Network cable toner and probe provides clear and precise tracing of communication cabling, tests RJ11and RJ45 terminated cables for mis-wires, open and short faults, locates cables safely and effectively at patch panels, switches, termination blocks or hidden within bundles.
Ethernet cable/phone line toner and tester provides you tone and trace Cat5 Cat5e Cat6 cable or telephone line effectively, RJ11 RJ45 cable sequence collation, continuity test, DC positive negative polarity detection.
Basic butt set is great for the occasional testing the phone lines of alarm systems, fax lines, elevator or other emergency lines, test tone on faxes and panels as needed, or used as a temporary communication handset (no speakerphone).
Basic telephone test set comes with alligator clamp and a 66 block tip as well as a coupler, so it can offers three ways to connect to the line. The small telephone has the functions including FSK/DTMF dual system caller ID (only the number), dial tone, dial out, on off hang up, redial the last number.

10KM aluminum alloy visual fault locator fiber optic cable tester meter for CATV test,Universally connector for test different ST,SC,FC interfaces.
Handheld fiber optical power meter FC ,SC cable tester,Wavelength range: 800~1700,Power measurement range: -70~+10.

Fiber Optic Cable Tester: It can measure 850/980/1300/1310/1490/1550/1625nm and other 7 wavelength of the optical absolute power, test range:-70dBm~+10dBm..
Linear and non-linear with same display screen,alternatively steady / strobe red light source.
work for 40 hours with automatic shutdown..
Visual Fault Locator: 2.5mm Universal Connector the connector of the detector is compatibly designed for ST, SC, FC interferes both in circle and square shape of different fiber optic cables..
It can easily and accurately detect and locate fiber breaks, poor connections, bending or cracking. The detector will emit a 650nm bright red light for fiber tracing, breaks or faults in the fiber will refract the light, creating a bright glow around the faulty area..
