H35-210_V2.5 · Question #394
Compared with GPON, XGS-PON can cover more users and provide higher bandwidth without changing the ODN network architecture.
The correct answer is A. TRUE. GPON vs. XGS-PON: GPON: Provides asymmetric bandwidth (2.5 Gbps downstream, 1.25 Gbps upstream) and supports up to 128 ONUs per PON port. XGS-PON: Provides symmetric bandwidth (10 Gbps upstream and downstream) and supports up to 256 ONUs per PON port. ODN Compatibility: XGS-PON…

Explanation
GPON vs. XGS-PON: GPON: Provides asymmetric bandwidth (2.5 Gbps downstream, 1.25 Gbps upstream) and supports up to 128 ONUs per PON port. XGS-PON: Provides symmetric bandwidth (10 Gbps upstream and downstream) and supports up to 256 ONUs per PON port. ODN Compatibility: XGS-PON operates over the same ODN (Optical Distribution Network) as GPON, meaning no changes are required to the existing fiber infrastructure. XGS-PON uses different wavelengths (1577 nm downstream, 1270 nm upstream) to coexist with GPON on the same ODN using wavelength division multiplexing (WDM). XGS-PON supports higher bandwidth and more users while maintaining compatibility with the existing GPON ODN architecture. Thus, the correct answer is A.
