TECHNICAL SUMMARY
1.1
PRODUCT DESCRIPTION
The OSD159 is an add-on 8-channel alarm/contact interface that is either configured as a fiber or a
copper transmission system. The system consists of a pair of OSD159s which are designed to provide
duplex transmission of 8 contact closure channels.
The OSD159 can be used as a standalone pair (fiber version) or as an add-on to an existing OSD
system utilising one available RS232 data channel (copper version).
The OSD159 is available in two physical configurations: card or module. The card versions are
designed to fit the 3RU-high 19” OSD370 or OSD350 chassis, which allows multiple OSD card
products to be conveniently powered from and located in the one chassis. The module versions are
intended for isolated use and require an external power source.
The OSD159 system can be used with any standard multimode optical fiber, and is available optionally
for singlemode fiber use, over a single fiber for transmission and reception.
