I had trouble with the return path so I posted instead. I have a fiber optic
ethernet transceiver on my desk. It is made by Codenoll and the model number
is 3030C. I took this device apart and found the following:

	A big 30 pin device labeled "CODELINK 20BR OPTICAL RECEIVER"
	A big 20 pin device labeled "CODELINK 20BT OPTICAL TRANSMITTER"
	About 14 DIP IC's (MC10116, MC10117, TC74123, MC74132, CD74165)
	An interesting board with 5 chips thats been dipped in a black coating

This device uses multimode fiber (not single mode like you specified). You
can purchase these, I'm sure, but I do not know if Codenoll will sell the
individual transmitter and receiver units inside their transceivers. The cost
(about a year ago) was $795 per transceiver.

Should you wish to contact them, their address is as follows:

	Codenoll Technology Corporation
	1086 North Broadway
	Younkers, NY 10701
	USA
	Tel: (914) 965-6300


Hope this was helpful.
