Question 44/102
The scope of protection of the (multiple choice) GPON Type B dual attribution protection includes
Correct Answer: B,C
In GPON protection schemes, Type B (dual-homing to the same OLT) provides redundancy by using two PON ports on the same OLT (working/standby) and a redundant feeder path via a 2×N splitter or equivalent ODN design. Thus, the protection covers the OLT PON interfaces and the feeder fiber segment. It does not provide protection for the branch (distribution) fibers from the splitter to the ONUs, and it does not involve dual OLTs-that is the scope of Type C.
