1206.0. "Low power optics a standard?" by VAXRIO::ROLF (Vaporware Design Specialist) Thu Jan 13 1994 10:07

    Could someone tell me if our LOW POWER solution in the DECconc500 is 
    based on some standard or if it is simply a DEC propriatory technology?
    
    I would like to use the -LA boards, but the customer specifies that
    everything offered relating to PMD should comply with standards:
    
    X3.166-1990 and ISO 9314-3;1990
    
    Thanks 
    
    Rolf, DEC Brazil

	That specific standard is the ANSI MIC (full power multimode) PMD. So the -LA cannot be used if the customer meant precisely what he said. If what he meant was "any of the various ANSI PMD standards", that's a different question. Full power multimode and single mode are approved standards. TP-PMD and low power optics are both drafts. The -LA was developed before the low power work even started in ANSI, but as far as I know it is compatible with the draft standard. Maybe Dick Kirk has a more authoritative answer? paul
