Juniper Networks M7I - Manual (Page 92)

You can install any transceiver supported by the PIC.
• Duplex LC/PC connector (Rx and Tx)
• SONET/SDH OC3/STM1 small form-factor pluggable (SFP) transceivers:
• 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.
Cables and connectors
