For information on which FPCs support these PICs, see T640 PIC/FPC Compatibility.


  • One, two, four, or ten Gigabit Ethernet ports

  • Power requirement:

    • 1-port: 0.25 A @ 48 V (11.9 W)

    • 2-port: 0.25 A @ 48 V (11.9 W)

    • 10-port: 0.62 A @ 48 V (29.9 W)

  • Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network

  • Model number for 1-Port Gigabit Ethernet PIC: PB-1GE-SFP

    Model number for 2-Port Gigabit Ethernet PIC: PB-2GE-SFP

    Model number for 4-Port Gigabit Ethernet PIC: PB-4GE-SFP

    Model number for 10-Port Gigabit Ethernet PIC: PB-10GE-SFP

Hardware features

  • High-performance throughput on each port at speeds up to 1 Gbps

  • Autonegotiation between Gigabit Ethernet circuit partners

  • Full-duplex mode

  • Maximum transmission units (MTUs) of up to 9192 bytes

Software features

  • Virtual Router Redundancy Protocol (VRRP) support

  • 802.1q virtual LANs (VLANs) support

  • 960 destination MAC filters per port

  • Optical diagnostics and related alarms on the 2-port, 4-port, and 10-port PICs (Junos OS Release 8.2 and later)

  • 64 source MAC filters per VLAN on the 1-port, 2-port, and 4-port PICs

  • 1024 source MAC filters per port on the 1-port, 2-port, and 4-port PICs

  • Flexible Ethernet encapsulation on the 1-port, 2-port, and 4-port PICs

  • Multiple tag protocol identifiers (TPID) support on the 1-port, 2-port, and 4-port PICs

  • Source MAC learning on the 1-port, 2-port, and 4-port PICs

  • MAC accounting and policing—Dynamic local address learning of source MAC addresses on the 1-port, 2-port, and 4-port PICs

  • Passive monitoring for IPv4 packets on the 10-port PIC for Junos OS Release 11.1 and later.

Note: The 10-port Gigabit Ethernet PIC with SFP does not support MAC accounting and policing, MAC learning, TPID, or flexible Ethernet encapsulation. 64 source MAC filters per port.

Cables and connectors

  • You can install any transceiver supported by the PIC.

  • Fiber-optic SFP transceivers:

    • Duplex LC/PC connector (Rx and Tx)

    • 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

    • 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

  • Copper transceivers:

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

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

    • Copper interface specifications—see the Hardware Compatibility Tool at

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


Status LED, one bicolor:

  • Off—PIC is not enabled.

  • Green—PIC is operating normally.

  • Red—PIC has an error or failure.

Port LEDs, one pair per port:

  • Link—If green, the port is online; if there is no light, the port is down.

  • Activity—If flashing green, the port is receiving data; if there is no light, the port might be on but is not receiving data.
