RAD Data Communications 2006 Catalog

Transmission over fiber ensures data

integrity, high immunity against EMI/RFI and

data security. The modem supports ranges

of up to 3 km (1.9 miles) over multimode

fiber and up to 16 km (10 miles) over single

mode fiber.

End-to-end signaling is available using the

carrier between the modems in controlled

carrier mode. When RTS is raised on one

end, it causes the DCD to rise on the other

end of the link.

Innovative circuitry allows the modems to

operate without external power, by drawing

low power from the DTE data and control

signals.

The FOM-6AV has a V.24/RS-232 interface

and is available with either a male or female

integral D-type 25-pin connector.

The product includes an LED for indicating

data transmission over the link.

The modem is available in a metal casing

(ordering option) to increase data

transmission security and EMI/RFI immunity.

The miniature FOM-6AV high speed fiber optic modem

is used for transmission of asynchronous data over

fiber optic links. It operates at any data rate up to

57.6 kbps and supports any type of asynchronous

characters with no need for configuration. 

FOM-5A and FOM-6A are miniature fiber

optic modems used for local data

distribution, connecting full or half duplex

async computers and terminals. A pair of

modems ensures integrity of data

transmission over multimode fiber optic

cables for distances up to 3 km (1.9 miles)

at data rates up to 19.2 kbps. 

The FOM-5A is a sub-miniature version of

the FOM-6A, offering all the features in half

the size. 

Innovative circuitry allows the modems to

operate without external power, by drawing

low power from the DTE data and control

signals.

The FOM-5A and FOM-6A have a V.24/RS-232

interface and are available with either a male

or female integral 25-pin connector.

The modem is available as a card for 

mounting in a 19" rack (see the CMN-16

nest, card CMN-CF6A).
