Figure 17: Installed XFP Module (Summit family switch and BlackDiamond 8800 series switch)

6If you are installing only one XFP module, make sure that all unoccupied ports are covered with rubber dust covers, which are shipped with the option card or I/O module (see Installed XFP Module (Summit family switch and BlackDiamond 8800 series switch)).

Note

To prevent permanent damage to a ZR XFP or DWDM XFP, always check the optical input power of the receiver before inserting the fiber cable. The maximum optical input power for these XFPs is –7 dBm. If you use an optical loopback for diagnostics, the loopback requires a minimum of 15 dB optical attenuation. The recommended attenuation range is 15 to 20 dB.

To ensure that your XFP module is undamaged upon installation, you can correlate factory test data with your installation site test data by consulting the average power reference values shown on the XFP module test data sheet (Part No. 121080-00) enclosed with the module.
