• One monitor port, also known as tap port, optionally used to connect optical monitoring
equipment for checking optical link quality
• One network port to allow users to connect to additional CWDM modules to extend their SAN
or network
• Dual LC-type connectors for all optical connections

The CWDM Slot A 4-port Add/Drop Multiplexer ( Figure 2 ) and CWDM Slot B 4-port Add/Drop
Multiplexer ( Figure 3 ) modules are passive optical devices and do not require power. The two modules
have the following features:
• Add/drop capability for four CWDM wavelengths
• Identical functionality with different sets of four wavelengths
• Allow wavelengths that have not been dropped to continue transmitting on the network without
interference
• Four unidirectional fiber pairs for equipment side drops
• Two monitor ports, also known as tap ports, optionally used to connect optical monitoring equipment
for checking optical link quality
• One network port and one pass port enabling users to optionally connect to additional CWDM
modules to extend the SAN or network.
• Dual LC-type connectors for all optical connections

Supported configurations using HP CWDM MUX modules
The HP CWDM MUX modules enable users to expand the capacity of point-to-point networks that
typically utilize a single pair of single mode optical fiber. This is useful in situations where there is either a
limited supply of, or access to, optical fiber. In these situations, a point-to-point optical network is typically
used to carry data between two end points without branching out to other points or nodes. Point-to-point
connections can be expanded four or eight-fold when the CWDM 8-port Multiplexer/Demultiplexer
module is deployed at each end. This type of connection is usually the best way to transport many
