KOLSOL AT338 NF-8508 Network Cable Tester LAN Optical Wire Meter Power Meter Tester
AT338 network tester is a multifuctional tool which can do POE test, fault location, non-contact voltage detecting, etc. It is a perfect tool for the work of network line engineering and telecommunication, computer, other metal conductor maintenance, etc.


Product Features:
Checks fiber faults by emitting red lasers and tests optical power and attenuation value of light.
Tests the faults of short circuit, open circuit, and cross in a LAN network.
Traces a cable with strong anti-interference ability.
Judges a cable by flashing the switch/router port where the target cable is being plugged in.
Tests CAT6 / CAT6 cables of lengths of 10m to 200m.
Checks the existence and standard of PSE(power sourcing equipment), either IEEE 802.3af or 802.3at, in your network.
Tests the quality of the crimping of crystal heads.
Product Functions:
1. Multi-Function Network Cable Tester
1) PoE testing : identify which pins are providing power and detect how much voltage, identify which the type of PSE (at/af standard)
2) Measure cable length accurately, the range is 200m.
3) Two scan modes selectable: AC filter & Non AC filter
4) Test physical status for STP, UTP lan cable.
5) Hub blink for locating network port by the flashing port light on Hub / Switch.



2.Optical Power Meter & Visual Fault Locator
1) Measurement of the power of optical sender (dBm and W).
2) Can measure 7 standard wavelengths,850/1300/1310/1490/1550/1625/1650,
3) Insertion loss test of optical devices
4) Locating the fault of fiber breakage, winding and so on.

3.Other Functions:
1) Quickly to check the RJ45 plug (crystal head).
2) Detect AC voltage presence (50V-1000V).
