Transmitter Electro-Optical Characteristics
Notes
1. Measured at the end of 5 meters of 62.5/125/0.275 graded index
fiber using calibrated power meter and a precision test ferrule.
Cladding modes are removed. Values valid for EOL and worst-case
temperature.
2. The input data pattern is a 12.5 MHz square wave pattern.
3. Center wavelength is defined as the midpoint between the two
50% levels of the optical spectrum of the LED.
4. Spectral width (full width, half max) is defined as the difference
between 50% levels of the optical spectrum of the LED.
5. 10% to 90% levels. Measured using the 12.5 MHz square wave
pattern with an optoelectronic measurement system (detector
and oscilloscope) having 3 dB bandwidth ranging from less than
0.1 MHz to more than 750 MHz.
6. Extinction Ratio is defined as PL/PH x 100%. Measurement system
as in Note 5.
7 Test method as for FDDI-PMD. Jitter values are peak-to-peak.
8. Duty Cycle Distortion is defined as 0.5 [(width of wider state) minus
(width of narrower state)]. It is measured with stream of Idle
Symbols (62.5 MHz square wave).
9. Measured with the same pattern as for FDDI-PMD.
10.Measured with the Halt Line state (12.5 MHz square wave).
Receiver Electro-Optical Characteristics
Notes
1.
For a bit error rate (BER) of less than 1x10E–12 over a receiver eye
opening of least 1.5 ns. Measured with a 2
7
–1 PRBS at 194 MBd.
2. For a BER of less than 1x10E-12. Measured in the center of the eye
opening with a 2
7
-1 PRBS at 194 MBd.
3. Measured at an average optical power level of –20 dBm with a 62.5
MHz square wave.
4. All jitter values are peak-to-peak. RX output jitter requirements are
not considered in the ATM standard draft. In general the same
requirements as for FDDI are met.
5. Measured at an average optical power level of –20 dBm.
6. Measured at –33 dBm average power.
7 An increase in optical power through the specified level will
cause the SIGNAL detect output to switch from a Low state to
a High state.
8. A decrease in optical power through the specified level will
cause the SIGNAL detect output to switch from a High state to
a Low state.
9. PECL compatible. Load is 50

conditions. For dynamic measurements a tolerance of 50 mV should
be added for V
