  • Multimode (model number: SFP-OC3-SR)
  • Intermediate reach (IR-1) (model number: SFP-OC3-IR)
  • Long reach (LR-1) (model number: SFP-OC3-LR)

  Optical interface specifications—see SONET/SDH OC3/STM1 Optical Interface Specifications

• SONET/SDH OC12/STM4 small form-factor pluggable (SFP) transceivers:
  • Short reach (SR-1) (model number: SFP-OC12-SR)
  • Intermediate reach (IR-1) (model number: SFP-OC12-IR)
  • Long reach (LR-1) (model number: SFP-OC12-LR)

  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.
