AHH1 Fiber tracer     The AHH1 is an essential installation and maintenance instrument by inserting fiber into its adapter head, it can identify SM optical fibers without any damage by detecting the optical signals being transmitted through them so that avoid to opening the fiber at the splice point for identification and interrupting the service. The AAH1 also allows relative core power display and identifies the 270Hz, 1kHz and 2kHz frequency. When they are used to detect the frequency, the continuously audible tone could be heard. There are four types of adapter heads available: Ø0.25, Ø0.9, Ø2.0 and Ø3.0.   Features   AHH1 Features: l Wonderful streamline appearance. l Multi adapter, easy replace. l Test bare fiber, tight tube optical fiber, optical fiber jumper. l Identify CW and modulated light 270HZ, 1KHZ, 2KHZ.   AHH1 Package Contents: 1 AHH1 Fiber tracer 1 Adaptor Heads (4pcs.) 1 Portable Bag   AHH1 Options: l AHH4 Certification calibration AAH1   Specifications   Optical Power Reading -40 to+5dBm Signal Frequency 270Hz, 1kHz, 2kHz Identification wave length range 800～1700nm Sensitivity -28dBm (@1550nm, bare fiber) Identification signal type CW, 270Hz±5%, 1KHz±5%, 2KHz±5% Continuous working time ＞4 hours Insert loss (1550nm) Ф250μm: 1.0dB Ф900μm: 0.5dB Ф3mm: 0.5dB Detector model InGaAs Detector type Ф250μm bare fiber Ф900μm jacketed fiber Ф3mm trail fiber Communication signal indicator direction indicator light + noncontinuous buzzing + signal strength indicator light Contrast light signal indicator direction indicator light + frequency indicator light + continuous buzzing + signal strength indicator light Signal direction Left & Right LED indicator Power Supply 2pcs.1.5V AAA batteries Operating Temperature -10－+50°C Storage Temperature -20－+70°C Weight 210 grams Qualified CE, RoHS and WEEE
