you could make one perhaps? looks like a TOSLINK module and a linear regulator with a coupling capaitor and input output capacitors for the regulator. I would guess the pins on the connector are: SPDIF data, GND, GND, 5V? (not necessarily in that order) .
It looks like I might have to have a go at making one. The Twisted Pear module used a Toshiba Optical receiver socket that needed 3.3v. I will use a Cliff socket that needs 5v which I will have in the case for another module and so a regulator will not be needed.
This will be my first dip into an Optical to consumer level spidf conversion. The circuit must be pretty simple but can someone kindly draw it out for me? Thanks.

I've now found some more information.
The Twisted Pear website says that the supply voltage to the module can be 5-12v. The voltage regulator on the module is a 3.3v one. The Toshiba TORX 147LF SPDIF socket used on the module needs, according to the data sheet, 2.7-3.6v, hence the 3.3v regulator.
The Toshiba TORX 147LF SPDIF socket now appears to be discontinued. A suitable alternative is made by Cliff Electronic Components Ltd in the UK and will operate on up to 7v. Hence my comment about not needing a regulator if 5v is available.

Toslink to line level converters are all over ebay here. I paid $11 for mine. Warning, do not kill the TV commercials by unplugging the power supply to the module. It causes the power supply to rattle at twice the AC line frequency when plugged back in. **** switcher supplies.
Warning, it took 4 days for me to gather enough strength to plug in the fiber cable. I had to use enough force that would have broken a stereo 1/8" phone plug. I had permission to send it back, but kept it after I got it working.
