40-Gigabit Ethernet PIC with CFP (T640 Router)


Software release


  • One 40-Gigabit Ethernet port

  • Power requirement: 1.46 A @ –48 V (70.0 W)

  • Model number: PD-1XLE-CFP

Hardware features

  • Maximum transmission units (MTUs) up to 9192 bytes

Software features

  • Media Access Control (MAC) accounting

    Note: MAC accounting on this PIC is not supported when aggregated Ethernet is configured.

  • Source and destination MAC address filtering

  • Ethernet OAM 802.3ah (remote loopback is not supported for this PIC)

  • Layer 2 filtering and accounting based on Layer 2 headers

  • Multiple tag protocol identifiers (TPIDs) used for filtering and counting

  • Flexible virtual LAN (VLAN) tagging

  • Channels defined by two stacked VLAN tags

  • Layer 2 protocols:

    • Flexible Ethernet service

    • Ethernet circuit cross-connect (CCC)

    • Ethernet translational cross-connect (TCC)

    • Ethernet virtual private LAN service (VPLS)

    • VLAN CCC

    • Extended VLAN TCC


    Layer 3 protocols:

    • IPV4

    • IPV6

    • MPLS

  • Optical control features (vendor dependent)

  • IEEE 802.3ad Link Aggregation

  • Graceful Routing Engine switchover (GRES)

Note: The 40-Gigabit Ethernet PIC with CFP does not support Layer 2 egress interface rewrite rules (egress IEEE802.1P rewrite-rules).

Cables and connectors

  • Duplex SC/PC connector (RX and TX)

  • 40-Gigabit Ethernet CFP transceiver: 40GBASE-LR4 (model number: CFP-40GBASE-LR4)

  • Optical interface specifications—see the Hardware Compatibility Tool at
