It not only has the function of a general optical power meter, but also has a downlink 1490nm and 1577nm wavelength split power measurement designed for 10GE_x005f_x005f_x0002_PON/XGPON, and displays the respective power values of the two wavelengths on the same screen, which can truly grasp the power value of a single wavelength optical signal on the line, and can accurately determine whether the optical power value is up to standard. The function is completely one-click automatic test, the length of the optical fiber link under test, the connector type, the breakpoint position and other information is displayed in a graphical form, and the results are clear and easy to under_x005f stand. The light source and power meter are displayed at the same time, which is convenient for testing the insertion loss, isolation and return loss of optical passive devices. Optical loss measurement steps are as follows: The optical output interface of this series fiber optic cable tester is a replaceable universal interface, and the end face must be kept clean during use. When the instrument is unable to test a normal curve, or the test results are inaccurate, the connector is first considered for cleaning.When cleaning, be sure to do it with both OTDR and visual red light fault location turned off. ## Features - 【16-in-1 Functionality】Intelligent and multi-functional fiber optic cable tester, containing expert OTDR, automatic OTDR, event map, 10G split-wave power meter, general optical power, end state verification, multi-core test, intelligent line diagnosis (optional), loss test, RJ45 line length/line sequence/seeking line, red light, stable light source, illumination, magnifier, wireless charging functions.

RJ45 simple continuity test, miss wirings. *by on Reviewed in the United States May 12, 2026* I got this to test some fiber optic cables and experiment with fiber. It works well and is easy to use. The main option is to test attenuation. To do this you need a known-good cable to use as a reference point, then you can verify another cable to see how much light it passes in comparison. Light source can be built-in red (650nm) laser or external source. This unit doesn’t generate multiple wavelengths of light to test). Unit is decent quality. Good plastic shell with rubber grips. Display has a backlight option that works well. LED flashlight is good enough to see up close. Rechargeable battery via USB C. RJ45 cable tester works, identified proper connections, swapped pairs, swapped wires between pairs, shorted wires, and open wires. It's a nice addition that doesn't make meter any larger. I would buy this unit again. ### ⭐⭐⭐⭐⭐ HIghly Accurate *by on Reviewed in the United States August 30, 2026* This handheld tester is a must-have for network maintenance, offering precise optical power readings and a very handy RJ45 cable test function. The backlit display makes it easy to read measurements in dark server closets, and the Type-C rechargeable battery lasts for days. Storing up to 500 data points makes logging your work seamless ## Frequently Bought Together - 16-in-1 OTDR Optical Fiber Tester 1310/1550nm,4.3' Touch Screen and Event Map OLT (Optical Loss Test), Fiber Tester Built-in VFL OPM LS/OLS/RJ45,Functions RJ45 Cable Tester Network Tools - Jonard Tools M-216C/EX, Impact Resistant Hex Can Wrench with 7/16" and 3/8" Hex Sockets and Ergonomic Handle, 1" Diameter , 7" Length, Outer - Visual Fault Locator 30KM, VFL Fiber Optic Tester Kit - Include Single Mode 9/125um FC Male to LC Female Adapter, Light Pen for Fiber Network Cable Test --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/658752160-16-in-1-otdr-optical-fiber-tester-1310-1550nm-4](https://www.desertcart.jp/products/658752160-16-in-1-otdr-optical-fiber-tester-1310-1550nm-4) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-17*
