Stressed Receive sensitivity
Stressed Receive sensitivity OMA
Vertical Eye-closure Penalty
Deterministic Jitter
Total Jitter
Output Data Rise/Fall time
Receiver 3dB upper cutoff frequency
1260 to 1360nm
Optical Isolation
from External
1550 to 1560nm
Source
1640 to 1665nm
Note (1). Measured with 1490nm, ER=9dB; BER =<10
Note (2). Specified with minimum optical extinction ration of 9dB.
Note (3). When LOS asserted, the data output is Low-level (fixed)
Note (4). When the terminal is viewed from the optical path, the reflection toward the optical path of the
optical signal with a central wavelength of 1480nm to 1500nm transmitted to terminal.
Note (5). These are 20%~80% values

Note (1). A (TX)+ B (RX) = 300mA
(A: Not include termination circuit; B: using a resister of 150Ω between Data-output and ground)
Note (2). There is an internal 4.7 to 10kΩ pull-up resistor to VccT.
Note (3). Pull up to V
CC
Note (4). Internally AC coupled with CML output, but requires a 100Ohm differential termination at or
internal to Serializer/ Deserializer.
