OP712 USB Optical Power Meter
Standalone, Handheld, USB Optical Power Meter with detector and interface connector options

Click image to enlarge
The OP712 is a standalone USB Optical power meter that is operated and powered via USB. It can be integrated into the test and measurement process with any OptoTest Applications.
Absolute power and insertion loss (IL) are accurately measured with this USB power meter when used in conjunction with the corresponding software such as OPL-LOG and OPL-MAX. It is ideal for measuring fibers terminated with simplex connectors such as LC, SC or FC. When outfitted with a large area detector, the OP712 can also be used to test high density connectors such as MTP or MPO.
The LAAD series of adapters offer a quick-change magnetic interface and is available for all standard connector options.
Using the OPL-SDK, the user can write custom applications to control the OP712.
