    Hello, 
    You can check this link indicates every thing between both in  a brief
    https://www.juniper.net/content/dam/www/assets/datasheets/us/en/routers/optic-modules.pdf

    CTP-SFP-1GE-SX was designed for  series before in juniper carry the prefix CTP " circuit to packet " but now EOL as per the below link :
    https://support.juniper.net/support/eol/product/ctp_series/

    EX-SFP-1GE-SX is designed for EX series which exist now and some of them announced their its EOL as well "  I mean the switches " 

    So, there is no difference in the speed between both SFPs and to be assure from the compatibility of the product you are going to plug this SFP in,  you shall check the below hardware combability tool:
    https://apps.juniper.net/hct/product/

    So, you will be able to specify which SFP will work fine and on which Junos version.

    Please if my answer helped You , appreciate to mark it as a solution ..
    Thanks ..

    Juniper has lots of optics that are physically the same but marked and sold under different part numbers. This is probably some legacy from when it was deemed better to have one part number per series for the modules for marketing reasons. Who would by an EX-SFP-1G-LR for their MX960? That said, not all similar part number are actually compatible.

    From our SE team I have heard that Juniper is focusing on unifying the optic module flora and will and have certify some "common" modules for multiple product series. Examples:
    SFPP-10G-LRT2-C
    SFPP-10G-SR-C
    SFPP-10G-USR-C
    The -C at the end stands for "common". The unified part numbers obviously simplify things greatly and also add the benefit of more reasonable prices compared to 3:rd party optics.

    Look for -C part numbers in the future. If you already have CTP- SFPs, they most probably work, but check the Hardware Compatibility Tool to be safe.
