Jika anda menyediakan teater rumah, bar bunyi atau stesen permainan, anda mungkin telah menemui port berlabel "Optik", "Toslink" atau "S / PDIF". Kabel yang muat di sini ialah kord optik - yang boleh dipercayai, penyelesaian kesetiaan tinggi untuk menghantar audio digital.

Walaupun kabel HDMI telah menjadi standard untuk video, kord optik tetap menjadi kegemaran untuk audiophiles dan peminat teknologi. Dalam panduan ini, kami memecahkan semua yang anda perlu tahu tentang kord optik, bagaimana ia dibandingkan dengan HDMI, dan bagaimana memilih yang sesuai untuk persediaan anda.

Apakah Kord Optik?

Kord optikal (juga dikenali sebagai kabel audio optikal, Toslink, atau kabel audio gentian optik) ialah sambungan fizikal yang menggunakan denyutan cahaya untuk menghantar isyarat audio digital dari sumber (seperti TV atau konsol permainan) ke penerima (seperti bar bunyi atau penguat).

Tidak seperti wayar tembaga tradisional yang menggunakan elektrik, kord optik menggunakan gentian optik. Reka bentuk yang berbeza ini menawarkan kelebihan yang ketara: imuniti terhadap gangguan.

Bagaimana ia berfungsi

Penghantaran: TV anda menukar isyarat audio elektrik kepada denyutan cahaya.

Perjalanan: Denyutan cahaya ini bergerak melalui helai gentian optik di dalam kord optik.

Penerimaan: Peranti penerima (cth., bar bunyi) menukar denyutan cahaya kembali kepada isyarat elektrik dan memainkan bunyi.

Kord Optik lwn HDMI ARC: Mana Yang Perlu Anda Pilih?

Ini adalah soalan yang paling biasa untuk pengguna teater rumah. Kedua-dua kabel menghantar audio digital, tetapi mereka mempunyai perbezaan yang berbeza.

Ciri
Kord Optik (Toslink)
HDMI ARC / eARC
Kualiti Audio
Menyokong 5.1 termampat (Dolby Digital, DTS)
Menyokong 7.1 yang tidak dimampatkan, Dolby Atmos, DTS: X
Isyarat Video
Tiada (Audio sahaja)
Ya (Audio + Video)
Gangguan
Kekebalan kepada bunyi EMI / RFI
Terdedah kepada gelung / gangguan tanah
Keserasian
Universal (Peranti Lama & Baharu)
Memerlukan port HDMI-CEC / ARC
Ketahanan
Rapuh jika bengkok tajam
Lebih teguh

Keputusan:

Gunakan Kord Optik jika: Anda mempunyai penerima lama yang kekurangan HDMI, anda mengalami hingar "bersenandung" (gelung tanah) dengan persediaan semasa anda atau anda mahukan sambungan audio khusus yang berasingan daripada suapan video anda.

Gunakan HDMI ARC jika: Anda memerlukan sokongan untuk Dolby Atmos, TrueHD atau mahu mengawal TV dan bar bunyi anda dengan satu alat kawalan jauh (CEC).

Faedah Teratas Menggunakan Kord Optik

1. Gangguan Elektromagnet Sifar

Oleh kerana kord optik menghantar cahaya dan bukannya elektrik, ia benar-benar kebal terhadap gangguan elektromagnet (EMI) dan gangguan frekuensi radio (RFI). Ini menjadikan mereka pilihan yang tepat untuk persediaan kompleks dengan banyak kabel kuasa dan peranti wayarles yang mungkin merendahkan kualiti isyarat.

2. Keserasian Luas

Pelabuhan optik adalah ruji dalam dunia teknologi. Anda akan menemuinya di:

TV Pintar (Samsung, LG, Sony, dll.)

