Notes
1.
Into multimode fiber, 62.5 μm or 50 μm diameter.
2. Laser power is shut down if power supply is below V

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. PECL compatible. Load is 50
into V
CC
–2V. Measured under DC
conditions. For dynamic measurements a tolerance of 50 mV should
be added.
5. Supply current excluding Rx output load.
