Details

Extron FOX3 T 331 SM (part number 60-1778-12) — a singlemode fiber transmitter for DisplayPort video, USB HID, stereo audio, and RS-232/IR control, factory-configured for uncompressed transmission over two fibers.

This half-rack transmitter accepts a DisplayPort source, a discrete analog or embedded stereo audio input, and a single USB HID connection, then sends the combined signal out over two singlemode fibers at up to 4096x2160 at 60 Hz, 4:4:4, bit-for-bit uncompressed, with reach to 20 km at 1310 nm.

Key Capabilities

Uncompressed 4096x2160 at 60 Hz, 4:4:4 DisplayPort 1.2a transmission over two fibers
Singlemode fiber reach to 20 km (12.4 miles) over LC connectors
Dedicated USB HID port for keyboard, mouse, and touch-panel extension
Discrete or DisplayPort-embedded stereo audio input with adjustable gain and audio return
RS-232 and IR insertion plus DisplayPort loop-out for local monitoring
Half-rack metal enclosure backed by a 3-year Extron warranty and 7-year Everlast PSU coverage

Where It Is Used

Fits secure operations centers, command rooms, and broadcast facilities needing an uncompressed DisplayPort link over long singlemode runs with locked-down USB peripheral support.
