Agilent/Keysight TPX-40-SR-50-70-MTP

The Keysight TPX-40-SR-50-70-MTP is a passive fiber optic tap engineered for non-intrusive network traffic visibility across high-speed Ethernet deployments. This MTP-connector module operates entirely without power, eliminating external dependencies while maintaining 100% traffic access for monitoring and security applications. The 50 µm multi-mode design supports 100G (4x25G QSFP28), 40G, and 4x10G standards at 850 nm wavelength, delivering full-duplex operation with insertion losses of 4.4 dB / 4.4 dB or 2.6 dB / 6.6 dB across its 70/30 split ratio.
