Datasheet

Overview

The VIAVI Trilithic 1G DSP with OPM/VFL Pro (part number TRI-DSP-1G-D31-VFL-PRO) is a plant maintenance meter in the DSP Series. It combines CATV, DOCSIS 3.1 cable modem, Gigabit Ethernet and optical testing in one instrument for systemwide testing, and adds a built-in optical power meter (OPM) and visual fault locator (VFL) to the 1G DSP Pro configuration.

The meter achieves throughput testing speeds of up to a gigabit per second using a dedicated Ethernet test port or the internal cable modem. It performs roundtrip or one-way Key Parameter Index (KPI) measurements with constant payload testing for Layer 2 through Layer 4, for verification of Ethernet Service Level Agreement (SLA) and Quality of Service (QoS) metrics.

Optical testing

The optical hardware package includes a built-in FTTx-ready optical power meter for testing passive optical networks, with absolute and relative measurements at the ITU-T G983.3 recommended wavelengths of 1310 nm, 1490 nm and 1550 nm and interchangeable FC, SC and ST style adapters. The VFL emits a Class III visible red laser for locating loss points in patch cords, patch panels and enclosures on damaged single-mode and multi-mode fiber.

Operation

The 1G DSP has a large, high-resolution color touchscreen, simple pass/fail indicators and autotest apps. It supports remote meter control via a web browser, up to five user profiles, long battery life with a quick charge time, and a glow-in-the-dark keypad. Test results and configurations can be synchronized with VIAVI StrataSync over Ethernet, DOCSIS or WiFi.
