PCOM-3211 series CWDM optical multiplexers/demultiplexers with 4/8/16 wavelengths support

PCOM-3211-4/8/16 series CWDM (Coarse Wavelength Division Multiplexing) optical multiplexers/demultiplexers provide the wavelength selectivity in the CWDM optical band (1270~1610nm): 1270±2nm, 1290±2nm, 1310±2nm, 1330±2nm, 1350±2nm, 1410±2nm, 1430±2nm, 1450±2nm, 1470±2nm, 1490±2nm, 1510±2nm, 1530±2nm, 1550±2nm, 1570±2nm, 1590±2nm, 1610±2nm.

PCOM-3211 is passive device, both the wavelength separation and combining are possible.

PCOM-3211 CWDM modifications with the 1470nm and 1550nm boundary wavelengths are fitted with the broadband (1260~1360nm) expantion input. An intended connection is the 4-channel CWDM multiplexer's output with the 1270nm boundary wavelength or 1310nm optical output of any device.

General description

A 4-channel CWDM optical system consists of a pair of PCOM-3211-4 units, one is an optical multiplexer, the other - as a demultiplexer.

The "2-2" type bidirectional optical system:

The "1-3" type bidirectional optical system:

An example of the extention input usage:

An eight-channel and a sixteen-channel system may be implemented in a similar way.
