NO.226 H4 is used to indicate the () and () of the payload.

NO.227 TNG 1N401 board supports mixed transmission of multiple ODUk particles.

NO.228 Which of the following is the basic requirement of DWDM system on the light source?

NO.229 Automatic Laser Shutdown (ALS): When no optical signal is received, the ALS function automatically turns off the corresponding optical module. This feature protects field maintenance personnel.

NO.230 OSN1500/2500/3500/7500 supports DC and AC power inputs.

NO.231 Which of the following is the steps to multiplex a low-speed service into a high-speed SDH service? (Multiple choice).

NO.232 The value of the MFAS byte increases with the sequence number of the OTUk/ODUK base frame and includes the most () base frames.

NO.233 Which subtype of tributary SNCP protection requires no electrical relay station in the subnet along which the ODUk signal passes?

NO.234 The two PIU/APIU boards of the OptiXtrans E6616 or E6608 (0ptiX OSN 1800 V Pro or 1800 1 Pro) equipment use hot backup to power the system. When one PIU/APIU board fails, the system can still work normally.

NO.235 The technology of using a local oscillator laser of the same frequency to coherently receive the optical signal and recover the amplitude, phase and polarization state information from the received signal is called coherent reception technology.

NO.236 IEEE802.3 standard is developed for which of the following technologies?

NO.237 The current sparse wavelength division multiplexing system generally operates in the band from
1271nm to 1611nm. Which of the following is the channel spacing?
