Network of optical fibers in the ring is read and write decoupled

摘要

The access node (1) is connected with active optical fibers (2,3) of respective stations (4-1 - 4-5). The data from each station is communicated between fibers based on set conditions. The fibers (3) are shared by the stations such that data packets are transmitted on channel of same wavelength. A monitoring unit (10) in each station determines the valid transmission of data packets to the fibers (3) in set wavelength range.
