TECHNICAL DATA
The electro-optical characteristics described in the following
tables are valid only for use under the recommended operating
conditions.
Recommended Operating Conditions
Transmitter Electro-Optical Characteristics
Notes
1. Into multimode fiber, 62.5 μm or 50 μm diameter.
2. Laser power is shut down if power supply is below V
TH
and
switched on if power supply is above V
TH
after t
RES
.
Receiver Electro-Optical Characteristics
Notes
1. Average optical power at which the BER is 1 x 10E
–
12. Measured
with a 2
7
–
1 NRZ PRBS and ER=9 dB.
2. An increase in optical power above the specified level will cause the
SIGNAL DETECT output to switch from a Low state to a High state.
3. A decrease in optical power below the specified level will cause the
SIGNAL DETECT to change from a High state to a Low state.
4. AC/AC for data. Load 50
to GND or 100
differential. For dynamic
measurement a tolerance of 50 mV should be added.
5. Supply current excluding Rx output load.
6. PECL compatible. Load is 50
into V
CC
–
2V. Measured under DC
conditions. For dynamic measurements a tolerance of 50 mV should
be added.
