Eaton N482TAP-4SM73M8 Single Mode 8 Fiber MPO TAP Cassette 70 30 Split

Overview

The Eaton N482TAP-4SM73M8 is a passive fiber-optic network TAP module designed for high-density, high-speed data centre environments where you need real-time monitoring of single-mode fiber links without impacting the live traffic. It handles 8-fiber MPO to MPO connectivity in a compact cassette form, splitting approximately 70% of the optical signal for the live link and 30% for the monitoring path×hence the "70/30" designation. Internally the module is optimized for 40- and 100-gigabit applications and supports use in the Eaton/Tripp Lite N482 series fiber enclosure panels (such as N482-00U, N482-01U, N482-02U, N482-04U) so you can slide the TAP cassette into a compatible chassis. From a network engineer's perspective: this is the device you deploy when you have a critical backbone fiber link (e.g., between aggregation switches, spine-leaf interconnects or core routers) and you want to mirror or monitor the traffic for security, analytics or performance without introducing latency or a single point of failure. The passive nature means it uses no power and does not regenerate the signal×rather, it splits it. It's suitable for environments where uptime and integrity are non-negotiable.
In practice you'd rack-mount it (in the appropriate chassis), connect the live link MPO ports through it, then connect the monitor ports to your packet-capture or analytics device. Because it uses a 70/30 split you preserve roughly 70% of the light signal to the live link, which helps ensure link integrity and avoids disrupting normal operations.

Key Features

• Passive single-mode TAP cassette for 8-fiber MPO to MPO links×no power required, high reliability.

• 70/30 split ratio (70% live traffic / 30% monitoring) enables mirror-traffic capture without compromising the production link.

• Designed for 40/100 Gb links and compatible with high-density fiber infrastructure and Eaton N482 chassis.

• Factory-terminated MPO ports, very low insertion loss, lifetime limited warranty×simplifies deployment and helps ensure serviceability.
