DESCRIPTION

The HFM5300 modem can be used for asynchronous

transmission of data and control lines over single optical

fiber. Single fiber communication is achieved by means

of a dual state optoelectronic device which is alternately

switched between transmitt and receive mode by a single

integrated circuit. The modem is designed to operate on

a single fiber as either a true modem, where the hand

shake and control lines are locally interactive (handshake

mode) or as a multiplexer transferring the input states of

both the data and control lines to the far end modem

(data transmission mode). The HFM5300 modem

provides EMI/RFI protection, data security, and

eliminates ground loop and lightning problems.

APPLICATION

The unit can be powered using an SPX5135 power cube,

or through pin 9 of the 25 pin D-connector using +10 V at

50 mA referenced to pin 7, signal ground. Any standard

size multimode simplex fiber optic cable can be used

provided that the optical budget for the cable size chosen

is sufficient. This will depend on the link length and the

number of splices in the cable run. Using 50 micron core

diameter cable, link lengths of 2 km are attainable. The

modem is available with either ST¨ or SMA optical

connectors. Link status is indicated by a bicolour LED on

the end of the modem. This indicator changes from red to

green as synchronisation is achieved. An orange, display

occurs in the transition state.
