Fiber cable transmission modes

Two versions of Fiber Matrix switcher fiber optic I/O boards are documented in

this manual. They are categorized by the type of fiber optic cable, multimode or

singlemode, which defines the effective range of transmission:

Multimode — Long distance, up to 300 m (985')
Singlemode — Very long distance, up to 30 km (18.75 miles)
N

All transceiver modules on a fiber optic I/O board, as delivered from Extron, are

configured the same; either all multimode or all singlemode.

N

You can mix multimode and singlemode fiber optic I/O boards in a Fiber Matrix

switcher, but you must ensure that you connect the proper transmission mode
fiber cables to the board.

Definitions

The following terms, which apply to all Extron matrix switchers, are used

throughout this manual:

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

memory presets can be stored in memory. When a preset is retrieved from

memory, it becomes the current configuration. Presets can be saved and

recalled from the front panel and any of the serial or LAN ports. For front

panel operations, preset locations are assigned to the input buttons.

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

have up to 10 presets.

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.

Features

Fiber optic inputs and outputs —

With fiber optic I/O boards, the switchers input

and output fiber optic signals on 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 —
• 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.
