Cercis has manufactured Optical Loss Test Sets for customer  applications.  OLTS combine both sources and powermeter into one handheld instrument.  Two sources can be combined with two detectors to test duplex or multifiber connectors.

As shown at left, the graphic readout can display a set reference (-23.07 dBm for Cable 1 and -20.29 dBm for Cable 2), the wavlength of the source used, and the battery charge (92%).  Additionally, the contrast of the display can be adjusted to accommodated ambient lighting.
