Fiber Cable Transmission Modes

Two versions of the 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

•
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 ensure that you connect the proper transmission mode
fiber cables to the board.
Tie — An input-to-output connection.
Set of ties — An input tied to two or more outputs. (An output can never be tied to
more than one input.)
Configuration — One or more ties or one or more sets of ties.
Current configuration — The configuration that is currently active in the switcher (also
called "configuration 0").
Global memory preset — A configuration that has been stored. Up to 64 global
presets can be stored in memory. When a preset is retrieved from memory, it becomes
the current configuration. Presets can be saved and recalled via any of the serial ports
or the LAN port.
Room — A subset of outputs that are logically related to each other, as determined by
the operator. The switchers support up to 10 rooms, each of which can consist of from
1 to 16 outputs.
Room memory preset — A configuration consisting of outputs in a single room that
has been stored. When a room preset is retrieved from memory, it becomes the current
configuration. Up to 10 room presets can be associated with a room.
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 3G/SDI/HD-SDI I/O boards,
the switchers input and output SDI and HD-SDI signals on BNC connectors. The
3G/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 —
An input on an 3G/SDI/HD-SDI I/O board can be tied to an output on a fiber optic

I/O board or another 3G/SDI/HD-SDI I/O board.
An input on a fiber optic I/O board can be tied to an output on an 3G/SDI/HD-SDI
•
I/O board or another fiber optic I/O board.
