MIL-195C
Installation
The MIL-195C converter supports full-duplex ATM
Fiber/UTP links. For fiber budget constraints, the MIL-
195C has a launch power of -19 db and a receive
sensitivity of -30 db (using a 1300 nm class 1 laser). In a
full-duplex environment, up to 100m of CAT 5 UTP and
15km single-mode fiber can be used.
To install either converter:
1. Attach the CAT 5 UTP cable from the network to the
RJ-45 port on the device.
Note: Use screened CAT 5 UTP cable for CISPR-22 class B installation.
2. Attach the fiber network cable connectors to the
connectors marked “RX” (Receive) and “TX”
(Transmit).

3. Connect the power receptacle from the wall adapter
to the unit.

The MIL-185C converter supports full-duplex ATM
Fiber/UTP links. For network budget constraints, the
MIL-185C has a launch power of -19 db and a receive
sensitivity of -31 db (using a 850 nm class 1 laser). In a
full-duplex environment, up to 100m of CAT 5 UTP and
2km of multi-mode fiber may be used.
