We have several types of fiber can be used for Toslink: inexpensive 1 mm plastic

optical fiber, higher-quality multistrand plastic optical fibers, or quartz glass optical

fibers, depending on the desired bandwidth and application. Toslink cables are usually
limited to 5 meters in length, with a technical maximum of 10 meters, for reliable

transmission without the use of a signal booster. However, it is very common for

interfaces on newer consumer electronics (satellite receivers and PCs with optical

outputs) to easily run over 30 meters on even low-cost ($0.75/m) Toslink cables.

Toslink transmitters operate at a nominal optical wavelength of 650 nm(~461.2 THz).
