 lists the transmit specifications for the 10GBASE-LR/LW XFP. 

Table 26   10GBASE-LR/LW XFP transmit specifications

Signaling speed (nominal)

10GBASE-LR 10.3125 GBd, 10GBASE-LW 9.95328 GBd

Signaling speed variation 
from nominal (max)

+ or -100 ppm for 10BASE-LR, + or -20 ppm for 
10GBASE-LW

Center wavelength (range)

1260 to 1355 nm

Side Mode Suppression 
Ratio (minimum)

30 dB

Average launch power (max) 0.5 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.

-8.2 dBm

Launch power (min) in OMA 
minus transmission and 
dispersion penalty (TDP) 

-6.2 dBm

Optical Modulation 
Amplitude 

2

(min)

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