Abstract: An optic fiber detection method of a distributed antenna system includes: at a near-end device, sending a test mode switch command to a plurality of relay devices to command the plurality of relay devices to switch to a test mode; and under the test mode: sending a first optical switch control command, the first optical switch control command being used to instruct the plurality of relay devices that have received the first optical switch control command to switch to a group of first optical channels; acquiring optic fiber connection information between the near-end device and the relay devices under all first optical channels of the group of first optical channels; and determining optic fiber connection status of the distributed antenna system according to the optic fiber connection information between the near-end device and the relay devices under all first optical channels and a working mode of the distributed antenna system.

Abstract: A method for monitoring a distributed antenna system includes: at a relay device, receiving a first operation monitoring signal sent by the near-end device, where the first operation monitoring signal carries an operation monitoring message, and the operation monitoring message includes a device address of a monitoring target device; determining whether to analyze the first operation monitoring signal according to a connection status with the near-end device; in response to a determination to analyze the first operation monitoring message signal, analyzing the first operation monitoring signal to confirm the monitoring target device and to determine whether to respond to the operation monitoring message; and in response to a determination to respond to the operation monitoring message, responding to the operation monitoring message according to the monitoring target device as confirmed.

Abstract: A method includes acquiring a plurality of sample level values of a received current frame signal; determining a current power of the current frame signal based on the plurality of sample level values; determining a current traffic signal ratio of the current frame signal based on the plurality of sample level values; taking the current power as a current pilot power of the current frame signal if it is determined that the current traffic signal ratio is less than or equal to a predetermined ratio; and determining the current pilot power of the current frame signal based on the current power, the current power floating upper limit and the current power floating lower limit if it is determined that the current traffic signal ratio is greater than the predetermined ratio. Thus, the pilot power can be accurately determined for different traffic signal ratios.
