Installs in Tripp Lite N482-Series chassis to split optical fiber signals into two outputs, one for user and one for monitoring.

  • Passive OM4 multimode fiber TAP with 40/100 Gb LC to LC ports
  • 70/30 split ratio allows real-time traffic analysis while preserving primary link performance
  • Fiber TAP cassette is optimized for parallel optics and Base-8 connectivity
  • Compatible with N482-00U, N482-01U, N482-02U and N482-04U panels


Fiber Optic TAP Cassette Helps You Monitor and Analyze Network Data
This N482TAP-4MM73LC multimode TAP (traffic access point) cassette is a passive device added to a fiber optic network to enable real-time monitoring. Its optical splitter divides the optical signal into two outputs, one for the downstream device and one for monitoring, without introducing latency or creating a single point of failure. 

Creates a 70/30 Split Ratio for User Traffic and Signal Monitoring
Network monitoring is used to gather data to analyze performance issues, optimize network traffic and uncover security threats in your data center, telecom carrier network or R&D facility. This TAP cassette directs 30 percent of the light to a nearby monitoring device. The remaining 70 percent is transmitted as usual throughout the network without affecting performance.

Compatible with Multimode Cabling
This passive TAP cassette supports 40/100 Gb internally using multimode fiber optic cable, enabling you to perform monitoring and data analysis without causing delays or affecting network performance. It is compatible with recommended cables, including the N820-Series, for connecting to switches, routers and monitoring equipment.

Easy to Install with Compatible Enclosures
The multimode N482TAP-4MM73LC works with N482-00U (fits one cassette), N482-01U (fits five cassettes), N482-02U (14 cassettes) and N482-04U (28 cassettes) chassis. The futureproof-friendly modular design allows you to remove the cassette without replacing the panel or removing other cassettes. The TAP cassette also complies with IEEE 802.3ae (10 Gb) and ANSI T11.2 (Fibre Channel) requirements. A 0.20 dB maximum insertion loss falls under IEEE 802.3ae maximum channel loss spec of <25 dB.

Factory-Terminated Ports Help Reduce Installation Time
The OM4-rated cassette has 12 Duplex LC ports that allow fast, easy connection of cables. The durable plastic cassette comes with dust caps to protect unused ports.

Questions & Answers

An Optical Traffic Access Point (TAP) facilitates real-time monitoring of data flowing between two endpoints in a fiber optic network so network and storage engineers can analyze traffic patterns, optimize network performance and quickly identify security threats. TAPs are typically installed between switches or routers. They split (or copy) an incoming signal from a switch or router, with one branch connecting to another switch or router and the other to a monitoring system. Fiber TAPs are available for various network speeds and fiber optic cable types.

The split ratio indicates how much of the light entering the TAP goes to the connected device and how much is split off and sent to the monitoring device. A 70/30 split means 30% of the light is output to the monitoring port. The two numbers always add up to 100 percent. A 70/30 split will provide a sufficiently strong signal for a monitoring device located relatively close to the TAP while avoiding signal degradation on the primary link.

Most TAPs used in enterprise and cloud data centers are passive. A passive TAP is a relatively simple device with no circuitry or power requirements. Its reliability makes it the preferred choice in mission-critical networks. By contrast, an active TAP requires an external power source to support circuitry that regenerates the incoming signal and transmits it to both the connected device and the monitoring system. A split ratio is not a consideration because both downstream devices get a full-strength signal. However, its power requirements and electronic circuitry make it a potential point of failure.
