 lists the transmit specifications for the 10GBASE-ZR/ZW XFP.

6 Stressed eye jitter is a test condition for measuring stressed receiver sensitivity. It is not 

a required characteristic of the receiver.

Signaling speed (nominal)

10GBASE-ZR 10.3125 GBd, 10GBASE-ZW 9.95328 GBd

Signaling speed variation 
from nominal (max)

+ or -100 ppm for 10BASE-ZR, + or -20 ppm for 
10GBASE-ZW

Center wavelength (range)

1530-1565 nm

Side Mode Suppression 
Ratio (minimum)

30 dB

Average launch power (max) 4.0 dBm

Average launch power

1

 (min)

1 Average launch power (min) is informative and not the principal indicator of signal 

strength. A transmitter with launch power below this value cannot be compliant, 
however, a value above this does not ensure compliance.

 (min)

2 Even if the TDP < 1 db, the OMA (min) must exceed this value.

Average launch power of 
OFF transmitter

3

 (max)

3 Examples of an OFF transmitter are: no power supplied to the PDM, laser shutdown for 

safety conditions, activation of a PMD_global_transmit_disable or other optional 
transmitter shut down conditions.
