10Gb/s OPTICAL TRANSCEIVER INTERFACE /
EXTERNAL LASER (L7)
The10Gb/s External Laser Transceiver card performs both E/O and O/E
conversions for the OTS system. This card contains both an external laser
interface for the OTS9100 system and a broadband optical receiver. The
L7 Optics card works in conjunction with the Transmit card, which
contains all of the transmitter functionality for the OTS system. The L7
Optics transceiver also works in conjunction with the Receive card,
which contains all of the receiver functionality and analysis capability for
the OTS system.
Figure B-4 shows the External Laser Transceiver card front panel.
Module OK
The Module OK LED should be green while the instrument is running.
On power up, the LED first lights red, then changes to green when the
system has finished initializing.
NOTE: If the LED remains red after the system has finished initializing
or fails to light at all, call Tek service.
Optical OUT
The Optical Output is a modulated version of the External Laser Optical
Input. The optical connector can be configured with field
interchangeable shells: FC (standard), ST, or SC type. The field
interchangeable shells are easily removed to allow cleaning of the optical
connector.
The LED found above the Optical OUT heading will flash amber for five
seconds and then change to green when both the optical output is
activated and the external laser is active. The LED may also be green if
the external laser is active, even if the optical output has not been
enabled.
NOTE: If the LED flashes red, continues to flash amber, or fails to light
at all, call Tektronix for service.
WARNING: Always avoid exposure to the laser beam.
Before power is applied to the OTS9100 system, be sure that all
laser outputs are either covered with the screw cap provided or
connected to the appropriate circuit.
