...Tektronix bit error rate tester...

Tektronix bit error rate tester. Capable of operating at up to 700 megabits per second, this BERT allows students to do an end-to-end test of a fiber optic telecommunications system. Student researchers developed an inexpensive method to multiplex the signal so that several systems can be tested by student groups using only one transmitter. Since each transmitter costs >$25,000, this represents a substantial savings.
