Overview and Installation

The Fiber Optic Splitter Module monitors network traffic flowing in either direction on a fiberoptic network
(Ethernet, Fast Ethernet, FDDI, ATM, and SONET) 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 LAN analyzer.

The splitter module is light, compact, and portable. You can also mount as many as three modules in a 19"
equipment rack with our 3-Module Rackmount Kit (RM210; cover any open slots in the kit with Filler Blanks
[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 LAN analyzer, we recommend a Fiber
Optic Analyzer Patch Cable (EFN4029-CT), shown below.
