Source for Toslink xmit connector

[Robert E. Griffith]

Does anyone know where to get toslink optical digital audio output connectors from?   Googling reveled a Toshiba part TOTX173, and a sharp part GP1F32T, but I have not found a source where I can get them.  I need a couple of parts now, and then 100 at a time.   Thanks,   --BobG
