Parameter
Jitter generation (peak to peak)
Jitter generation (rms)
Jitter transfer / Jitter tolerance
3.6
Parameter
TX_DIS assert time
TX_DIS negate time
Time to initialize
Time to initialize after
reset of TX_FAULT/INT
in normal operation
TX_FAULT assert time
TX_DISABLE for reset
RX_LOS assert time
RX_LOS deassert time
2-wire serial clock rate
1. The RX_LOS assert time can be 200 µsec max when the optical input power is greater than -10 dBm immediately prior to the RX_LOS condition.
3.7
The DWDM SFP optical transceiver incorporates a SFP compliant two-wire management interface, which is used for serial
ID, digital diagnostics, and certain control functions. It is modeled on the DWDM SFP MSA Rev. 1.0 specification modified
to accommodate a single two-wire interface address. Details of the protocol and interface are explicitly described in the MSA.
Please refer to the MSA for design reference.

Falling edge of TX_DIS to rise of output signal above
90% of nominal
Upon power up or negation of TX_FAULT due to
TX_DISABLE
From negation of TX_FAULT/INT using TX_DISABLE
Optical power going to 90% of final value
Time from a fault condition to TX_FAULT assertion
Time TX_DISABLE must be held HIGH to reset TX_FAULT
Time from loss of signal to assertion of RX_LOS
Time from nonloss condition to RX_LOS deassertion
