1 TECHNICAL SUMMARY
1.1 BRIEF DESCRIPTION
1.1.1
OVERVIEW
The OSD2151 is designed to convert between 10/100/1000Base-T copper cabling and 1000Base-Fx
fiber cabling with the added feature of Link Loss Forwarding. It has one RJ45 copper port and one SFP
port which can be specified by the user for one or two fiber configuration.
The OSD2151 incorporates Link Loss Forwarding (LLF) function providing fault detection and shut
down when a link fails.
The unit will operate on either singlemode or multimode fiber. Operation over at least 500m of
multimode fiber or 50km of singlemode fiber is possible by use of the appropriate optical devices.
A major benefit of the OSD2151 is its reliable operation over the -20°C to +65°C temperature range
which allows it to be used in environments such as roadside cabinets, mine sites and factories.
