This part of IEC 61290-4 applies to optical amplifiers (OAs) using active fibres (optical fibre amplifiers (OFAs)) containing rare-earth dopants including erbium-doped fibre amplifiers (EDFAs) and optically amplified elementary sub-systems. These amplifiers are commercially available and widely deployed in service provider networks.<\/p>\n

The object of document is to provide the general background for OFA transients and related parameters, and to describe a standard test method for accurate and reliable measurement of the following transient parameters:<\/p>\n

    \n
  1. \n

    channel addition or removal transient gain overshoot and transient net gain overshoot;<\/p>\n<\/li>\n

  2. \n

    channel addition or removal transient gain undershoot and transient net gain undershoot;<\/p>\n<\/li>\n

  3. \n

    channel addition or removal gain offset;<\/p>\n<\/li>\n

  4. \n

    channel addition or removal transient gain response time constant (settling time).<\/p>\n<\/li>\n<\/ol>\n
