XGS-PON Combo OLT FAQ
Q1: What is an XGS-PON Combo OLT?
A: An XGS-PON Combo OLT is an optical line terminal that integrates GPON and XGS-PON technologies into a single module. It allows operators to serve both GPON and XGS-PON ONUs over the same Optical Distribution Network (ODN), simplifying network upgrades.
Key features include:
GPON & XGS-PON coexistence
Symmetrical 10Gbps services
Shared ODN infrastructure
Smooth migration to 10G PON
Lower upgrade costs
It is widely used in FTTH, FTTB, and enterprise broadband networks.
Q2: How does an XGS-PON Combo OLT work?
A: An XGS-PON Combo OLT combines GPON and XGS-PON optical signals into a single interface using different operating wavelengths. This allows existing GPON users and new XGS-PON subscribers to share the same fiber and splitter network without service interruption.
The solution simplifies deployment while protecting existing network investments, enabling operators to upgrade network capacity without rebuilding the optical distribution infrastructure.
