The G-Link TRP800 PON OTDR is a specialized optical time domain reflectometer designed to meet the rigorous demands of modern FTTx and PON network maintenance. As fiber networks become more complex, technicians need a PON OTDR that can see through high-count splitters and accurately locate faults.
The TRP800 stands out with its exceptional 45dB dynamic range, allowing it to test through 1:128 splitters effortlessly. Whether you are conducting acceptance tests for new broadband access or troubleshooting active lines using the 1625nm live testing port, this device ensures precision and efficiency. With its built-in Intelligent Link Mapper, even technicians with minimal optical experience can interpret results instantly through intuitive “Pass/Fail” icons.
Designed for the field, it features a rugged casing, a large 7-inch touchscreen, and a battery life exceeding 8 hours, making it the reliable choice for telecom operators and contractors.

Frequently Asked Questions (FAQ)
Answer: Yes, absolutely. The TRP800 includes a specific model equipped with a dedicated 1625nm wavelength port. This allows technicians to perform in-service troubleshooting on active PON networks without interfering with the data transmission signals (usually at 1310/1490/1550nm), ensuring zero downtime for your customers.
Answer: The TRP800 High-Performance model features an industry-leading 45dB dynamic range. This power enables it to effectively test through high-count optical splitters, up to 1x128, making it an ideal solution for certifying modern FTTH and deep-fiber deployments.
Answer: No, extensive training is not required. The TRP800 features an Intelligent Link Mapper (Smart Link) mode. Instead of complex waveforms, it displays the fiber link status using intuitive Pass/Fail icons and an easy-to-understand event map. This allows technicians of any skill level to quickly identify faults like breaks, macro-bends, or bad splices.
Answer: The TRP800 is a complete 4-in-1 field toolkit. Besides the high-performance OTDR, it integrates an Optical Power Meter (OPM), a Visual Fault Locator (VFL) for identifying close-range breaks, and a Stable Light Source (LS). It also supports an external USB Fiber Inspection Probe (FIP) for checking connector end-faces.
Answer: The device is built for long field shifts. It is powered by a high-capacity lithium battery that provides $\ge$ 8 hours of continuous operation on a single charge, ensuring you can complete a full day's work without needing a power outlet6.
Answer: The specialized FTTx Mode is designed to automatically identify and analyze the topology of Passive Optical Networks. It can detect and display the number of splitter ports and their locations in an easy-to-read chart format, greatly simplifying the maintenance of complex distribution networks.
