GTS1063 and GTS1250 GBIC Test Systems Instruction Manual
10. Verify that, after 32 acquisitions have completed, the Mean value of the
RECOV DATA amplitude measurement is
u
300 mV and
t
600 mV. Record
the value on the test record.
Tx Data Duty Cycle
Equipment
required
One sampling oscilloscope with SD22 sampling head
Two Semi-rigid cables for SD22 sampling head
One optical cable
GBIC, 1.25 GB/s
One coaxial cables
Prerequisites
See page 43
NOTE
. Make sure that the optical connector ends of both the fiber and the input
to the GTS1250 are well cleaned before performing this step.
1. Connect your wrist strap to the antistatic connector on the front of your
oscilloscope.
NOTE
. The longer wavelengths of 1310 nm and especially 1550 nm are sensitive
to loss in fiber due to bending of the fiber. The fiber bend radius of the GTS1250
fiber input should lay with >1.5 inch bend radius along the fiber’s entire length.
This precaution must be maintained throughout the entire performance
verification procedure.
2. Install a GBIC in the GBIC Test System, and connect the optical fiber
between the Tx and Rx connectors of the GBIC.
3. Connect SMA cables between the GBIC Test System and the oscilloscope as
shown in Figure 21.
4. Set the GBIC Test System Transmit pattern to PRBS7.
