Tri-Star Design announced today they have successfully designed and developed a low-cost inline optical power monitor featuring a digital readout of the instantaneous power of a transmitted signal for EigenLight (Series 500). The Series 500 utilizes patented optical tap technology that maintains fiber continuity while measuring optical power. This allows for unrivalled performance among competing technology, including high directivity, low loss and low PDL. These features, in addition to the S500’s long battery life and intuitive user interface, make the Series 500 ideal for testing and monitoring the optical power of FTTX, Data Centers, Metro or Long Haul optical networks.
