A communication media comprising: one or more communication paths, extending from a first end to a second end; and a first connector assembly terminating the first end of the one or more communication paths, the first connector assembly including a first physical layer management interface that is isolated from signals on the one or more communication paths, the first connector assembly including: a first signal sensor configured to sense signal power propagating through the first connector assembly to/from the one or more communication paths; a first programmable processor coupled to the first signal sensor and to the first PLM interface; and one or more first data storage devices, the one or more first data storage devices including first instructions which, when executed by the first programmable processor, cause the first programmable processor to receive a first signal from the first signal sensor corresponding to the signal power detected by the first signal sensor, to send a first indication of the first signal power propagating through the first connector assembly over the first PLM interface to a first network entity, the first instructions characterised by causing the first programmable processor, when executed by said first programmable processor, to monitor the power level of the first signal in the first connector assembly, and to send an alert to the first network entity in response to the power level dropping below a threshold level. one or more communication paths, extending from a first end to a second end; and a first connector assembly terminating the first end of the one or more communication paths, the first connector assembly including a first physical layer management interface that is isolated from signals on the one or more communication paths, the first connector assembly including: a first signal sensor configured to sense signal power propagating through the first connector assembly to/from the one or more communication paths; a first programmable processor coupled to the first signal sensor and to the first PLM interface; and one or more first data storage devices, the one or more first data storage devices including first instructions which, when executed by the first programmable processor, cause the first programmable processor to receive a first signal from the first signal sensor corresponding to the signal power detected by the first signal sensor, to send a first indication of the first signal power propagating through the first connector assembly over the first PLM interface to a first network entity, the first instructions characterised by causing the first programmable processor, when executed by said first programmable processor, to monitor the power level of the first signal in the first connector assembly, and to send an alert to the first network entity in response to the power level dropping below a threshold level. a first signal sensor configured to sense signal power propagating through the first connector assembly to/from the one or more communication paths; a first programmable processor coupled to the first signal sensor and to the first PLM interface; and one or more first data storage devices, the one or more first data storage devices including first instructions which, when executed by the first programmable processor, cause the first programmable processor to receive a first signal from the first signal sensor corresponding to the signal power detected by the first signal sensor, to send a first indication of the first signal power propagating through the first connector assembly over the first PLM interface to a first network entity, the first instructions characterised by causing the first programmable processor, when executed by said first programmable processor, to monitor the power level of the first signal in the first connector assembly, and to send an alert to the first network entity in response to the power level dropping below a threshold level.
