• Two 4-channel OADMs
• One 8-channel multiplexer/demultiplexer
• CWDM SFP transceivers (1470, 1490, 1510, 1530, 1550, 1570, 1590, 1610 nm)
The 1 Gb/s or 2 Gb/s CWDM solution includes the following components:
• A 2-slot chassis for OADM CWDM multiplexer modules, which have the following components:
• Eight 1-channel OADMs
• Two 4-channel OADMs
• One 8-channel multiplexer/demultiplexer
• CWDM SFP transceivers (1470, 1490, 1510, 1530, 1550, 1570, 1590, 1610 nm)
A typical CWDM SFP transceiver installation includes:
• Two multiplexers/demultiplexers or two OADMs
• Up to eight matched pairs of CWDM SFP transceivers of the same frequency
• Up to eight single-mode fiber optic cables
• One long-distance, single-mode fiber optic cable

NOTE:
The HP CWDM multiplexer solution is not supported on B-series, H-series, or M-series switches.
See “Certified third-party WDM, iFCP, and SONET products” on page 352 for more information about
B-series, M-series, and C-series supported WDM devices.
Third-party WDM products
HP supports third-party WDM products that have been tested successfully with a wide range of HP
products (see “Certified third-party WDM, iFCP, and SONET products” on page 352).
Figure 79 and Figure 80 show basic WDM SAN configuration options for typical HP Continuous
Access storage systems. See the Continuous Access EVA XP Continuous Access product documentation
for specific configuration options.
