With this equipment we can measure the light intensity from our switchers, media converters or signals from the pen optic. We can select what wave length usually 1310, 1550 or 1610 for GPON. Some monofiber equipments sends a signal TX using 1550 nm and the RX signal sends information in 1310 nm. Because of it, in some cases we can measure if there’s signal in fibers. With this equipment we can also generate signal to check connectivity in other points. Some equipments runs from +3dBm to -27dBm. Of course that’s depends on technology you’re using.
