JDSU PIM-DS1-DS3-STS1-SFP Physical Interface Module

The JDSU PIM-DS1-DS3-STS1-SFP is a multi-interface Physical Interface Module designed for use in JDSU test platforms, delivering DS1, DS3, E3, and STS-1 connectivity along with an SFP slot for flexible transceiver options. This module lets technicians connect copper DS1/DS3 or E3 lines and SONET/SDH STS-1 traffic to compatible JDSU instruments for measurement, validation, and service verification of telecom circuits. The integrated SFP interface supports inserting standard transceivers to accommodate fiber-based testing within the same module, reducing the need for separate interface cards. Built to slot into JDSU modular test systems, it provides a compact, single-card solution when multiple physical interfaces are required for network testing scenarios that involve legacy and modern transport methods. Use cases include lab bench testing and field verification of networks that carry DS1, DS3, E3, or STS-1 signals, enabling accurate probing and diagnostics through a unified interface module.
