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.
