GENERAL DESCRIPTION
The OFM-4218 is coarse wave division optical wavelength division multiplexer / demultiplexer (CWDM) for
combining and separating up to eighteen optical signals of 1270nm, 1290nm, 1310nm, 1330nm, 1350nm, 1370nm,
1390nm, 1410nm, 1430nm, 1450nm, 1470nm, 1490nm, 1510nm, 1530nm, 1550nm, 1570nm, 1590nm and
1610nm wavelengths for either uni-directional or bi-directional transmission on the one fibre.
With the high cost of hiring or installing additional dark fibre it makes economical sense to maximise the use of
existing infrastructure.
Used in combination with IRT’s extensive range of fibre transmitters / receivers and interface modules, a myriad of
different signals types can be sent down the one fibre. With IRT’s eighteen channel fibre multiplexer/demultiplexer
modules, for example, up to 144 SDI signals can be sent down a single fibre. Or up to 576 ASI signals can be sent
when also used with IRT’s ASI multiplexer/demultiplexer modules.
The OFM-4218 is designed to mount in IRT’s 1RU or 4000 series 3RU frame.
Standard features:
•
Eighteen set CWDM optical wavelength inputs and outputs.
•
Uni-directional or bi-directional operation.
•
Low insertion loss.
•
Connections made by LC/PC and SC/PC connectors.
