Datasheet

Overview

The 1G DSP with OPM/VFL Sweep (part number TRI-DSP-1G-D31-VFL-SWEEP) is the plant maintenance model of the VIAVI Trilithic DSP Series. It is listed as a plant maintenance meter with active sweep, an optical power meter and a visual fault locator. One instrument combines CATV, DOCSIS 3.1 cable modem, Gigabit Ethernet and optical testing for systemwide work.

The meter runs throughput tests at up to a gigabit per second through a dedicated Ethernet test port or the internal cable modem. It can make roundtrip or one-way Key Parameter Index (KPI) measurements, and its constant payload testing for Layer 2 through Layer 4 checks Ethernet Service Level Agreement (SLA) and Quality of Service (QoS) metrics.

Optical testing

The OPM/VFL hardware package adds a built-in FTTx-ready optical power meter for testing passive optical networks. It makes absolute and relative measurements at 1310 nm, 1490 nm and 1550 nm, with interchangeable FC, SC and ST style adapters. The visual fault locator emits visible red light to find loss points in patch cords, patch panels and enclosures, and to locate light escaping from damaged single-mode and multi-mode fiber.

Sweep functions

The Sweep model adds the RSA high-resolution return sweep (with the 8310 RSA), forward active sweep (with the 8300 FST), the SSR high-speed return sweep and SST Compare (with the 9581 SST). With these, the meter can work as a return path sweep transmitter, set the tilt and gain of distribution amplifiers, and find bursty ingress.

Operation

The 1G DSP has a large, high-resolution color touchscreen, pass/fail indicators and autotest apps. It also offers remote control through a web browser, long battery life with a quick charge time, and a glow-in-the-dark keypad. Test data and instrument assets can be synced with StrataSync over Ethernet, DOCSIS or WiFi.
