Compact Fiber Optic Identifier with a Detachable InGaAs Detector

This compact fiber optic identifier provides transmission direction, multiple signal frequency identification and a detachable InGaAs detector.

Online PR News – 30-January-2013 – Toronto/Ontario – Toronto, Canada - GAO Instruments ( recommends its compact fiber optic identifier which provides transmission direction, multiple signal frequency identification and a detachable InGaAs detector. It is intended for engineers and technicians to identify dark or live fiber and excessive losses due to misalignment of mechanical splices or poor connections.

This compact fiber optic identifier, model C0230001, employs safe and reliable macro bending technology to avoid the disruption of network communications that would normally be caused due to the need to disconnect or cut the fiber optic cable for identification and testing. With a very small signal loss, normal communications can be maintained while identifying the transmission direction, speed and relative signal strength on its 5-level display.

This portable and simple to use fiber optic identifier offers a wavelength range of 800 to 1700 nm. It identifies signal frequencies of CW, 270 Hz, 1 kHz, and 2 kHz. The identifier is compatible with multiple adapters including Φ250 µm bare fiber, Φ900 µm tight tube fiber and Φ3 mm pigtail fiber. It provides communication signal indications, comparison light indication and has 5 LED for signal intensity indication. The identifier has a low-voltage indicator and an automatic shutdown function when not in use. Its rechargeable lithium battery allows for more than 4 hours of continuous operation.

This compact fiber optic identifier belongs to GAO's family of Optical Fiber Identifiers. Another similar product in this line is Portable Optical Fiber Identifier which features core power display of the fibers, low bending loss and highly efficient output and serves as an essential tool in the installation and maintenance of telecommunication and CATV systems and other fiber networks. The two handheld identifiers are simple, rugged, easy-to-use test instruments to detect the presence of network traffic, test tones and multiple signals and determine the direction of signal flow.
