EXPERIMENT NO. 9
10Gb/s Optical Communication
To demonstrate and measure the performance of modern 10Gb/s optical
communication in various lengths of fiber, and also to observe dispersive effects along
with dispersion compensation methods.

IMPORTANT: Before making any type of fiber connections, you must clean the
fiber ends with cotton tipped swabs using ethyl alcohol then dry with compressed air.
: When making any type of adjustment to electrical connections, you
be grounded by wearing a grounding strap. The equipment is very sensitive and
all anti-static precautions must be taken.
1. Arrange your setup as shown in Figure 1. Connect a variable optical
attenuator (VOA) to the optical output of the bit error rate tester (BERT) Optical
Transmit/Receive (Tx/Rx) module. Then connect the ouput of the VOA to a 90/10
power splitter. This will allow you to monitor the power at the receiver. The 10% are
should be connected to a power meter for observation, and the 90% are should be
connected to the optical input.
