The Pro'sKit MT-7616 is the long-reach version of Pro'sKit's 4-in-1 fiber optical power meter. It carries the same 8-wavelength InGaAs power meter, RJ45 LAN cable tester and LED work light as the MT-7615, but doubles the visual fault locator to 30 mW — enough red-laser energy to push a visible break indication 14–16 km down a single-mode span instead of 10–12 km.
That extra reach is what backbone and long-haul FTTH crews pay for: one technician can locate a break or a bad splice on a long feeder without driving to the far end. Optical power reads from -70 dBm to +10 dBm at 0.01 dB resolution in dB, dBm, nW, uW or mW, with Wave ID, REF measurement, self-calibration and 500 groups of storage, all running over 50 hours on a Micro-USB rechargeable lithium battery.
Key Features
- 30 mW visual fault locator ⚡ — 650 nm red laser reaches 14–16 km on single-mode fiber, twice the span of the 15 mW MT-7615
- 4 tools in one 🔧 — optical power meter, VFL, RJ45 LAN cable tester and LED flashlight in a 100 g pocket body
- 8 calibrated wavelengths 📏 — 850 / 980 / 1300 / 1310 / 1490 / 1550 / 1625 / 1650 nm on an InGaAs detector, -70 to +10 dBm at 0.01 dB
- RJ45 cable mapping ✅ — checks UTP/8P8C runs up to 600 m wire-by-wire with the remote identifier stored in the meter base
- Wave ID and modulation detection 🔍 — 270 Hz, 330 Hz, 1 kHz and 2 kHz tone recognition for positive fiber identification
- Rechargeable, all-day battery 🔋 — 3.7 V / 450 mAh Li-ion, Micro-USB charging, over 50 hours of power-meter runtime
- Built for the field 🔧 — REF value setting, user self-calibration, 500-group memory, backlit LCD and an LED torch for dark joint boxes
