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.
