Transmitter
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.
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 a 12.5 MHz square wave pat-
tern with an optoelectronic measurement system (detector and
oscilloscope) with 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 and consideration as in FC-PH Appendix A.
8. Measured with the K28.5 pattern from Chapter II of the FC-PH
at 266MBd.
9. Measured with the K28.7 pattern from Chapter II of the FC-PH
which equals a 133 MHz square wave.

(Values in brackets are for 320 MBd)
Receiver
Notes
1. Pattern: Manchester coding / NRZI (no scrambling)
2. For a bit error rate (BER) of less than 1x10E-12 over a receiver eye
opening of least 1.0ns. Measured with a 2
7
–1 PRBS.
3. For a BER of less than 1x10E-12. Measured in the center of the eye
opening with a 2
7
–1 PRBS.
4. Test method and considerations as in FH-PC Appendix A.
5. Measured with the K28.5 pattern from Chapter II of the FC-PH at
266 MBd.
6. Measured with the K28.7 pattern from Chapter II of the FC-PH
which equals a 133 MHz square wave.
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
into V
CC
–2 V. Measured under DC
conditions. For dynamic measurements a tolerance of 50 mV should
be added for V
