Installing the shelf, OADM, and OMUX

The shelf and multiplexers are passive equipment and require no power or electronic This chapter describes how to install optical routing components, and includes the following topics.

•“Preparing for installation” next

•“Installing the shelf” on page 37

•“Inserting a CWDM OADM or a CWDM OMUX” on page 38

•“Removing a CWDM OADM or a CWDM OMUX” on page 44

•“Cabling a CWDM OADM or a CWDM OMUX” on page 39

Preparing for installation

Before installing the optical routing system, observe the following:

•“Exceeding class 1 power level warning” next

•“Environmental and physical requirements” on page 36

•“Electrostatic discharge” on page 36

•“Handling and cleaning fiber optic equipment” on page 49

Exceeding class 1 power level warning

Muxing together several CWDM GBICs can produce a radiant power level in the fiber which exceeds the class 1 laser Limit. The warning in Figure 14 appears on the CWDM OMUX.
