Fiber Cable Transmission Modes

Two versions of non‑pathologically‑compliant FOX matrix switcher fiber optic I/O board are
documented in this guide. They are categorized by the type of fiber optic cable, multimode
or singlemode, which defines the effective range of transmission:

Features

Fiber optic inputs and outputs — With fiber optic I/O boards, the switchers input and
output fiber optic signals on SFP optical connectors. The fiber optic I/O boards support
digital signals from 270 Mbs through 4.25 Gbps.
SDI, HD-SDI, or 3G-SDI inputs and outputs — With SDI/HD‑SDI I/O boards,
the switchers input and output SDI and HD‑SDI signals on BNC connectors. The
SDI/HD‑SDI I/O boards support multi‑rate SDI at rates up to 2.97 Gbps, and comply with
SMPTE 259M‑C, 292M, 424M, and ITU digital video standards.
Cross-format compatibility —
•
•
Switching flexibility — The switcher provides individually buffered, independent matrix
switched outputs.
•
•
Input link detection — In critical environments or unmanned, remote locations, it may be
vital to know that sources are active and switching. The switcher confirms that input sources
are active by detecting light. Link detection provides instantaneous feedback via the serial
ports or LAN port of the switcher. The input information can be displayed on any control
system or in a Windows‑based control program on a local‑area network (LAN) or Internet
(IP) connection.
Rooming — The switcher can be programmed to group multiple outputs to specific
"rooms", allowing them to have their own presets.
Multimode — Long distance, up to 300 m (985 feet)
Singlemode — Very long distance, up to 30 km (18.75 miles)
• All transceiver modules on a fiber optic I/O board, as delivered from Extron, are
configured the same; either all multimode or all singlemode.
•
You can mix multimode and singlemode fiber optic I/O boards in a FOX matrix
switcher, but you must ensure that you connect the proper transmission mode fiber
cables to the board.
An input on an SDI/HD‑SDI I/O board can be tied to an output on a fiber optic I/O
board.
An input on a fiber optic I/O board can be tied to an output on an SDI/HD‑SDI I/O
board.
Tie any input to any or all outputs.
Quick multiple tie — Multiple inputs can be switched to multiple outputs
simultaneously. This allows all displays (outputs) to change from source to source at the
same time.
