Handheld Visible Laser Source

Monday, June 27th, 2011

Toronto, Canada – GAO Instruments has launched its handheld visible laser source. It is used to find fiber faults and is suitable for both single mode and multi mode fiber. The laser source is an ideal instrument for the installation and maintenance of optical networks.

This handheld visible laser source, model GAO A0870004, features low voltage warning, auto power-off, simple button operation and an energy-saving design. It uses visible red light to indicate the location of fiber faults from a macro bend point, break, problem coupler or connector or a mechanical splice that is not well aligned. It can distinguish the faults in fiber jumpers, jumper boards, distribution frames and tie-ins. Its working wavelength is 650 nm ± 20 nm. It offers FC, ST and SC adaptors. CW and 2 Hz alternative optical output modes are also available. This laser source overcomes the usual limitation of the dead zone of an OTDR to accurately detect fiber fault positions. In addition, it is powered by a 9 V/160 mAh NI-MH rechargeable battery which provides continuous operation of 8 to 10 hours.

This handheld visible laser source belongs to GAO’s family of Visual Fault Series. This line of products also includes a wide variety of visual fault locators such as Optical Visual Fault Locator, Pen-Type Visual Fault Locator and Rugged Visual Fault Locator which is widely used for fiber optic network maintenance in telecommunications and CATV systems.

Portable Optical Power Meter

Monday, June 20th, 2011

Toronto, Canada – GAO Instruments has launched its portable optical power meter which is a single-chip microprocessor controlled intelligent optical power meter. The portable optical power meter offers simple and reliable operation and is suitable for various environments. It is commonly deployed in the construction and maintenance of fiber optic communication systems and fiber optic CATV and is used to test continuous optical signals.

This portable optical power meter, model A0850008, features self-calibration, low voltage warning, auto-off function and real-time data monitoring function. It is equipped with a built-in long wavelength camera probe. It operates over the wavelength range of 850 to 1700 nm and offers working wavelengths including 850 nm, 980 nm, 1300 nm, 1310 nm, 1490 nm, 1550 nm and 1625 nm. The meter performs power measurements within a test range of -70 to10 dBm and -50 to 26 dBm at an accuracy of ± 5%. It identifies frequencies of 270 Hz, 1 kHz, and 2 kHz automatically. It also boasts automatic reset and automatic range switching. Optical interfaces including FC, ST and SC are provided for selection. It has a large memory capacity of up to 1000 groups of data and uses an RS232 interface to upload data to a computer for further analysis.

This optical power meter belongs to GAO’s family of Power Meters. This line of power meters includes Fiber Optic Power Meter/Light Source, Handheld Optical Power Meter and other similar products. This line of products is very popular for CATV technicians and engineers.

TDR Cable Fault Locator

Tuesday, June 7th, 2011

Toronto, Canada – GAO Instruments has launched its TDR cable fault locator which is intended to automatically locate and indicate the distance to many kinds of RF cable faults such as short circuits, open circuits or high resistance points. It is widely used in testing underground cables to find impedance break points and locate and reveal cable damage, tie-in dampness and terminal impedance failure in HFC systems.

This high-performance cable fault locator, model A0N00019, has a double cursor display to analyze test results. It tests cables of 25, 50, 75 and 100 ohm impedance over a long measurement range of 15 to 2000 m at accuracy of ±1 m ± 1%. This cable fault locator also provides an intuitive electronic map relevant to the time domain picture allowing the fault to be detected easily. Its 7.2 V 1.8 AH NI-MH battery allows for average 7 to 8 hours continuous operation on full charge. In addition, it can be connected to a computer for file upload and data analysis.

This high-performance cable fault locator belongs to GAO’s family of CATV Meters & Instruments. This line of products includes CATV analyzers, digital signal level meters, PCM channel analyzers, handheld signal level analyzers and QAM analyzers which are widely used for CATV signal testing and are intended for analog and digital television network construction and maintenance.

Wednesday, June 1st, 2011

Toronto, Canada – GAO Instruments has launched its handheld signal level meter which is a portable and easy-to-use instrument with many functions. This high-performance signal level meter is specially designed and manufactured for CATV system installation and testing.

The signal level meter, model A0500013, operates over a frequency range of 46 to 870 MHz. It tests CATV signal levels in both channel and frequency modes. It also measures CATV TILT, C/N and trunk cable voltage parameters with high efficiency and accuracy. The meter scans 125 channels at the same time and has the ability to display 2 channels simultaneously. It provides a resolution bandwidth of 280 kHz ± 50 kHz and a level range of 30 to120 dBμV with an accuracy of ±1.5 dBµV at room temperature. The portable signal level meter offers a quick response time without requiring warm-up. In addition, it can be powered by both a DC 7.2 V/1.4 Ah rechargeable battery and AC 110/60 Hz to 220 V/50 Hz (±10%) and operates continuously for more than 5 hours on a single charge.
