Optical isolation is a great way to eliminate conducted noise along copper cables. It will not, of course, eliminate noise that modifies the signal (i.e. distortion), but stray electrical and induced RF interference is a huge source of degradation of your musical playback. \u003c\/p\u003e\n\u003cp\u003eThe RSA720 has four independent USB ports to connect a variety of devices simultaneously and is carefully designed to offer stable, high-speed data transmission. \u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eIncluded Accessories\u003c\/h3\u003e\n\u003cp\u003eIncludes a USB Cable, Ethernet Cable, and Optical SFP Modules for a complete setup experience.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSP module x 2\u003c\/li\u003e\n\u003cli\u003eSFP LC cable 1m\u003c\/li\u003e\n\u003cli\u003eUSB 3.0 type B cable 1m\u003c\/li\u003e\n\u003cli\u003eAdaptor\u003c\/li\u003e\n\u003cli\u003eAC power cord\u003c\/li\u003e\n\u003cli\u003eManual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eInputs:\u003c\/strong\u003e USB 3.0 Type B, USB 3.0, 10G SFP\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutputs:\u003c\/strong\u003e USB 2.0 Type B, SFP\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower:\u003c\/strong\u003e DC 12 V, 3 A\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (WDH):\u003c\/strong\u003e 5.98\" x 6.04\" x 1.32\"\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.65 lb.\u003cbr\u003e\u003c\/p\u003e","brand":"HiFi Rose","offers":[{"title":"Default Title","offer_id":42893874823352,"sku":"HFR-RSA720","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/files\/HROSRSA720A_StockPhoto_Front.jpg?v=1741629949","url":"https:\/\/upscaleaudio.pro\/products\/hifi-rose-rsa720-optical-usb-hub","provider":"Upscale Audio","version":"1.0","type":"link"}
