The apparatus accesses a conflict register, acquires an occupancy status of the N paths according to a value of the conflict register, then performs a concurrent probe on M optical module cages connected to M paths that are in the N paths and whose occupancy status are not occupied by system software, to obtain a probe result, where the probe result includes availability information of optical modules of the M optical module cages and a type of the optical modules, and finally, writes the probe result into an availability register, so that the system software can acquire the probe result from the availability register. Therefore, whether an optical module is available in an optical module cage can be monitored in real time and fast insertion and removal operations on the optical module can be sensed. | 2016-06-30 |
20160191154 | IN-SERVICE MONITORING OF A FIBEROPTIC NETWORK - An optical fiber breakage point may be located by coupling to the optical fiber an out-of-band optical test signal modulated at a periodic modulation pattern. A distance to the breakage point may be determined from a difference between modulation patterns of transmitted and received test signals. | 2016-06-30 |
20160191155 | INFORMATION COMMUNICATION METHOD - An information communication method of transmitting a signal using a change in luminance is provided. The information communication method includes: determining a pattern of the change in luminance, by modulating the signal to be transmitted; and transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance.
