Agilent/Keysight TP-40-SR-50-70-MR4

The Keysight TP-40-SR-50-70-MR4 is a passive fiber optic tap engineered for non-intrusive network traffic capture and monitoring. Operating at 40G data rates, this multimode tap enables real-time visibility into live networks without introducing performance degradation or service disruption. The device functions passively—requiring no external power—while maintaining signal integrity across 50 µm core diameter multimode fiber at 1300 nm wavelength. Its 70/30 split ratio directs 70% of traffic to monitoring ports and 30% back to the network, supporting both MR4 and QSFP+ 40G-LX4 interfaces via LC connectors.
