Performance Verification
Use the following procedures to verify the warranted specifications of the
OI1125 E/O Transmitter. The recommended calibration interval is one year.
These procedures test the specifications listed in Table 10. Some specifications,
such as the modulator inputs, are checked indirectly in the eye pattern test
matrix.
