Relative Input Optical Power (dB)
The figure shows the relationship between typical trade-off of BER and Relative Input Optical Power. Besides the
required BER =1
× 10−10 of the ATM Forum 155.52 Mbps Physical Layer Standard, The transceiver can be operated at
other Bit-Error-Rate conditions. The Relative Input Optical Power in dB is referenced to the actual sensitivity of the
device. For BER conditions better than 1
× 10−10, more input signal is needed (+dB).
