Optical module power of the switch
Generally, for a standard 10G-SR (Short Range) module, the RX power should be between -2 dBm and -9 dBm. Always ensure the level is higher than the “Receiver Sensitivity” limit found in the Cisco datasheet. The TX (transmit) and RX (receive) power levels significantly affect everything from signal strength to transmission distances and the overall optical power. Use an Optical Attenuator. This is a passive device that reduces signal strength. For a ZR module used over short distances, a 10dB or 15dB attenuator is usually required to prevent permanent hardware damage. The Problem: Your switch is not sending enough light. Cause: The laser diode inside the.
