Extron FOX3 T 321 SM (part number 60-1777-12) — singlemode fiber optic transmitter for DisplayPort video, USB, stereo audio, RS-232, IR and 3D sync.
Where the multimode FOX3 T 321 stops at 500 m, the singlemode build keeps going to 20 km. Extron lists 60-1777-12 as the lossless singlemode version: a DP 1.2a source crosses a single 1310 nm fiber as a mathematically lossless 4096x2160/60 4:4:4 image, and the FOX3 LinkLicense 70-1098-12 later unlocks a fully uncompressed two-fiber link. The 321 also brings a genuine USB 2.0 host port in addition to the HID-only one, so peripherals beyond keyboard and mouse survive the trip.
Key Capabilities
- 20 km (12.4 miles) of singlemode reach at 1310 nm with a +7.4 dB loss budget.
- DP 1.2a input rated 21.6 Gbps overall, 5.4 Gbps per lane, 8 or 10 bits per color.
- USB 2.0 host port at up to 480 Mbps plus a device-class-filtered HID port.
- DisplayPort loop-out drives a local 4K display straight from the transmitter.
- Analog stereo in with -18 dB to +24 dB trim, and an analog stereo return channel.
- RS-232 control and pass-through to 115,200 baud, plus 30-56 kHz IR insertion.
Where It Is Used
Singlemode is what gets specified when the source and the operator are in different buildings: campus data centres feeding remote consoles, airport and rail operations rooms, utility and pipeline SCADA, stadium production, and defence sites where a fiber run is chosen partly because it cannot be tapped inductively.
