BRIEF DESCRIPTION
1.1.1
OVERVIEW
The OSD2139 is an unmanaged 2-port media converter supplied in standaline module format with 2
duplex data channels and 2 duplex contact closure channels. It has one 10/100/1000Base-T RJ45
copper port and one SFP port which can be specified by the user for 100Base-Fx/1000Base-Lx/Sx fiber
mode or as 10/100/1000Base-T RJ45 copper.
The unit will operate on either singlemode or multimode fiber. Operation over at least 50km of
singlemode fiber is possible by use of the appropriate SFP optical devices. It normally requires two
fibers but is optionally available for one fiber operation.
A major benefit of the OSD2139 is its reliable and consistent performance over the -20°C to +75°C
temperature range that allows it to be used in uncontrolled environments such as roadside cabinets,
mine sites and factories.
