This document covers both the MIL-140CRM and the
MIL-140TRM media converter modules. The terms
“MIL-140” and “converter” are used throughout this
document to describe these devices.
I n t ro d u c t i o n
The MIL-140 converters are part of a series of modules
designed to be installed into MiLAN's Media
Conversion System. These half-/full-duplex devices
convert Ethernet optical signals to electrical and vice-
versa.
The converter has a signal capability of transmitting up
to 2 km (subject to fiber budget and collision domain
restrictions). This module also has the Link Sentry
feature.
