    Combining live fiber detection and dark fiber
pinpointing in one cost-efficient test tool
Induces minimal loss: ≤1 dB
Fail-safe detection and results
Detects if a fiber is active or not prior to maintenance
Locates a particular dark fiber using tone recognition
(270 Hz, 1 kHz, 2 kHz)
Identifies traffic direction on a live fiber
Displays the power transmitted through the fiber
Three times faster test time     In-Line Power Measurement
As stated, the LFD-250B controls the insertion loss within the fiber (IL) in dB. But the absolute value of the measured signal is in dBm,
so knowing the loss in dB and the power level of this light exiting, power can be measured with a better accuracy than traditional
fixed loss LFDs. Of course, coupling efficiency is a factor (3 mm jackets absorb more than 1.6 mm and 900 µm jackets). However,
since loss is monitored as a basis for motor positioning, the unit knows what size of jacket is being tested (either 900 µm, 1.6 mm
or 3 mm), so the LFD-250B automatically uses the proper coupling efficiency parameter and computes the power within any fiber,
at any wavelength, with 1 dB repeatability.             Packaging & Shipping   Payment terms T/T,Western union,Money Gram,LC.T/T in advance.   Contact information Tel:0086-755-36934393 Fax: 0086-755-33503470 Mobile:0086-13823128817 Skype:kitty.hsv    www.hontek.net for more information!
