    • Short reach (SR-1) (model number: SFP-1OC48-SR)

    • Intermediate reach (IR-1) (model number: SFP-1OC48-IR)

    • Long reach (LR-1) (model number: SFP-1OC48-LR)

    Optical interface specifications—see SONET/SDH OC48/STM16 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 System Basics and Services Command Reference.


OK LED, one tricolor:

  • Off—PIC is offline and safe to remove from the router

  • Green—PIC is operating normally

  • Yellow—PIC is initializing

  • Red—PIC has an error or failure

APP LED, one green per port:

  • Off—Service is not running

  • Green—Service is running under acceptable load

Port LEDs, one tricolor per port:

  • Off—Not enabled

  • Green—Online with no alarms or failures

  • Yellow—Online with alarms for remote failures

  • Red—Active with a local alarm; router has detected a failure
