OLT vs ONT Management in GPON Networks

OLT and ONT management are two critical components of GPON network operations. Understanding their differences is essential for efficient ISP management.

What Is OLT Management?

OLT management focuses on controlling the core GPON infrastructure. This includes ports, VLANs, profiles, uplinks and overall capacity.

What Is ONT Management?

ONT management handles subscriber equipment, including activation, authentication, signal levels and service profiles.

Key Differences

• OLT = central network control
• ONT = customer edge management
• OLT affects many users
• ONT affects individual subscribers
