TM570 Fiber Optic Tester 3-in-1 — Optical Power Meter -70~+10 dBm, VFL Visual Fault Locator & RJ45 Cable Tester, Rechargeable Li-ion, FC/SC/ST, Compact 130g Fiber Light Meter

About this item

• 3-IN-1 FIBER OPTIC FIELD TESTER — OPM + VFL + RJ45 IN ONE COMPACT DEVICE — TM570 combines Optical Power Meter (-70 to +10 dBm, 10 wavelengths 800-1700nm), Visual Fault Locator (bright red light, 10-15km range), and RJ45 network cable continuity tester — eliminating three separate tools from your kit. At 130g with rechargeable Li-ion battery, TM570 is designed for fiber technicians who need a complete measurement kit in one pocket-sized device.
• HIGH ACCURACY OPTICAL POWER METER — 10 WAVELENGTHS 800-1700nm — Measures optical signal power from -70 to +10 dBm with ±0.2 dB accuracy across 10 wavelengths (800/850/980/1300/1310/1490/1550/1625/1650/1700nm) — the widest wavelength range in QIIRUN's OPM line, covering GPON (1310/1490/1550nm), XGS-PON, and legacy multimode (850/1300nm) networks. Universal 2.5mm interface accepts FC, SC, and ST connectors.
• BRIGHT RED VISUAL FAULT LOCATOR — FIND FIBER BREAKS & BENDS INSTANTLY — Built-in VFL emits high-power red light (650nm) visible through fiber jacket, enabling fast identification of breaks, macro-bends, bad splices, and dirty connectors without disconnecting active fibers. Continuous and flash modes for different fault-finding scenarios. Compatible with APC and UPC connector types via FC/SC/ST interfaces.
• RECHARGEABLE Li-ion BATTERY + AUTO POWER-OFF — NO BATTERY REPLACEMENT COST — Built-in rechargeable Li-ion battery charges via USB — no AA/AAA battery purchases needed in the field. Auto power-off (10 minutes) prevents accidental drain. Backlit LCD display for low-light cabinet and underground vault work. Wavelength memory function retains last-used wavelength setting between power cycles. Compact design with LED flash lighting for work in dark enclosures.
• COMPLETE FIBER FIELD KIT FOR FTTH INSTALLERS & NETWORK TECHNICIANS — TM570 handles optical power measurement, VFL fault location, and RJ45 cable continuity testing for FTTH/FTTB/CATV and enterprise network maintenance. Pairs with QIIRUN AI-9, SD-9 and all major fusion splicers. RJ45 tester verifies cable wiring continuity up to 300m for CAT5/CAT5e/CAT6.
