OWL ZO2V ZOOM 2 (Zeroed Output Optical Meter) with VFL

The ZOOM 2 is a high accuracy, high resolution, microprocessor controlled optical power meter. It has a wide 65 dB dynamic range, and is calibrated to measure 850, 1300, 1310, and 1550nm, making it ideal for both singlemode and multimode fiber testing, as well as 1490nm for measurement of FTTx PON networks.

It has an attractive handheld case with an easy-to-read graphical liquid crystal display and 2-key keypad for easy operation. It is offered with a 2.5mm universal fiber connector for easy connection to ST, SC, and FC connectors, will operate for over 250 hours on a standard high-capacity 9v battery, and has built-in auto shutdown. The built-in charger port allows for wall power operation, as well as for charging 9- volt re-chargeable batteries.

The ZOOM 2 can store reference values for each wavelength to be used for optical loss measurements, and can display measurements in dBm, dB, and microwatts. The on-screen battery capacity indicator doubles as the battery charger display.

Other Features

• Simple 2-key operation
• Power measurements shown in dBm, dB, or microwatts
• Charger port allows for wall power operation or for charging 9-volt re-chargeable batteries

As an option, the charger port in ZOOM 2 optical power meters can be replaced by a precision-coupled Visual Fault Locator (VFL). By integrating a VFL into the power meter, troubleshooting for near-end faults can be done on the spot during testing.

OWL precision-coupled VFLs offer two distinct technological advantages over traditional laser pen-style visual fault locators.

First, a multi-million dollar micro-alignment machine is used to place a tiny ball lens between the laser diode and the output port, allowing for optimum precision-coupling of optical power into both multimode and singlemode fibers.

Second, red lasers are susceptible to burnout, which is typically caused by power surging from the battery when the unit is powered on, especially from new batteries. Over time, these battery surges can weaken the laser, significantly limiting the laser's effectiveness. OWL optical power meters contain special circuitry that protects the red laser diode from battery power surges, ensuring a stable and consistent source of red light as well as maximizing the life-span of the laser.
