TECHNICAL DATA
The electro-optical characteristics described in the following
tables are valid only for use under the recommended operating
conditions.
Recommended Operating Conditions

(min., max.). 50% duty cycle. The supply current does
not include the load drive current of the receiver output. Add max.
45 mA for the three outputs. Load is 50

2 V.
Transmitter Electro-Optical Characteristics
Notes
1. 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
.
2. Transmitter meets ANSI T1E1.2, SONET OC-3, and ITU-T G.957
mask patterns.
Receiver Electro-Optical Characteristics
Notes
1. Minimum average optical power at which the BER is less than
1 x 10
-10
. Measured with a 2

–
1 NRZ PRBS as recommended by
ANSI T1E1.2, SONET OC-3, and ITU-T G.957
2. An increase in optical power of data signal above the specified level
will cause the SIGNAL DETECT to switch from a Low state to a High
state.
3. A decrease in optical power of data signal below the specified level
will cause the SIGNAL DETECT to switch from a High state to a Low
state.
4. Measured by switching the light from <
–
40 dBm to
–
25 dBm.
5. Measured by switching the light from
–
25 dBm to <
–
40 dBm.
Switching from higher power levels increases this time.
6. PECL compatible. Load is 50
into V
CC
–
2 V. Measured under DC
conditions at 25
°
C. For dynamic measurements a tolerance of
50 mV should be added, V
CC
=5 V.
7 PECL compatible. A high level on this output shows that optical data
is applied to the optical input.
