      Optical interface specifications—see SONET/SDH OC12/STM4 Optical Interface Specifications

    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 OS System Basics and Services Command Reference.


    One tricolor per port:
