Dual Single-Channel OADMs (CWDM-OADM1-xxxx)
The Dual Single-Channel OADMs (CWDM-OADM1-xxxx) allows you to add/drop two channels of the
same wavelength into the two directions of an optical ring. The other wavelengths are passed through
the OADM. The dual single-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 CWDM GBIC and CWDM SFP
connections. Eight versions of this OADM are available, one for each wavelength of light. (See
The dual single-channel OADMs, shown in Figures
coding of the CWDM GBIC and CWDM SFP transceivers. The dual single-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.
