1. Nhanganyaya
Unogona kuona chiteshi che "Optical" kana "Digital Audio Out" kuseri kweTV yako, soundbar, kana AV inogamuchira wofunga kuti ingori imwe yekuisa. Asi kuziva zvinoitwa netambo yemaziso inogona kukuchengetedza kubva pakugumburisa kudonhedza-outout, pasi-loop hum, uye kuwirirana kwemusoro-kunyanya kana uchibatanidza zviratidziro zvemazuva ano negiya redhiyo regiya kana kufambisa ruzha-isina ruzha mumaseta akaomarara emitambo yemitambo.
Tambo yekuona, inowanzonzi TOSLINK (Toshiba Link) kana tambo yedigital optical, inotumira odhiyo semhepo yechiedza che infrared kwete masaini emagetsi. Kuchinja kuri nyore uku kunobvisa kupindira kwese, kunoita kuti ruzivo rwako rwekuteerera rurambe rwakachena, uye runowedzera kupfuura mutengi-giredhi redhiyo kuita data-center interconnects, Broadband "yekupedzisira mamaira" kuendesa, uye chaiyo maindasitiri sensors.
Chinyorwa ichi chinoongorora:
● Chii chinonzi optical cord uye kwayakabva
● Iyo inoshanda sei kutakura audio
● Mabhenefiti akakosha pane mamwe marudzi etambo
● Chaiyo-yepasirese yekushandisa makesi mudzimba dzemitambo, networking, Broadband, uye zvekurapa/maindasitiri minda
● Side-ne-parutivi kuenzanisa neHDMI ARC/eARC, coaxial digitaalinen, uye analog tambo.
● Nzira yekusarudza, kuisa, uye kugadzirisa tambo dzemaziso
● Kusimukira maitiro anozogadzira ramangwana refiber-optic links
Pakupedzisira, iwe unonzwisisa zvinoitwa netambo yemaziso, nguva yekushandisa imwe, uye nzira yekutora tambo yakakodzera kune chero application.

 
2. Chii chinonzi Optical Cord?
Tambo yemaziso-inozivikanwawo sea digital optical cable kana TOSLINK-itambo inotakura dhijitari redhiyo data kuburikidza nemwenje pulses kuburikidza nefiber yakatetepa. Kusiyana netambo dzakagadzirwa nemhangura, inoshandisa ingave girazi kana purasitiki fiber kuendesa ruzivo, zvichiita kuti ive 100% isingadzivirirwe kune electromagnetic interference (EMI) uye pasi-loop hum yakajairika nemagetsi.
Yakatangwa naToshiba muna 1983 kubatanidza vatambi veCD kune vanogashira, TOSLINK mwero wakazove nzira yekubatanidza maodhiyo evatengi. Nekufamba kwenguva, chimiro chechimiro chakashanduka kuita Mini-TOSLINK (3.5 mm plug yemalaptops nemidziyo inotakurika) uye yakaderera-mutengo epurasitiki optical fiber (POF) akasiyana ekushandisa bhajeti-ane hushamwari uye mapfupi anomhanya.
2.1 Terminology
