1250 to 1620 nm; Tap Ratio 1%; Return Loss 70 dB; Dynamic Range -32-+20 dBm; Directivity 35 dB; Fiber Type SM, PM; Connector FC/UPC As part of its series of inline optical power monitors and tap couplers, OZ Optics offers the OPM-200, a digital inline optical power monitor. Based on a groundbreaking, patented 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 power monitor 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 inline power monitor is ideal for network monitoring, out of specification alarms, and/or DWDM systems for real time monitoring and feedback. OZ Optics’ inline taps are highly directional and ideal for monitoring traffic traveling in one direction only. They 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 can offer multi-channel power monitors for DWDM system integration on demand.

Littman-Metcalf Configuration; Center Wavelength 1310 to 1330 nm; Wavelength Span >100 nm; Energy ≥17 mW; Coherence Length >7 mm NTT Advanced Technology’s 200 kHz swept light source for OCT imaging is currently the highest speed swept-wavelength light source in the world. Emitting wavelengths in the 1.3 μm band, the swept light source is ideally suited for OCT-based examination of the coronary arteries. The device accelerates image acquisition and as a result reduces diagnosis time. This reduction in diagnosis time contributes to a great reduction of both the physical and the psychological impact on patients. The total system cost can be reduced because the load on the image processing system is reduced and the linear frequency sweeping enables easy calculation of the relationship between time and wavelength. The swept-wavelength light source with a KTN deflector is aiming at the usage in phase sensitive OCT systems (Doppler OCT and PS OCT: applications to new OCT diagnosis methods) because of its lower jitter than that of the more generally used MEMS-based light sources. Core building block of the wavelength swept light source is a laser with an external resonator, the so-called Littman-Metcalf configuration. By optimizing the laser with a highly efficient diffraction grating and KTN light deflectors into a compact structure, high-speed operation, a wider wavelength sweep span, and sufficient coherence length are realized. Key Features: High Speed (200 kHz Sweep Rate) Voltage-controlled Sweeping Formats (k-linear scan available) High Phase Stability (Low Trigger Jitter <78 ps) Coherence Length 7 mm at 200 kHz Scan High Reliability (No Moving Parts) Wavelength Sweep Span >100 nm Average Light Output ≥17 mW Applications: OCT Imaging
