This paper proposes a multiplexing method of sensor subnets for the multiparameter heterogeneous fiber sensor network (MHFSN). In each sensor subnet, a continuous laser signal with a different wavelength is designed. This signal is used to identify the access subnet type and to monitor the subnet at all times. The correct recognition rate of this method can reach 100%. This method broadens the access subnet type, increases the number of sensors, and widens the measurement range. At the same time, we propose a robustness analysis model for MHFSN and analyze the light source stability of MHFSN. When the access subnet number increases, the failure rate of the shared mode gradually increases from 0.01 to 0.09, while the failure rate of the dedicated mode remains unchanged. The robustness model provides an effective means for system stability analysis.
