Practical Design Aluminum alloy body with anti-skid knurled design. Pen- type design with a pouch making it portable and easy to check fibre faults with the visual fault. Review: Good range - Good range Review: Great - Works great ## Features - 【Accurate Identification】This visual fault can accurately detect and locate fiber breaks, poor connections, bending, or cracking. The detector will emit a 650nm bright light for fiber tracing, breaks or faults in the fiber will refract the light. - 【Excellent Functions】The fibre tester has multiple functions including constant output power, low battery warning, long battery life, and long- distance detection. It efficiently checks fibre routing and continuity, creating a bright around the faulty area. - 【Widely Used】The universal 2.5mm connector is designed for ST, SC, and FC interfaces, for both single-mode and multi-mode cables. Fiber Optic Cable Tester suitable for integrated wiring systems, fibre optic engineering, CATV engineering, optic network maintenance, optical telecommunications, optical measurement drive engineering, and research. - 【Detection Distance】This visual fault tester with constant output power. The strong red light can travel up to 20- 30 kilometres in the fibre optic cable. High effective power circuits provide stable power in both continuous- and pulsed mode. - 【Practical Design】The stainless steel head and aluminium body design prevents damage from crashes and dust, while aluminum alloy body with anti- skid knurled design. The visual fault pen has a small size and lightweight, pen- type design with a pouch making it portable and easy to check fibre faults with the visual fault. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CH9JL1Y7 | | Best Sellers Rank | 185,442 in DIY & Tools ( See Top 100 in DIY & Tools ) 121 in Network Testers | | Brand | YOPOTIKA | | Colour | Black | | Country Of Origin | China | | Customer Reviews | 4.4 out of 5 stars 40 Reviews | | Included Components | red light pen | | Item Dimensions | 17.5 x 2.6 x 2.6 centimetres | | Item Weight | 146 Grams | | Item dimensions L x W x H | 17.5 x 2.6 x 2.6 centimetres | | Item weight | 146 Grams | | Manufacturer | YOPOTIKA | | Manufacturer Part Number | electriccircuittestingdevice | | Measurement Type | Fault Detection | | Model Number | electriccircuittestingdevice | | Power Source | Battery Powered | | Power source | Battery Powered | | Specification Met | CE, NIST | | Style | fashion | | Style Name | fashion | | Unit Count | 1.0 count | | Upper Temperature Rating | 60 Degrees Celsius | ## Images ![Visual Fault, 30km Fiber Optic Cable Tester Meter Red Light VFL with 2. 5mm Universal Connector for FC/SC/ST Adapter Pen, Fibre Network Cable Test Kit Fibre Light Source Testers - Image 1](https://m.media-amazon.com/images/I/614V8WkWEQL.jpg) ![Visual Fault, 30km Fiber Optic Cable Tester Meter Red Light VFL with 2. 5mm Universal Connector for FC/SC/ST Adapter Pen, Fibre Network Cable Test Kit Fibre Light Source Testers - Image 2](https://m.media-amazon.com/images/I/61nrf-pS2-L.jpg) ![Visual Fault, 30km Fiber Optic Cable Tester Meter Red Light VFL with 2. 5mm Universal Connector for FC/SC/ST Adapter Pen, Fibre Network Cable Test Kit Fibre Light Source Testers - Image 3](https://m.media-amazon.com/images/I/61aOeQzDVXL.jpg) ![Visual Fault, 30km Fiber Optic Cable Tester Meter Red Light VFL with 2. 5mm Universal Connector for FC/SC/ST Adapter Pen, Fibre Network Cable Test Kit Fibre Light Source Testers - Image 4](https://m.media-amazon.com/images/I/51XLVtLW4UL.jpg) ![Visual Fault, 30km Fiber Optic Cable Tester Meter Red Light VFL with 2. 5mm Universal Connector for FC/SC/ST Adapter Pen, Fibre Network Cable Test Kit Fibre Light Source Testers - Image 5](https://m.media-amazon.com/images/I/61j76rdbVkL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good range *by R***R on 5 June 2026* Good range ### ⭐⭐⭐⭐⭐ Great *by S***N on 31 January 2026* Works great ### ⭐⭐⭐⭐⭐ For a freind *by A***R on 11 January 2026* Ok --- ## 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.pt/products/582885911-visual-fault-30km-fiber-optic-cable-tester-meter-red-light](https://www.desertcart.pt/products/582885911-visual-fault-30km-fiber-optic-cable-tester-meter-red-light) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-17*
