HD8² LC 2-Port TAP Cassettes

Fiber TAP/Monitor cassettes provide space for network administrators to plug in monitoring equipment for troubleshooting and monitoring the network. Optical data is split into two parts (called a split ratio) in a specific split ratio for transmission and tapping/monitoring. For instance, if an optical tap cassette has a split ratio of 90:10, the 90% power light will be used for transmission and the 10% part will be used for monitoring. Complete network visibility requires access to all network segments and often requires multiple copies of the same signal to feed a variety of analytic devices. A TAP cassette has multiple tap splitters based on the number of designed outputs. Each signal (per TAP splitter) is split to “live” and “monitoring” output signals at a pre-determined ratio — typically 50/50 or 70/30 (70 live and 30 monitoring). A 70/30 split ratio is generally the preferred method, as it dedicates a higher percentage for network traffic, avoiding any dropped packets. The 70/30 split is most commonly used in 1 Gb/s and 10 Gb/s networks; however, at higher speeds such as 40 Gb/s and 100 Gb/s, the 50/50 ratio is more commonly used in order to meet power budgets.

LC Internal Shuttered adapters are available with VFL traceable fiber optic connections, when trying to trace the adapter using a visible light source you can see the red light glowing through the adapter sleeve.

• TAPs pass all link traffic for monitoring. Even corrupt data will not be rejected so everything can be seen in real time.
• They are invisible to the network: they place no burden on the network and don’t affect any packets or data transmitted through the link.
• There is no programming or switch configuring required with a passive TAP.
• They offer full duplex port monitoring with a transmit and receive path that is scalable at data rates.
• TAPs that are built into the existing patching environment reduce the number of connections required.
