Using a new, patented process, OZ Optics, as part of its new series of inline optical power monitors and tap couplers, now offers a digital inline optical power monitor (for more details about OEM optical power monitors, see the "Inline Optical Taps and Monitors" data sheet). Based on a groundbreaking new fabrication process, these all-fiber taps and monitors provide a way to easily measure the average signal intensity through an optical fiber via tapped light channeled into a built-in photodiode, without interrupting the traffic. The photodiode produces a signal proportional to the optical power traveling through the fiber with high directivity. The OPM-200 product integrates a novel inline optical tap with a low noise InGaAs detector in combination with a high dynamic range logarithmic amplifier. The built-in microcontroller processes and displays the power transmitted through the selected fiber channel on an LCD display. The optical tap modules and display units are independently calibrated, so any display unit can be plugged into any tap module and the measured power will be automatically calibrated. A low voltage circuitry design ensures a long lifetime for the built-in battery. The detector module can be calibrated for either a single wavelength or for a broad wavelength range. Optional, RS-232 and analog outputs are also available. The OPM-200 is ideal for network monitoring, out of specification alarms, and/or DWDM systems for real time monitoring and feedback. Our inline taps are highly directional and ideal for monitoring traffic traveling in one direction only. It may also be used for measuring return losses instead of transmitted power. In the same product family, OZ Optics now provides OEM single channel optical power monitors and multi-channel power monitors for DWDM system integration.Features• Low insertion loss• Continuous fiber.
