Viavi Solutions (formerly JDSU) Plug-In Modules (PIMs) are interchangeable test modules designed for use with Viavi modular network test platforms. They allow technicians to configure their test equipment for specific network technologies and interface types without requiring separate dedicated instruments.

The E3/DS3/STS1 PIM modules support testing at the following rates and interface types:

E3 Rate: 34 Mbit/s
DS3 Rate: 44.736 Mbit/s
STS-1 Rate: 51.84 Mbit/s
Interface Coverage: PDH and SONET tributary interfaces
Design: Plug-in modular format for compatible Viavi/JDSU test platforms

Typical applications include bit error rate testing (BERT), framing and alarm analysis, and performance monitoring across PDH and SONET network elements. These modules are commonly used in legacy and transitional transport network environments where E3, DS3, and STS-1 interfaces remain in service.
