Method and apparatus for providing gain shape compensation |
摘要 |
To monitor and compensate for gain shape variations in an optical fiber communication system usually a submarine such system, a low-frequency amplitude modulation is imposed at known amplitude upon location, usually a shore terminal (2). At another location, e.g. equalisation station (10), the received amplitude is monitored. Variations as between different channels represent response variations also in relation to signals and are compensated for.
