KEY FEATURES AND BENEFITS
Features and Benefits
The Cisco WDM series of CWDM devices offer numerous improvements over the previous generation of devices:
1.
Lowest optical insertion loss (refer to Table 2 for details)—Compared to the previous generation of CWDM filters, the insertion loss is reduced
up to 50 percent, depending on the model. This translates into much longer distances in both point-to-point and ring configurations.
2.
Addition of “monitor” ports on every network port of multiplexers and OADMs as well as on the pass port on OADM4-x to simplify turn-up
operations of CWDM networks—The monitor ports also can be used for in-service monitoring of the CWDM signals by means of an optical
spectrum analyzer or a power meter.
3.
Addition of two 4-channel OADM types for added flexibility: part number CWDM-OADM4-1 to cover the 1470, 1490, 1510, and 1530
channels and part number CWDM-OADM4-2 to cover the 1550, 1570, 1590, and 1610 channels.
4.
LC/UPC connectors
5.
1300-nm transparency—OADMs are now transparent to “traditional” 1300-nm channels. In other words, the 1300-nm signals can pass through
the OADMs with a well-controlled loss. This feature helps enable configurations where CWDM can share the same fiber with traditional
SONET/SDH services running on the 1300-nm wavelength.
6.
Addition of a WDM splitter (or Y-cable) to multiplexer and demultiplexer channels in the 1300- and 1550-nm ranges—The WDM splitter cable
can be used with CWDM optics or with standard 1550 optics. This Y-cable is another tool to integrate on the same fiber infrastructure CWDM
with traditional SONET/SDH services running on the 1300-nm wavelength.
