NK6200 Optical Time Domain Reflectometer – 1310/1550/1625nm Wavelength, 100km Test Range, PON Testing & Wireless App Control

Features a 0.5m ultra-short event dead zone for accurate detection of close fiber events and short patch cords.
Operates on single-mode, multi-mode, and hybrid fiber.
Dynamic range up to 45dB for links longer than 60km or high-loss fibers.
At the same time, it houses an OTDR, VFL, LS, OPM, event map, end-face inspection, and optical loss testing in one device.
Real-time online fiber monitoring with effective APD protection.
PON network online testing (online with power) and for (high-port count and/or splitter).
Ethernet remote test and network diagnostic function (Ping, PPOE, traceroute).
Wireless smartphone app to operate remotely and manage data.
Fast charging protocol and power bank function for convenience in the field.
7″ capacitive touch screen with an easy-to-operate intuitive interface (operable with gloves on).
Automatic event analysis and one-click report.
Rugged, portable with a wide operating temperature of (-10°C to +50°C).
