A b o u t t h i s M a nu a l
This manual covers the MIL- 1225LS gigabit converter. The terms “MIL-1225LS”
and “converter” are used throughout this document to describe the device.
I n t ro d u c t i o n
The MIL-1225LS is a 1000 Mbps, gigabit Ethernet device that converts short-wave,
multi-mode fiber optic signals to long-wave, single-mode fiber optic signals (and
vice versa). The device has two SC connectors:
•
SM
Port
(1300 nm single-mode fiber)
•
MM
Port
(850 nm multi-mode fiber)
The MIL-1225LS is a stand-alone device, and it has dual-redundant power
supplies for better reliability.

I n s t a l l a t i o n
1. Connect an SC-type, single-mode cable to the
SMF
Port
on the MIL-1225LS.
2. Connect an SC-type, multi-mode cable to the
MMF
Port
on the device.
Note:
A hybrid cable is recommend to compensate for the DMD (Differential Mode Delay) issue
associated with gigabit speeds and some multi-mode fibers.
3. Connect a power cable to
PWR1
. A second, optional power supply may be
connected to the back-up power jack (
PWR2
) to offer redundant power.
4. Supply power to the converter and make sure the
PWR1
(and
PWR2
if
applicable) LED(s) illuminates.
