Details
Extron FOX3 T 331 MM (part number 60-1778-11) — multimode fiber optic transmitter for DisplayPort video, USB HID, stereo audio, RS-232, IR and 3D sync.
The FOX3 T 331 MM is the security-minded member of the FOX3 DisplayPort family. Its single USB host port is restricted by device class filtering to HID devices only, so a keyboard and mouse can cross the link while mass storage and other classes cannot. Extron lists 60-1778-11 as the lossless multimode build: one 850 nm fiber carries a mathematically lossless 4096x2160/60 4:4:4 image, and adding LinkLicense 70-1098-11 opens two-fiber uncompressed transport. DisplayPort loop-out, EDID Minder, internal test patterns and Ethernet monitoring are all built in.
Key Capabilities
- HID-only USB extension for environments where removable media must not travel.
- DP 1.2a at 21.6 Gbps total and 5.4 Gbps per lane, 8 or 10 bits per color.
- 500 m (1640 feet) over 50 um OM4 multimode fiber, with a +9.7 dB loss budget.
- DisplayPort loop-out for a local 4K monitor plus built-in alignment test patterns.
- Balanced or unbalanced stereo input with -18 dB to +24 dB gain trim, 48 kHz sampling.
- RS-232 control and pass-through plus a 30 kHz to 56 kHz IR insertion port.
Where It Is Used
HID-only extension is written into specifications for classified and defence workstations, financial trading and dealing rooms, hospital clinical networks and utility control centres, where the fiber has to move a picture and a keyboard but nothing else. Multimode keeps the plant affordable across a single building or campus block.
