CWDM-OADM1-1530 Cisco Dual Single Channel OADM Module

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.