Bar Bunyi (Sonos, Bose, JBL)

Konsol Permainan (PS4, Xbox One dan generasi yang lebih lama)

Kad Bunyi PC

Pemain DVD dan Blu-ray

3. Kesetiaan Tinggi Mampu Milik

Anda tidak perlu membelanjakan banyak wang. Malah kord optik yang mesra bajet boleh menyampaikan bunyi digital yang bersih, kerana isyarat digital (cahaya) sama ada tiba di destinasi atau tidak - secara amnya tiada "degradasi" kualiti bunyi seperti dengan kabel analog.

Panduan Membeli: Cara Memilih Kord Optik Terbaik

Tidak semua kord dicipta sama. Apabila membeli-belah di Amazon atau di kedai elektronik, cari tiga ciri ini:

Muat Penyambung (Toslink): Pastikan penyambungnya kukuh. Petua bersalut emas popular, bukan untuk kekonduksian (kerana ia menggunakan cahaya), tetapi kerana ia menahan kakisan dan melindungi hujung gentian.

Jaket Kabel & Ketahanan: Gentian optik adalah kaca atau plastik dan boleh pecah jika dibengkokkan. Cari kord optik dengan jaket nilon berjalin atau PVC tebal, yang menghalang kekusutan dan melindungi teras yang halus.

Panjang: Isyarat cahaya boleh lemah pada jarak yang sangat jauh. Cuba lekat pada kord di bawah 15 hingga 30 kaki (5 hingga 10 meter). Jika anda memerlukan jangka masa yang lebih lama, pastikan anda membeli kabel teras kaca berkualiti tinggi dan bukannya kabel plastik.

Cara Menyambung Kord Optik dalam 3 Langkah

Penyediaan adalah pasang dan main, tetapi terdapat satu kesilapan biasa yang dilakukan oleh orang ramai.

Tanggalkan Penutup: Penting! Kord optik baharu disertakan dengan penutup plastik kecil pada hujung untuk melindungi kanta. Tanggalkan penutup ini sebelum cuba memasangkannya, atau anda mungkin merosakkan port anda.

Masukkan Teguh: Palamkan satu hujung ke dalam "Audio Digital Keluar" (Optik) pada TV anda dan satu lagi ke dalam "Audio Digital Masuk" pada bar bunyi anda. Anda sepatutnya berasa memuaskan
click.

Tukar Tetapan TV: Pergi ke tetapan audio TV anda. Tukar "Keluaran Bunyi" kepada Optik atau Audio Keluar.

Petua Pro:
Jika anda tidak mendengar bunyi, tukar "Format Audio Keluaran Digital" daripada Auto kepada PCM atau Bitstream.

Soalan Lazim: Soalan Lazim Mengenai Kord Optik

S: Bolehkah kord optik menghantar Dolby Atmos?

J: Secara amnya, tidak. Sambungan optik terhad kepada bunyi sekeliling 5.1 yang dimampatkan (seperti Dolby Digital standard). Untuk format lebar jalur tinggi seperti Dolby Atmos atau Audio Induk DTS-HD, anda memerlukan HDMI eARC.

S: Mengapa ada lampu merah keluar dari kord optik saya?

A: Itulah isyarat audio! Lampu merah ialah gelombang pembawa untuk data digital anda. Jika anda melihat cahaya di hujung kabel, ini bermakna peranti sumber berfungsi dengan betul.

S: Adakah kord optik yang mahal berbaloi?

J: Untuk jarak pendek (di bawah 6 kaki), kord gentian plastik murah berfungsi sama seperti yang mahal. Untuk larian yang lebih lama, melabur dalam kord berkualiti tinggi dengan teras kaca boleh menghalang keciciran isyarat.

Langkah Seterusnya

Periksa bahagian belakang TV dan bar bunyi anda hari ini. Jika anda sedang menggunakan kabel analog merah-putih (RCA), beralih kepada kord optik ialah satu-satunya peningkatan termurah yang boleh anda buat untuk meningkatkan kejelasan bunyi anda dengan serta-merta.
