6.4 MINI OTDE Optical Transceiver
6.4.1 Overview
Figure 6-16 MINI OTDE Optical Transceiver
Areas of Application
The MINI OTDE optical transceiver is used to connect a DTE with an AUI port to
an optical network and to establish a fiber-optic link between two DTEs. The MINI
OTDE provides electrical isolation with the fiber-optic cable (FO). This results in
immunity to electromagnetic interference. The optical transceiver can be plugged
directly into the AUI port of the DTE. If the module is fixed using the wall mounting,
the MINI OTDE can be connected to the DTE using the 727-1 drop cable. The
major advantages of the MINI OTDE optical transceiver are its small dimensions
and compact design.
The optical port of the MINI OTDE is implemented as two BFOC/2.5 female
connectors (ST compatible). A glass fiber-optic cable with graded fibers (Type
62.5/125 µm fibers) can be connected.
Note
Removing and reinserting the MINI OTDE with the power supply turned on can
lead to disturbances on the DTE (for example restarting a PC).
