Cisco CWDM-MUX-AD-1590 Dual single-channel OADM (1590 nm) CWDM-MUX-AD-1590
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 GBICs on the equipment side. All the modules are the same size. The CWDM 2-slot chassis allows you to rack mount up to two CWDM OADMs in a single rack unit. There are four different types of CWDM OADMs:
Dual Single-Channel OADMs (CWDM-MUX-AD-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. Dual fiber is used for both the network and the CWDM GBIC connections. Eight versions of this OADM are available, one for each wavelength of light. The dual single-channel OADMs are color coded and match the color coding of the CWDM GBICs.
