HP Mainframe Connectivity Design Guide

are networked using a variety of wavelength-specific multiplexers/demultiplexers or OADMs that
support ring or point-to-point topologies.
The 4 Gb/s CWDM solution includes the following components:
• A 2-slot chassis for CWDM multiplexer modules
• 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
For more information, see the C-series Coarse Wave Division Multiplexer product documentation
at http://h18006.www1.hp.com/products/storageworks/cwdm/index.html.
NOTE: The HP CWDM multiplexer solution is not supported on B-series or McDATA switches.
For more information about B-series, McDATA, and C-series supported WDM devices, see “Certified
third-party WDM products” (page 152).
Third-party WDM products
HP supports third-party WDM products that tested successfully with a wide range of HP products.
See “Certified third-party WDM and FCIP products” (page 152). Figure 26 (page 134) and
Figure 27 (page 135) show basic WDM configuration options for a typical FICON SAN fabric or
HP P9000/XP Continuous Access software replication fabric.
You can use the WDM configurations in Figure 26 (page 134) and Figure 27 (page 135) for FICON
extension and FICON SAN extension.
The configuration in Figure 26 (page 134) costs less, but does not provide long-distance link
redundancy.
