1742.0. "Fiber characteristics" by ANNECY::MAIGRET_Y () Thu Dec 01 1994 12:42

    Hello,
    
    
    We proposed a FDDI configuration to a customer, and he wants to know
    the fiber optic characteristics used for the dual rings, and to connect
    the systems to the DECconcentrator with multimode MOD-PMD connectors.
    
    If I am not in the appropriate notes file, please let me know.
    
    Regards,
    Yves.

    He needs to have 62.5/125 micron fiber, with a Numerical Aperture of 
    0.275, a modal bandwidth of 500 MHz*km at 1300 nm, and a loss of 1.5 dB 
    per km at 1300 nm. 
    
    The power budget is 11 dB
