問題4
FILL BLANK
Colored refers to ____, indicating that each add/drop port can only add or drop fixed wavelengths. (Enter only lowercase letters.)
FILL BLANK
Colored refers to ____, indicating that each add/drop port can only add or drop fixed wavelengths. (Enter only lowercase letters.)
正確答案:
fixed wavelength
Explanation:
In ROADM terminology, a "colored" port is tied to a specific wavelength and cannot be tuned, so "colored" refers to fixed wavelength.

問題5
Signal flow analysis is used to divide an entire network into several OMSs, identify the faulty section, determine whether the fault is occurring unidirectionally or bidirectionally, and then locate the fault along the signal flow direction based on fault information.

問題7
The OA module inside an EMR8 board provides the____function. With this function, when one or more channels are added or dropped or optical signals of some channels fluctuate, the signal gain of other channels is not affected, (Enter only lowercase letters.)
The OA module inside an EMR8 board provides the____function. With this function, when one or more channels are added or dropped or optical signals of some channels fluctuate, the signal gain of other channels is not affected, (Enter only lowercase letters.)
正確答案:
Gain locking
Explanation:
The Optical Amplifier (OA) module inside an EMR8 board includes a critical function called "gain locking." This function ensures that when channels are added, dropped, or experience fluctuations, the gain of the remaining channels stays stable. Without gain locking, changes in one channel's power could inadvertently affect the amplification of other channels, causing signal degradation and uneven performance. Gain locking maintains consistent output power levels and improves overall system stability, which is vital in dense WDM networks. This function helps avoid cascading issues during dynamic network changes and supports reliable service delivery in HCIP-Transmission systems.
