Two USB type-A HID ports extend keyboard, mouse, and other HID-class peripherals back to the source, with device class filtering fixed at the factory so the port cannot be reconfigured for mass storage or other USB classes in the field. Configuration runs through a front panel USB-B port over Ethernet-over-USB, and the rear RJ-45 Ethernet port supports full monitoring and control using Extron SIS commands or Extron Product Configuration Software. This lossless variant uses 1 SFP (mathematically lossless 4K\/60 over one fiber), giving a maximum channel data rate of 10.0 Gbps (1 fiber).\u003c\/p\u003e\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRecovers 4K\/60 4:4:4 HDMI video, stereo audio, and USB HID over fiber\u003c\/li\u003e\n\u003cli\u003e500 m (1640 feet) on multimode fiber\u003c\/li\u003e\n\u003cli\u003eBidirectional RS-232 and IR pass-through control\u003c\/li\u003e\n\u003cli\u003eDevice class filtering locks USB ports to HID for secure environments\u003c\/li\u003e\n\u003cli\u003eHalf-rack metal enclosure with optional rack shelf or under-desk mount\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eKVM extension for secure workstations, command centers, and control rooms that need HDMI, HID peripherals, and RS-232\/IR device control delivered together over a single fiber run specify the R 311 alongside a matching FOX3 T 311 transmitter or FOX3 Matrix frame.\u003c\/p\u003e\n\u003ch3\u003eSpecifications at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOptical link: 1 SFP (mathematically lossless 4K\/60 over one fiber), 1 LC connector, 500 m (1640 feet)\u003c\/li\u003e\n\u003cli\u003eVideo output: 1 HDMI, up to 4096x2160 at 60 Hz 4:4:4\u003c\/li\u003e\n\u003cli\u003eEnclosure: 1.7\" H x 8.75\" W x 8.5\" D (half rack wide)\u003c\/li\u003e\n\u003cli\u003ePower: internal 100-240 VAC, 24.4 W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"alt-refs\"\u003eAlso referenced as Extron FOX3R311MM, FOX3-R-311-MM, part number 60152321.\u003c\/p\u003e","brand":"Extron","offers":[{"title":"Default Title","offer_id":52302265385180,"sku":"EXTRON-FOX3R311MM-60152321","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/5582\/4092\/files\/extron-fox3-r-311-mm-60-1523-21.jpg?v=1787221486","url":"https:\/\/www.ampronix.com\/products\/extron-fox3-r-311-mm-60-1523-21","provider":"Ampronix","version":"1.0","type":"link"}
