What is BS EN 61280-1-1 - Fibre optic communication subsystem basic test procedures about?
BS EN 61280 is a series on fibre optic communication subsystem basic test procedures. The fibre optic communication subsystem is a collection of individual telecommunications networks, transmission systems, relay stations, tributary stations, and terminal equipment usually capable of interconnection and interoperation to form an integrated whole. BS EN 61280-1-1 applies to fibre optic general communication subsystems. The object of BS EN 61280-1-1 is to measure the optical power coupled from the output of a transmitter under test into a single-mode optical fibre cable containing dispersion-unshifted fibre or dispersion-shifted fibre.
Who is BS EN 61280-1-1 - Fibre optic communication subsystem basic test procedures for?
BS EN 61280-1-1 on fibre optic communication subsystem is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 61280-1-1 - Fibre optic communication subsystem basic test procedures?
Fibre optic communication subsystem is any form of telecommunication that uses light as the transmission medium. BS EN 61280-1-1 defines the optical power meter that is capable of measuring the range of power at wavelengths provided by the transmitter. The optical power meter shall have a resolution of at least 0,1 dB. The meter has a detecting surface of sufficient size to capture all the power coming from the fibre that is put into it. The optical power is calibrated according to IEC 61315, the calibration report includes the correction factor, CF, defined as the numerical factor by which the uncorrected result of a measurement is multiplied to compensate for systematic error.
BS EN 61280-1-1 provides specifications on the Identification of test equipment used measurement uncertainty due to measurement inaccuracy and display resolution details of the fibre test cord and connectors, insertion loss repeatability of the connectors, including the worst-case random mated insertion loss, optical power meter uncertainties, names of test personnel, supply voltages and/or currents, rate and input signal characteristics, optical output measurement conditions: wavelength, transmitter mating connector model number, the warm-up time applied for temperature stabilization and extended operating conditions, if applicable. Using BS EN 61280-1-1 you can specify the fibre optic general communication subsystems.
