Details

Extron FOX3 SR 311 SM (part number 60-1732-24) — a singlemode fiber optic receiver built for uncompressed 4K/60 HDMI delivery across long campus and facility runs.

This receiver pulls the video, audio, USB HID, and control signals sent by a matching FOX3 transmitter and rebuilds them at the display end. Its onboard scaler outputs up to 4096x2160 at 60 Hz with 4:4:4 color, so a single receiver can match whatever native resolution a downstream display needs regardless of what the source is putting out. Because it rides on singlemode glass at 1310 nm, reach extends to 20 km — enough to link buildings on a campus or bridge a stadium concourse — without the signal loss copper-based extenders suffer over distance.

Key Capabilities

Rebuilds HDMI up to 4096x2160 at 60 Hz, 4:4:4 chroma, from incoming fiber data
Singlemode fiber reach to 20 km (12.4 miles) over LC connectors
USB HID pass-through for KVM-style keyboard and mouse extension
Analog stereo audio de-embed plus a return audio channel for local mic or paging
RS-232 and IR insertion ports keep sources and displays controllable at distance
Front-panel Ethernet-over-USB configuration port and rear RJ-45 for network monitoring

Where It Is Used

Pairs naturally with a FOX3 T 311 transmitter for point-to-point 4K delivery, or with a FOX3 matrix for enterprise distribution. The long singlemode reach suits university campuses, airports, stadiums, and government or medical sites where runs exceed what copper HDBaseT extenders can cover and a secure, interference-immune link matters.
