Question

How do you distinguish between Passive Optical Network (PON) and Gigabit Passive Optical Network (GPON)?

1. PON is a network architecture that brings fiber cabling and signals to the home using a point-to-multipoint scheme that enables a single optical fibre to serve multiple premises.

2. PON standard differs from non-PON standards in that it achieves higher bandwidth and higher efficiency using larger, variablelength packets.

3. GPON offers efficient packaging of user traffic, with frame segmentation allowing higher Quality Of Service (QOS) for delaysensitive voice and video communications traffic.

Which of the statements given above are correct?

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Answer 1

The correct option is: (c) 1 and 3 only

Explanation:

GPON standard differs from other passive optical network standards in that it achieves higher bandwidth and higher efficiency using larger variable length packets. GPON offers efficient packaging of user traffic with frame segmentation allowing higher quality of service for delay sensitive voice and video communications traffic. On the other hand, PON is a network architecture that brings fibre cabling and signals to the home using a point-to-multipoint scheme that enables a single optical fibre to serve multiple premises.
