FIELD: optical communication equipment. SUBSTANCE: method involves establishing connection between stations using header, which is stable to physical noise and can be recognized by all participating stations. Said header at least has preamble, which consists of frames which provide periodic pulse sequence, number of slots for frame and frame content, which is known to participating stations. Preamble is used for relative synchronization and carrier detection by receiving stations. In addition, header has unique synchronization word, which is used for absolute synchronization of receiving stations. Said synchronization word follows control field, which has fixed length and known structure. Said control field provides possibility for receiving stations to get information about modulation method used for data transmission. In some circumstances, it is useful to get another control information in control field in order to keep communication channel and network control protocol. In addition, it is possible to exchange information in order to negotiate or adapt data transmission rate used for data transmission. EFFECT: increased throughput depending on conditions of data transmission in channel. 38 cl, 14 dwg
