Cisco Cisco DWDM Transceiver Modules 설치 가이드

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

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 

, is 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.

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 

, support the following 

wavelengths:

CWDM-OADM4-1—1470-nm, 1490-nm, 1510-nm, and 1530-nm. 

CWDM-OADM4-2—1550-nm, 1570-nm, 1590-nm, and 1610-nm. 

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.
