2. Operation
Once you’ve connected the other devices to the Fiber Optic Splitter Module, it will begin operating immediately.
(It’s a passive device and doesn’t need to draw power from anywhere.) The Splitter Module can operate in either
half-duplex or full-duplex mode. It is designed to tap the incoming data on either or both strands of your network’s
fiberoptic lines and send 20% of the signal to the Analyzer Ports for performance evaluation and error detection, as
shown in Figures 2 and 3 below.
The tapped data is fed to the Analyzer Ports at network speed (up to OC3, 155 Mbps) and at normal signal levels.
Signal integrity is guaranteed for the lines (the tapping will not affect either the signal integrity or loading factor);
the Splitter Module regenerates incoming data from the network lines before retransmitting it.
