Note 2: For data rate > 3 Mb / s, the duty factor must be such as kept 25 to 75%. High level output when optical flux
is received. Low level output when optical flux is not received.
Note 3: All Plastic Fiber (970 / 1000 µm).
Note 4: Between input of a fiber optic transmitting module and output of TORX176.
Note 5: BER ≤ 10−9, rated by peak value.
