About this Manual
This manual covers both the MIL-185C and the MIL-195C
media converters.
The terms “converter” or “device” are used throughout
the document to describe either the MIL-185C or the
MIL-195C.
Introduction
The MIL-185C and the MIL-195C are compact, physical
media converters that allow the user to convert signals
between ATM fiber optic cabling in either multi-mode or
single-mode, and UTP cabling. Both converters support
OC-3 (155Mbps) speeds.
Features
• Fiber budget sufficient to drive 2 km for multi-mode
or 15 km for single-mode fiber
• One SC-type single-mode (MIL-195C) or one SC-type
multi-mode (MIL-185C) connector
• One shielded RJ-45 UTP connector
• External power supply
• Diagnostic LEDs
• Small form factor
