Range Statement

Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. It is restricted to essential operating conditions and any other variables essential to the work environment.

Type of optical measurement must include:

detecting the presence of an active optical network terminal (ONT)

determining absolute optical power (in dBm)

determining insertion loss (in dB)

determining relative optical power level (in dB)

Instruments must include:

hand-held optical power meter

hand-held optical source

handheld optical fibre identifier (OFI-FTTx)

active optical network termination (ONT) detector

optical loss test set (OLTS)

passive optical network (PON) meter
