| 摘要 |
The present invention relates to a signal processing method capable of increasing a channel capacity by allocating two or more wavelength channels per coarse wavelength division multiplexing (CWDM) wavelength grid and a bidirectional CWDM ring network system for the same. The bidirectional CWDM ring network system, according to the present invention, forms an optical signal having a specific wavelength, allocates two or more wavelength channels per CWDM wavelength grid and inserts or extracts the optical signal having the specific wavelength into or from optical signals formed by two or more optical transceivers. |
