Q: Do the fast photodiode detectors (FPD & FPS-1) have attenuators and fiber adapters available for them?
A: Yes, there are a variety of accessories such as attenuators and fiber adapters available for the FPD & FPS-1 Fast Photodiode Detectors. Fast Photodiode Detectors are used for displaying temporal pulse shape on an oscilloscope. Please note that in order to mount these accessories to the FPS-1 you will need the SM1-to-M20 adapter 1G02259. This is mentioned in the catalog spec page but is sometimes missed. No adapter is needed for FPD models.

Q: When using the fiber optic adaptor, how do we handle power loss due to the fiber relative to calibration?
A: All Ophir power meters, including photodiode power meters, have an air gap between the fiber tip and the sensor. Therefore they measure the power emitted by the fiber into the air and do not take into account any reflection losses there are in the fiber. Therefore, if in actual use, the fiber will be coupled with no loss to another element, then the losses should be added to the reading. These losses are usually about 4%. Thus if the reading on the Ophir meter says 100mW, then in lossless use, the real power will be 104mW.

Q: Can the PD300 be used with the filter in and with fiber adapter at the same time?
A: Yes, the adapter is arranged so the user can use it either with filter out or in.

Q: To connect a fiber to an Ophir sensor, why do I need 2 items – an “Adapter” and a “Mounting Bracket”?
A: The idea is used with most (though not all) sensors; the fiber optic connectors are standard (such as FC, SMA, etc.), but the sensors are all different in their mechanics, so we use the standard FO connectors but provide in addition mounting brackets for connecting the FO connectors to the various sensors.
