Cables and connectors

  • You can install any transceiver supported by the PIC.

    Note: Do not install SONET/SDH SFPs in the Gigabit Ethernet port. The port will not recognize the SFP.

  • Fiber-optic SFP transceivers:

    • Duplex LC/PC connector (Rx and Tx)

    • Small form-factor pluggable (SFP) transceivers:

      • 1000Base-LH (model number: SFP-1GE-LH)

      • 1000Base-LX (model number: SFP-1GE-LX)

      • 1000Base-SX (model number: SFP-1GE-SX)

      Optical interface specifications—see the Hardware Compatibility Tool at https://apps.juniper.net/hct/

    • 1000Base-BX (model number pairs: SFP-GE10KT13R14 with SFP-GE10KT14R13, SFP-GE10KT13R15 with SFP-GE10KT15R13, SFP-GE40KT13R15 with SFP-GE40KT15R13)—see the Hardware Compatibility Tool at https://apps.juniper.net/hct/

  • Copper transceivers:

    • Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45 connector

    • 1000Base-T (model number: SFP-1GE-T)

LEDs

OK or Status LED, one tricolor:

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

  • Green—PIC is operating normally.

  • Yellow—PIC is initializing.

  • Red—PIC has an error or failure.

APP LED, one bicolor:

  • Off—Monitoring application is not running.

  • Green—Monitoring application is running under acceptable load.

Port LEDs, one per port:

  • Off—Port is not enabled.

  • Green—Port is online with no alarms or failures.
