Designed for fiber installation, troubleshooting and maintenance in FTTx, telecom, LAN and data communication networks. - 【1310/1550nm Professional OTDR Testing】 Dual-wavelength 1310/1550nm single-mode OTDR provides a 24/22 dB dynamic range and 500 m to 64 km measurement range. With an event dead zone ≤3 m, attenuation dead zone ≤8 m and up to 128k sampling points, it helps locate breaks, connectors, splices, macro-bends and other fiber events with detailed waveform and event data. - 【OPM & Stable Light Source for Fiber Loss Testing】 The built-in optical power meter supports 800–1700 nm wavelengths with a -70 to +6 dBm measurement range, while the stabilized light source outputs 1310/1550nm signals at ≥-5 dBm. Multiple modulation modes including CW, 270Hz, 330Hz, 1kHz and 2kHz make it suitable for optical power measurement and insertion-loss testing. - 【30mW VFL & RJ45 Cable Testing】 The 650nm visual fault locator delivers ≥30 mW output with CW, 1Hz and 2Hz modes to quickly identify fiber breaks, tight bends and faulty connectors. RJ45 sequence testing and cable tracking up to 1000 m add practical troubleshooting capability for network cabling, allowing technicians to handle both fiber and Ethernet maintenance with one device. - 【3.5-Inch Touchscreen, Data Storage & Long Battery Life】 Operate test functions and parameters through the 3.5-inch color touchscreen and physical keypad. The tester stores more than 700 records internally, supports expandable TF card storage and standard SOR files, and includes USB Type-C connectivity. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0H5JRKQMW | | Best Sellers Rank | #413,217 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #803 in Network & Cable Testers | | Brand | GOYOJO | | Brand Name | GOYOJO | | Color | BLACK | | Customer Reviews | 5.0 out of 5 stars 1 Review | | Included Components | Accessories | | Manufacturer | goyojo | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | AA-301990-SD | | Power Source | Battery Powered | | Style | black | | Style Name | black | | Unit Count | 1 Count | ## Product Details - **Brand:** GOYOJO - **Color:** 2km - **Item Weight:** 0.4 kg - **Power Source:** Battery Powered - **Style:** 2KM ## Images ![OTDR Fiber Optic Tester 1310/1550nm, 3.5" Touchscreen Fiber Tester with OPM/OLS, VFL, RJ45/RJ11 Cable Test, 5m-64km Testing Range, Multifunction Optical Time Domain Reflectometer for FTTH Telecom - Image 1](https://m.media-amazon.com/images/I/71ySZkciD2L.jpg) ![OTDR Fiber Optic Tester 1310/1550nm, 3.5" Touchscreen Fiber Tester with OPM/OLS, VFL, RJ45/RJ11 Cable Test, 5m-64km Testing Range, Multifunction Optical Time Domain Reflectometer for FTTH Telecom - Image 2](https://m.media-amazon.com/images/I/71eJA7IcroL.jpg) ![OTDR Fiber Optic Tester 1310/1550nm, 3.5" Touchscreen Fiber Tester with OPM/OLS, VFL, RJ45/RJ11 Cable Test, 5m-64km Testing Range, Multifunction Optical Time Domain Reflectometer for FTTH Telecom - Image 3](https://m.media-amazon.com/images/I/81ieJEtFkfL.jpg) ![OTDR Fiber Optic Tester 1310/1550nm, 3.5" Touchscreen Fiber Tester with OPM/OLS, VFL, RJ45/RJ11 Cable Test, 5m-64km Testing Range, Multifunction Optical Time Domain Reflectometer for FTTH Telecom - Image 4](https://m.media-amazon.com/images/I/71zAYY9K7gL.jpg) ![OTDR Fiber Optic Tester 1310/1550nm, 3.5" Touchscreen Fiber Tester with OPM/OLS, VFL, RJ45/RJ11 Cable Test, 5m-64km Testing Range, Multifunction Optical Time Domain Reflectometer for FTTH Telecom - Image 5](https://m.media-amazon.com/images/I/71gHrOK9HsL.jpg) ## Available Options This product comes in different **Color** options. ## Frequently Bought Together - TL280 Cable Fault Tester TDR Cable Fault Locator Coaxial Cable Communication Cable Wire Fault Locater Tester 2km - 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 - Jonard Tools JIC-375 Three Hole Fiber Optic Stripper with TPR Handle, 6" Length, Оne Расk --- ## 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.hr/products/632187998-otdr-fiber-optic-tester-1310-1550nm-3-5-touchscreen-fiber](https://www.desertcart.hr/products/632187998-otdr-fiber-optic-tester-1310-1550nm-3-5-touchscreen-fiber) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-02*
