Fiber Optic Splitter Module
1. Overview and Installation
Thank you for purchasing this Fiber Optic Splitter Module. The Splitter Module can help you to monitor
network traffic flowing in either direction on a fiberoptic network (Ethernet, Fast Ethernet, FDDI, ATM,
SONET, etc.) at data rates up to OC3 (155 Mbps). It has four ports:
• Data Ports A and B are each dual SC female 62.5/125-µm multimode fiberoptic connectors that can be
attached to fiberoptic network devices (NICs, switches, routers, etc.).
• Analyzer Ports A and B are both carried on one dual SC female 62.5/125-µm multimode fiberoptic
connector that can be attached to a network analyzer.
The Splitter Module is light, compact, and tough, so it’s quite portable, but you can also mount as many as three
Modules in a 19" equipment rack with our 3-Module Rackmount Kit (our product code RM210; cover any open
slots in the Kit with Filler Blanks, our product code RM211). Run standard 62.5/125-µm multimode fiberoptic
cable (with SC connectors on the Module end) from the Splitter Module to the other devices. For the
connection to the network analyzer, we recommend our special Fiber Optic Analyzer Patch Cable (our product
code EFN4029-CT), shown in Figure 1 below.

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.
