Unlike its SR 321 sibling, the SR 331 keeps the USB side dedicated to HID peripherals only — keyboards, mice, and touch controllers — rather than general USB 2.0 devices, which simplifies KVM deployments where a stray USB device shouldn't be extendable. Running lossless mode over a single fiber, it targets workstations where compression is not an option.\u003c\/p\u003e\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLossless 4096x2160 at 60 Hz, 4:4:4 DisplayPort output over one multimode fiber\u003c\/li\u003e\n\u003cli\u003eMultimode reach to 500 m (1640 ft) on OM4 laser-optimized cable\u003c\/li\u003e\n\u003cli\u003e2-port USB HID extension for keyboard, mouse, and touch control\u003c\/li\u003e\n\u003cli\u003eRS-232 and IR insertion for remote source and display control\u003c\/li\u003e\n\u003cli\u003eAnalog stereo audio de-embed with a local audio return channel\u003c\/li\u003e\n\u003cli\u003eFront-panel USB configuration port and rear RJ-45 for Ethernet monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eBuilt for KVM-style DisplayPort workstation extension in control rooms, trading desks, and secure facilities where only HID peripherals — not general USB storage or cameras — should be able to reach the source.\u003c\/p\u003e\n\u003ch3\u003eSpecifications at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVideo: DisplayPort 1.2a, up to 4096x2160 at 60 Hz, 4:4:4, 21.6 Gbps\u003c\/li\u003e\n\u003cli\u003eFiber: multimode, 500 m max reach, 2 or 4 LC connectors, 850 nm\u003c\/li\u003e\n\u003cli\u003eUSB: 2-port USB HID only, 100 mA available\u003c\/li\u003e\n\u003cli\u003eEnclosure: half-rack metal, 1.7\"H x 8.75\"W x 8.5\"D, 2.4 lbs\u003c\/li\u003e\n\u003cli\u003ePower: internal 100-240 VAC supply, 26.1 W consumption\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"alt-refs\"\u003eAlso referenced as Extron FOX3SR331MM, FOX3-SR-331-MM, part number 60177821.\u003c\/p\u003e","brand":"Extron","offers":[{"title":"Default Title","offer_id":52302280786140,"sku":"EXTRON-FOX3SR331MM-60177821","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/5582\/4092\/files\/extron-fox3-sr-331-mm-60-1778-21.jpg?v=1787221614","url":"https:\/\/www.ampronix.com\/products\/extron-fox3-sr-331-mm-60-1778-21","provider":"Ampronix","version":"1.0","type":"link"}
