Optical Fiber Identifier Available at GAO Tek
21st January, 2009

Toronto, Canada – GAO Tek Inc. offers an excellent optical fiber identifier (GAO 820), which is specifically designed for engineers and technicians to identify dark or live fiber and identify excessive losses due to misalignment of mechanical splices or poor connections. This optimized device can also be used to display transmission direction, identify multiple signal frequency (270Hz, 1KHz, 2KHz) and detect bare fibers, close packed fiber and pigtails.
GAO820 optical fiber identifier uses safe and reliable macro bending technology to avoid the disruption of network communications on account of the need to discount or cut the fiber optic cable for identification and testing. With a very small signal loss, normal communications can be maintained while the GAO 820 identifies the transmission direction, speed and relative signal strength on its 5-level display.

GAO 820 Optical Fiber Identifier provides the following features:
• 5-stage display of signal intensity
• Detachable detector
• Low-voltage indication
• Automatic shutdown
• Rechargeable lithium battery
• Portable and simple to use
Specifications of GAO’s Optical Fiber Identifier:
• Available wavelength range 800nm to 1700nm (1550nm wavelength calibration)
• Identification of signal type: CW, 270Hz ±5%, 1KHz ±5%, 2KHz ±5%
• Detector: InGaAs (photosensitive surface 1mm, 2PCS)

• Communication signal indications: direction indicator + frequency indicator + intermittent beep tone + strength indicator light
• Comparison light indication: direction + frequency + intermittent beep tone + strength indicator light
• Signal intensity indication: 5 LED display
• Continuous working time:> 4 hours
• Dimensions: 160mm * 35mm * 30mm
