GPON is an Ethernet-based passive optical access technology that complies with IEEE 802.3ah.
- A. FALSE
- B. TRUE
Answer: A
Explanation:
* GPON Overview :
* GPON (Gigabit Passive Optical Network) is a fiber-optic access technology standardized by the ITU-T (International Telecommunication Union) under the G.984.x series of standards.
* It is not based on Ethernet but uses its own framing structure called GEM (GPON Encapsulation Method) for data transmission.
* IEEE 802.3ah :
* IEEE 802.3ah is the standard for EPON (Ethernet Passive Optical Network) , which is a competing technology to GPON.
* EPON uses Ethernet frames for data transmission and is standardized by the IEEE, unlike GPON, which is standardized by ITU-T.
* Why FALSE?
* The statement incorrectly associates GPON with IEEE 802.3ah, which applies to EPON, not GPON.
Thus, the correct answer is B .

- B. Each GPON port supports up to 32 ONU/ONT
- C. Each GEM Port is identified by a unique Port-ID. The Port-ID ranges from 0 to 4095 and is globally assigned by the OLT. That is, each ONU/ONT under the OLT cannot use GEMs with repeated Port-IDs. Port.
- D. Each T-CONT is composed of one or more GEM Ports, and each GEM Port carries a service flow. A T-CONT can carry data streams of one or more types of services.
Answer: B

Generally, which of the following is not a split ratio of an optical splitter in a PON?
- A. 1:4
- B. 1:8
- C. 1:18
- D. 1:14
Answer: C,D
Explanation:
* Optical Splitter Overview :
* Optical splitters are passive devices used in PON (Passive Optical Network) systems to divide the optical signal from the OLT into multiple paths for ONUs.
* Standard Split Ratios :
* Common split ratios include:
* 1:4 : Divides the signal into 4 paths.
* 1:8 : Divides the signal into 8 paths.
* 1:16 : Divides the signal into 16 paths.
* 1:32 : Divides the signal into 32 paths.
* 1:64 : Divides the signal into 64 paths.
* Non-standard split ratios like 1:14 or 1:18 are not supported because they do not align with the design principles of PON systems.
* Why B, C?
* 1:14 and 1:18 are not standard split ratios and are not used in PON systems.
Thus, the correct answers are B, C .

NEW QUESTION # 50
On an Ethernet network, ARP packets are classified into ARP Request packets and ARP Response packets. In the initial communication phase, how are ARP Request packets transmitted on the network?
- A. Anycast
- B. Multicast
- C. Unicast
- D. Broadcast
Answer: D
Explanation:
The Address Resolution Protocol (ARP) is used to map IP addresses to MAC addresses in a local network.
ARP operates at the data link layer (Layer 2) of the OSI model and is essential for communication within a LAN.
* ARP Request :
* When a device needs to communicate with another device on the same network but does not know the destination's MAC address, it sends an ARP Request .
* Since the sender does not know the MAC address of the destination, it cannot send the request directly to the destination using unicast. Instead, the ARP Request is sent as a broadcast packet to all devices on the local network.
* The broadcast packet has a destination MAC address of FF:FF:FF:FF:FF:FF, which ensures that all devices on the network receive the packet.
* ARP Response :
* The device with the matching IP address responds with an ARP Reply , which is sent as a unicast packet back to the requesting device.
* Why Not Other Options?
* Anycast : This involves sending packets to the nearest device in a group of devices sharing the same IP address. ARP does not use anycast.
* Unicast : ARP Requests cannot be sent as unicast because the sender does not yet know the destination's MAC address.
* Multicast : Multicast is used for sending packets to a specific group of devices, but ARP Requests are sent to all devices on the network, making broadcast the correct choice.
Thus, ARP Requests are transmitted as broadcast packets .

According to the ITU-T G.984.X series standards, the downstream transmission wavelength of the GPON network is ( ) nm.
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
* GPON Wavelengths :
* GPON networks use specific wavelengths for upstream and downstream transmission:
* Downstream (OLT to ONU) : 1490 nm.
* Upstream (ONU to OLT) : 1310 nm.
* Optional CATV overlay : 1550 nm (used for video services).
* Why 1490 nm?
* The ITU-T G.984.x standards specify 1490 nm as the wavelength for downstream data transmission in GPON networks. This wavelength is chosen for optimal performance in fiber- optic communication.
* Other Options :
* 850 nm : Used in multimode fiber for short-distance communication, not in GPON.
* 1310 nm : Used for upstream transmission in GPON.
* 1550 nm : Optional wavelength for CATV overlay, not for standard downstream data.
Thus, the correct answer is A .
