The invention provides an optical fiber transceiver, a pulse signal transceiving system and a pulse signal transceiving method. The optical fiber transceiver comprises an optical transmitter and an optical receiver; the optical transmitter is connected with transmitting terminal equipment; the optical transmitter is connected with the optical receiver through an optical fiber line; the optical transmitter is used for performing dark pulse modulation on the pulse time-frequency electric signal sent by the sending terminal equipment, and performing electro-optical conversion on the modulated pulse time-frequency electric signal to obtain a pulse time-frequency optical signal; the optical receiver is connected with the receiving terminal equipment; and the optical receiver performs photoelectric conversion on the pulse time-frequency optical signal transmitted by the optical fiber line to obtain a transmitted pulse time-frequency electric signal, and transmits the transmitted pulse time-frequency electric signal to receiving terminal equipment. The optical transmitter provided by the invention performs dark pulse modulation on the time-frequency electric signal sent by the sending terminal equipment, and has the advantages of optical fiber line attenuation change resistance, stable transmission delay and low cost.
Description
technical field [0001] The invention relates to the technical field of optical fiber transmission, in particular to an optical fiber transceiver, a pulse signal transceiving system and method. Background technique [0002] In many large-scale measurement networks, pulse time-frequency devices are required for time synchronization, and a central device sends time synchronization pulses or measurement start pulses to other terminal devices, typically transmitting pulse-per-second signals (PPS). This type of transmitted signal is characterized by an extremely low duty cycle. In some cases, a pulse signal with a width of tens of ns is sent within a time interval of one second, and the duty cycle can be as low as 10E-7. When optical fiber is used as the transmission medium of pulsed time-frequency signals, the length of the optical fiber ranges from several meters to tens of kilometers. Due to the influence of various environmental factors, the transmission delay of the signal ch...
