QUESTION 187
Regarding EPON, which of the following descriptions is incorrect?

The EPON standard is one of many TDM-PON standards and has the basic characteristics of a TDM-PON network: a tree topology network is composed of OLT, ONU and ODN (Optical Distribution Network).

In the logical topology, the EPON protocol establishes a logical link for the OLT to each ONU, and the leading byte of the Ethernet data frame carries the logical link identity, that is, LLID (Logical Link Identity).

The downstream data stream from the OLT to the ONU is encapsulated as an Ethernet message, and the corresponding LLID is attached and sent in the tree PON network. The optical splitter in the ODN broadcasts the data stream to each branch, and all ONUs can receive the downlink Ethernet data frame, and selectively receive their own data according to the LLID.

In the upstream direction from the ONU to the OLT, each ONU uses the broadcast mode to share the upstream bandwidth.

QUESTION 188
Which of the following statements about XGS-PON data transmission are incorrect? (Select All that Apply)

Each service/user must use different GEM port channels.

GEM ports in a T-CONT cannot exceed twice the number of users.

All services can be carried by the same T-CONT.

Data in the same GEM port can be received by only one ONU.

TRUE

FALSE

QUESTION 192
A trunk interface allows packets from VLAN 100, VLAN 200, and VLAN 300 to pass through.
However, only packets from VLAN 100 and VLAN 200 carry tags, and packets from VLAN 300 do not carry tags. Which of the following is the possible cause?

The PVID of this port is 300.

The port trunk allow-pass vlan 100 200 command is set during trunk port configuration, but VLAN
300 is not included.

The PVIDs of this port are 100 and 200.

GVRP is enabled on this interface.

QUESTION 193
In the downstream direction of the GPON, all ONUs receive the same data because the broadcast mode is adopted. In the upstream direction, because the same optical splitter is used, the data of a branch fiber can also be received by another branch fiber.

TRUE

FALSE

QUESTION 194
Among common ODN products, large square heads, round heads, and small square heads refer to:

SC, FC, LC

FC, LC, SC

LC, SC, FC

None of the above

* SC (Large Square Head): Square connector with a push-pull design.
* FC (Round Head): Round connector with a screw-on mechanism.

QUESTION 195
The OLT supports multiple protection switching modes for GPON lines. The ( ) technology is supported by the OLT to protect the backbone and branch optical fibers at the same time.

Type C

Type D

Type A

Type B

GPON networks use various protection mechanisms to ensure high availability and reliability. These mechanisms are classified into different types based on their scope and functionality:
* Type A :
* Protects only the trunk fiber (between the OLT and the splitter).
* Does not protect branch fibers (between the splitter and ONUs).
* Type B :
* Protects the trunk fiber but does not provide simultaneous protection for branch fibers.
* Type C :
* Provides full protection for both the trunk and branch fibers.
* Uses redundant fibers and splitters to ensure continuity in case of a failure.
* Type D :
* Not a standard GPON protection type.
Since the question specifies protection for both the backbone (trunk) and branch fibers, the correct answer is Type C .

QUESTION 196
The monitoring of environmental quantities refers to the monitoring of some environmental factors that may cause equipment damage, malfunctions, etc. Which of the following is not the subject of environmental monitoring?

Temperature

Humidity

Flooding

Board status

QUESTION 197
Is the following description correct? The simplified method of MA5600T/MA5680T GPON Internet service is optimized for the excessive number of templates and complicated configuration in the template mode, reducing user configuration workload and subsequent maintenance costs. The simplified mode currently only supports GPON FTTH scenarios. For newly-built GPON FTTH scenarios and scenarios that do not require high QoS, the simplified mode can be used for service configuration.

True

False

QUESTION 198
Which of the following statements about the test of the mean optical transmit power of an optical interface is incorrect?

Repeat the preceding steps to check whether the maximum and minimum values of the mean optical transmit power meet the technical requirements.

The optical power meter is calibrated.

The fiber connector and the optical connector on the panel of the optical interface board are clean and connected properly.

Connect one end of the test pigtail to the Rx port on the optical interface board, and connect the other end of the pigtail to the optical power meter.

* Mean Optical Transmit Power Testing :
* Testing the mean optical transmit power involves measuring the output power of an optical interface using an optical power meter.
* Analysis of Options :
* Option A : Correct. Repeating measurements ensures accuracy and verifies compliance with technical specifications.
* Option B : Correct. Calibration of the optical power meter is essential for accurate measurements.
* Option C : Correct. Clean and proper connections prevent signal loss and ensure reliable measurements.
* Option D : Incorrect. The test pigtail should be connected to the Tx (transmit) port of the optical interface board, not the Rx (receive) port.
* Why D?
* Connecting the test pigtail to the Rx port instead of the Tx port is incorrect and would result in no measurable transmit power.
Thus, the correct answer is D .

QUESTION 199
What are the maximum splitting ratios supported by MA5680T H801GPBC and H802GPBD?

1: 32, 1: 64

1: 64, 1: 64

QUESTION 200
The customer needs to access the following information points: AP, PC, POTS, and CATV.
Which of the following statements about data transmission of these information points by ONUs is correct?

All types of data are encapsulated into Ethernet frames before PON-related encapsulation and transmission over one fiber.

When an OLT is connected downstream to an ONU, one fiber and two wavelengths are used to carry CATV and other services respectively. All services except CATV are encapsulated into Ethernet frames before PON encapsulation.

POTS voice services are TDM services and directly encapsulated in GEM frames.

When an OLT is connected downstream to an ONU, one fiber and two wavelengths are used to carry CATV and other services respectively. For all services except CATV, if POTS is a TDM service, it is transparently transmitted.

Service Types and Transmission:
AP/PC (Data Services): These services are typically Ethernet-based and encapsulated into Ethernet frames before being transmitted over the PON network.
POTS (Voice Services): Voice services can be either TDM-based or packetized. In modern GPON/XGS- PON systems, POTS is often packetized into Ethernet frames.
CATV (Video Services): CATV uses a separate wavelength (1550 nm) for analog or digital video transmission.
Wavelength Division Multiplexing (WDM):
GPON/XGS-PON systems use WDM to transmit multiple services over a single fiber:
One wavelength (1490 nm or 1577 nm) is used for data services (Ethernet).
Another wavelength (1550 nm) is used for CATV.
Analysis of Options:
Option A: Incorrect because CATV is not encapsulated into Ethernet frames; it uses a separate wavelength.
Option B: Correct because CATV uses a separate wavelength, and other services are encapsulated into Ethernet frames before PON transmission.
Option C: Incorrect because POTS services are typically packetized into Ethernet frames in modern systems, not directly encapsulated in GEM frames.
Option D: Incorrect because POTS is not transparently transmitted in modern GPON/XGS-PON systems.
Thus, the correct answer is B.

QUESTION 201

GE, GE (PoE), POTS

GE, GE (PoE)

GE (PoE): Powers the AP.
