GENERAL:

The OFM-4264 is coarse wave division optical wavelength division multiplexer / demultiplexer (CWDM) for combining and separating up to four optical signals of 1510nm, 1530nm, 1550nm and 1570nm 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 four channel fibre multiplexer/demultiplexer modules, for example, up to sixteen SDI signals can be sent down a single fibre. Or up to sixty-four ASI signals can be sent when also used with IRT's ASI multiplexer/demultiplexer modules.

The OFM-4264 is designed to mount in IRT's 1RU or 4000 series 3RU frame.
