문제3
The decrease of optical power when light passes through a passive optical component is called the____.
(Enter only letters.)
The decrease of optical power when light passes through a passive optical component is called the____.
(Enter only letters.)
정답:
insertion loss
Explanation:
Insertion loss refers to the decrease of optical power that occurs when light passes through a passive optical component such as connectors, splitters, filters, or splices. This loss results from absorption, scattering, or imperfect coupling within the component. In optical transmission systems, insertion loss is a critical parameter affecting link budget and overall signal quality. HCIP-Transmission materials stress managing insertion loss to ensure sufficient power reaches the receiver and to maintain the integrity of transmitted signals over long distances. Proper component selection and maintenance help minimize insertion loss in WDM systems.

문제6
In a scenario where non-convergence OTU boards process standard SDH signals, both site A and site B are WDM sites, and the R_LOS alarm is detected on the client side of the OTU board at site A. After an alarm is processed on the WDM side of the OTU board, the REM_5F alarm is reported on the client side of the downstream site B. Then, site B transmits the signals to its downstream client device and reports the R^LOS alarm to the client device.
