Gigabit Ethernet PIC with SFP (M7i Router)
Junos OS Release 6.3 and laterSoftware release
One Gigabit Ethernet port
Power requirement: 0.15 A @ 48 V (7.3 W)
Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network
Description
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
Hardware features
Virtual Router Redundancy Protocol (VRRP) support
802.1q virtual LANs (VLANs) support
960 destination MAC filters per port
Flexible Ethernet encapsulation
Multiple tag protocol identifiers (TPID) support
Source MAC learning
MAC accounting and policing—Dynamic local address learning of source MAC addresses
Software features
You can install any transceiver supported by the PIC.
Fiber-optic small form-factor pluggable (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 Gigabit Ethernet 1000BASE Optical Interface
Specifications
Copper SFP transceiver:
Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45
connector
