Page 4: Chapter 1 Introduction
Optical fibers coupled to these EVOAs should be single mode over the operating range of the EVOA (e.g. 780HP), and either FC/PC connectors (Item # EVOA800F) or FC/APC connectors (Item # EVOA800A) are accepted. The wavelength selector switch accesses calibrated settings for 785 nm and 852 nm, and also provides a position which the user can calibrate for any wavelength from 780 nm to 980 nm. -

Electronic Variable Optical Attenuators Chapter 4: Operating Instructions and Details • Item # EVOA800F has FC/PC connectors. • Item # EVOA800A has FC/APC connectors. The fiber patch cable and connectors should be cleaned whenever a connection is made. Note that the insertion loss when coupling these types of smaller core, single mode fibers can be well over 1 dB. -

Electronic Variable Optical Attenuators Chapter 5: Maintenance and Cleaning resolution (the leftmost digit has a maximum value of 1). The display range will auto-scale for low or high input power, and changes over at about 15 mW. The digital display also has a Low Battery warning that indicates when the battery needs to be charged. The warning appears while there is still sufficient charge remaining for the Li-ion battery not to degrade. - Page 16 The end faces of any fiber patch cables being connected to the EVOA should be cleaned every time a connection is made. Use, for example, Thorlabs’ FCC-7020 Fiber Connector Cleaner (sold separately). The end faces of the EVOA’s internal connectors can be easily damaged by dirty fiber ends, and if damage occurs, the unit will need to be returned to Thorlabs for repair.
