To extend the life of the laser, when a PIC is not being actively used with any valid links, take the PIC offline until you are ready to establish a link to another device. For information about taking a PIC offline, see the request chassis pic offline command in the JUNOS System Basics and Services Command Reference.

Transmitter wavelength 1290 nm through 1330 nm1530 nm through 1565 nm1530 nm through 1565 nm
Average launch power–6 through –1 dBm–1.0. through 2 dBm0 through 4 dBm
Receiver saturation–1.0 dBm –1.0 dBm–7 dBm
Receiver sensitivity–11 dBm –14 dBm–24 dBm

To avoid damage to the 80-km XFP receiver (XFP-10G-Z-OC192-LR2), we recommend:
  • Use 12 dB of in-line attenuation at 1550 nm for loopback or point-to-point testing.
  • When deploying into active links, measure the incoming fiber receive optical power to make sure it is below –7 dBm at 1550 nm before connecting to the receiver.
