Optical Power Meter by Optical Wavelength Laboratories

Note: Your Quotation Request will be directed to Optical Wavelength Laboratories.

The ZOOM 2 VFL from Optical Wavelength Laboratories is a high accuracy, high resolution, microprocessor controlled, optical power meter. It has a 65 dB dynamic range, and is calibrated at 850, 1300, 1310, 1490, and 1550 nm, making it ideal for both singlemode and multimode fibertesting, including Fiber To The Home (FTTH) PON networks. It is enclosed in a handheld case with a graphic liquid crystal display, and 2-key keypad for easy operation. The 2.5 mm universal fiber connector port allows connection to ST, SC, FC, and other popular 2.5 mm ferrule connectors, will operate for over 250 hours on a standard high-capacity 9 V battery, and has built-in auto shutdown. Reference values for each calibrated wavelength can be stored in permanent memory for quick and simple optical loss measurements.

It also contains a precision-coupled visual fault locator (VFL) optimized for fiber optics. An optical ball lens placed near the laser output focuses the light for optimum input into fiber optic cables, and special current-limiting electronics prevents laser burnout (a common problem with pen-style laser pointers), increasing the life of the VFL. The high-intensity red laser allows for fiber identification up to 5 kilometers away through both multimode and singlemode fibers. The device can also be used to check for faults within a few feet of its launch point. When the bright red light encounters a fault, the light is deflected into the jacket, producing a red glow at the point of the fault. The power meter measures 4.94 x 2.75 x 1.28 inches.
