Software features
You can install any transceiver supported by the PIC. For information about installing and
removing transceivers, see the PIC and Transceiver Installation Instructions.

Duplex LC/PC connector (Rx and Tx)
■
Optical interface support—See Table 26 on page 89 and Table 27 on page 90
NOTE: 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.
