OTDR measurements
measurement on the live network, measurement on fibers according to ITU-T (difference of measurement in
backbone and access network)
creation of a professional protocol
OTDR meter: basic parts of the instrument, dead zones of measurement, course of the backscatter curve
- Measurement of chromatic dispersion, methods of chromatic dispersion compensation
Design of chromatic dispersion compensator (majority of implementations are fiber), limit values for
backbone networks (penalties)
Spectral power characteristics of excitation LEDs and LD.
Problems of backbone networks - physical optical layers up to higher layers (MPLS, SDH). DWDM / CWDM.
Problems of optical access networks - all series of xPON technologies and their mutual compatibility
- Measurement of parameters of passive optical networks
passive network design
measurement by PON power meter
basic settings of PON networks (EPON, GPON)
