ALPSAT Multifunctional RJ45 Network Cable and Fiber Optic Cable Tester
ALPSAT AS324 is a professional testing and measuring device for technical personnel providing installation and maintenance services for security monitoring systems, communication cables, network cabling, and fiber optic cables.

It tests the continuity and classification of network cables ; performs critical checks on RJ45 components and has a cable tracer function. also includes PING testing , IP address scanning , port flashing , standard and non-standard PoE equipment details , and PoE power online test functions. In addition, it features an Optical Power Meter (OPM) and a Visual Fault Detection Device (VFL) for the installation and maintenance of fiber optic cabling systems.
SPECIFICATIONS
- Main unit and cable tracker :
4-inch color IPS touchscreen , 800×480 resolution.
Both the main unit and the cable monitor have built-in foldable batteries . - Network cable continuity test :
RJ45 connector encryption check and network cable length testing are integrated into a single device. - Cable tracing and UTP cable testing :
Prevents false positives by simultaneously and accurately identifying cables. - Inductive NCV scanning function :
AC 12–1000V, 50/60Hz. Dual audible and visual alarm. Separates phase (live) and neutral (neutral) lines. - RJ45 TDR cable testing :
Detects breaks and short circuits in network cables, and measures attenuation, reflection, delay difference (skew), etc. - Cable length test :
Maximum measured length 3000 meters (9842 ft).
Note: Only open circuit (open) cable tests are valid. - PoE detector : Supports
IEEE 802.3af/at/bt (Hi-PoE/PoE++) and non-standard PoE protocols.
Detects power supply mode and powered line pairs. - FTP function :
Test logs and data can be copied over the network via FTP . - 1000 Mbps RJ45 network port :
Includes network tests such as ping testing, IP address conflict detection, PPPoE dial-up ,
route tracing (traceroute) , and LLDP/CDP switch port details . - Optical power meter (OPM) and visual fault detection device (VFL) :
Emits a red laser to detect fiber optic line breaks, cracks, formations, and other faults. Detects
power at wavelengths of 850/980/1270/1300/1310/1490/1550/1577/1625/1650nm.
