    What are the 48 port physical interfaces of the QFX5100-48S-6Q?  Are they fixed fiber ports, copper ports?  I need (4) 1G fiber ports, but not sure how this switch is physically laid out.

    It seems 1G is supported based on below doc:


    • QFX5100-48S-AFO/AFI:
    - 1GbE SFP: 48 (24 copper 1GbE)
    - 10GbE SFP+: 48/72 (with breakout cable)
    - 40GbE QSFP+: 6

    You can find the datasheet here:

    QFX5100-48S has 48x 1G/10G fixed fiber ports.

    If you plan to buy a new QFX5100 device, please keep in mind that this platform is already EOL announced:

    QFX5100-48S: Data center access switch with 48 small form-factor pluggable and pluggable plus (SFP/SFP+) transceiver ports and six quad SFP+ (QSFP+) ports with an aggregate throughput of 1.44 Tbps or 1.08 Bpps per switch.   

    SFP = 1g 
    SFP+ = 10g 
    QSFP+ = 40g
