CWDM OADMs

The CWDM OADMs are passive devices that can multiplex/demultiplex or add/drop wavelengths from

multiple fibers onto one optical fiber. The OADM connectors are interfaced to the color-matching

CWDM GBIC or CWDM SFP transceivers on the equipment side. All OADMs are the same size. Two

OADM modules can be installed in a CWDM 2-slot chassis (CWDM-CHASSIS-2). There are three

different types of CWDM OADM modules

8-Channel Multiplexer/Demultiplexer (CWDM-MUX-8A=)

The 8-Channel Multiplexer/Demultiplexer (CWDM-MUX-8A=) allows you to multiplex/demultiplex

eight separate channels into one pair of fiber. Dual fiber is used for both the network connection and the

CWDM GBIC or CWDM SFP transceiver connections. The eight available wavelengths are 1470-nm,

1490-nm, 1510-nm, 1530-nm, 1550-nm, 1570-nm, 1590-nm, and 1610-nm. The

multiplexer/demultiplexer, shown in

a power meter or an optical spectrum analyzer to assist you in monitoring and troubleshooting the

network.

4-Channel OADM (CWDM-OADM4-1= and CWDM-OADM4-2=)

The 4-Channel OADM (CWDM-OADM4-1= and CWDM-OADM4-2=) allows you to add/drop four

channels (with different wavelengths) into one direction of an optical ring. The other wavelengths are

passed through the OADM. The 4-channel OADMs are transparent to the 1300-nm wavelength and

includes a 1300-nm/1500-nm filter to mix legacy SONET/SDH/ATM ring installations with CWDM

installations on the same optical fiber. Dual fiber is used for both the network and the GBIC or SFP

connections. The two 4-channel OADMs, shown in

wavelengths:

The 4-channel OADM modules are equipped with a monitor port that allows you to attach a power meter

or an optical spectrum analyzer to assist you in monitoring and troubleshooting the network.
