    Hi Arthur, 

    You concern is correct - you cannot connect a shortwave port to a longwave port at the other end. The shortwave port requires a multi-mode cable while the longwave port requires a single mode cable. There must be something, like a Fibre Channel switch or FCIP router, in between to do the conversion. 

    Regards,

    John
