The Yamasaki Y42 Singlemode OTDR is a professional fibre optic tester designed for accurate fault detection, insertion loss testing, and network analysis. Operating at 1310/1550nm, the Y42 is ideal for singlemode fibre networks in telecommunications, enterprise, FTTH rollouts, and data centres.
With its integrated OTDR, Visual Fault Locator (VFL), Optical Power Meter (OPM), Light Source (LS), event map, fibre-end inspection, and insertion loss test, it offers a complete solution for contractors and technicians who demand reliability in the field.
Dual Wavelength Testing – Works at 1310nm & 1550nm for singlemode fibre analysis.
Comprehensive Functions – Includes OTDR, VFL, OPM, LS, event map, end-face inspection, and IL test.
High Precision Fault Detection – Short 0.5m dead zone and 3m attenuation zone allow sharper readings near connectors.
Flexible Operation – Choose between automatic or manual modes depending on job requirements.
User-Friendly Design – Operated via colour touchscreen or keypad for convenience in different environments.
Durability Built-In – Shock-resistant, dustproof, drop-resistant, and water-resistant for reliable fieldwork.
Effortless Data Handling – Save and transfer test results via USB or SD card; analyse with included PC software.
Integrated VFL – Red light source at 650nm±20nm with CW, 1Hz, and 2Hz modes for fast visual fault locating.
Tailored for singlemode fibre networks where precision and low-loss testing are critical.
Combines multiple testing tools in one portable device, reducing kit weight.
Shorter dead zone compared to many OTDRs means you can pinpoint faults closer to connectors.
Designed for field contractors who need durability without sacrificing accuracy.
Backed by fibresales warranty and support, with local stock available.
Telecommunications – Testing and troubleshooting long-haul and access networks.
FTTH Rollouts – Verifying new fibre installations with accurate splicing and loss detection.
Enterprise Networks – Maintaining and testing singlemode backbones for corporate systems.
Data Centres – Locating and fixing fibre faults in high-density, mission-critical environments.
Field Installations – Portable, rugged design makes it reliable for use in outdoor and industrial environments.
