Caution
In cases where there are more than six available ports, only 50% of the available ports on the switch should be populated when using the SFP+ ZR optic. Populate the ports so that there is one empty port for every two vertical ports to evenly distribute the occupied ports.
Warning
To prevent permanent damage to the ZR SFP+ and other equipment: always check the optical input power of the receiver before inserting the fiber. The maximum optical input power for the receiver is
For optical budget calculation measure cable plant losses with a 1550 nm light source and verify this to be within budget. When you calculate the maximum distance attainable using optical cable with a specified loss per kilometer (for example, 0.25 dB/km), Extreme Networks recommends that you reserve 3 dB of the total budget for losses induced by cable splices or connectors and operating margin. A minimum system budget or attenuation is required to prevent saturation of the receiver.
