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 Figure 2 and Figure 3, 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.
