The OPM-300 series features metal headshells, metal guides, and heavy-duty outer jacketing. For use with ADATs and other Toslink-equiped recording gear.

TOSLINK is a standardized optical fiber connection system. Its most common use is in consumer audio equipment (via a "digital optical" socket), where it carries a digital audio stream between components such as MiniDisc and CD players and DAT recorders. TOSLINK may use 1 mm plastic optical fiber or it can use higher quality multi-strand plastic optical fibers or even quartz glass optical fibers depending on the desired bandwidth and application.

TOSLINK was originally created by Toshiba to connect their CD players to their receivers for PCM audio streams, but it was adopted for most CD players, regardless of manufacturer. Early TOSLINK systems used raw data from the CD player, but the S/PDIF standard has now become fairly universal for audio streams. It can often be found on DVD players and some game consoles to connect the digital audio stream to Dolby Digital/DTS decoders.

TOSLINK has many applications, using several different connector types. However, audio connections using the EIAJ/JEITA RC-5720 (also CP-1201 and JIS C5974-1993 F05) connector are by far the most common.

TOSLINK Signal cables must be limited to below 10 meters or, in many cases, under 5 for reliable transmission unless using a signal booster.

The real benefit to optical fiber for audio is that it is not susceptible to line noise or other electromagnetic interference.

Because of the fragile nature of TOSLINK cables - we are unable to offer a Lifetime warranty.  You will get immaculate sound - but you need to handle these cables with some care.
