Viavi Solutions (formerly JDSU) physical interface modules are accessory plug-in units designed to extend the testing capabilities of Viavi modular network test platforms such as the T-BERD and MTS series. Each module provides a dedicated physical interface, allowing technicians to connect to and test specific network types without requiring separate standalone instruments.

The range covered by these modules spans multiple generations of transport and data network technologies:

Ethernet Interface: 10 Mbps / 100 Mbps / 1000 Mbps (10/100/1000BASE-T)
E1 Interface: 2.048 Mbit/s PDH interface for G.703/G.704 testing
SFP Interface: Small Form-factor Pluggable transceiver slot for flexible optical or electrical connectivity
E3/DS3/STS1 Interface: 34.368 Mbit/s (E3) / 44.736 Mbit/s (DS3) / 51.84 Mbit/s (STS1) PDH/SONET testing
E4/STM-1(e) Interface: 139.264 Mbit/s (E4) / 155.52 Mbit/s STM-1 electrical interface testing

These modules are intended for use during installation, commissioning, turn-up, and maintenance of PDH, SDH, SONET, and Ethernet transport networks. The modular architecture allows a single test platform to be configured for the specific interface under test, reducing equipment carry and simplifying field workflows.

Please refer to the Viavi Solutions website for full compatibility information and platform-specific specifications.
