Unlocking new revenue growth for telecom: 10G-PON network planning guidelines

Why 10-gigabit networks are the inevitable path for operators:

1. Gigabit networks have become the standard in 56 countries and regions, and the technological advantages are gradually diminishing.

2. Access technologies (50G PON, Wi-Fi 7/8) and transmission technologies (400G/800G) have matured.

3. There is a strategic need to transition from "connection services" to "experience services."

Cost Analysis

Initial Investment Differences: 10-Gigabit equipment costs approximately 1.8-2.5 times more than Gigabit equipment.

Cost per Unit Bandwidth: The cost per Mbps of a 10-Gigabit network decreases by 40-60%.

Operation and Maintenance Costs: Intelligent operation and maintenance systems reduce OPEX by 25-35%.

Lifecycle: The technical lifecycle of 10-Gigabit equipment is extended by 50%.

FTTH 10 Gigabit Network Upgrade Guide for Access Networks

Target Network Architecture: User Terminal → 10 Gigabit Optical Modem → OLT (10G-PON) → Metropolitan Area Network (100G/400G) → Backbone Network (400G+/1T)

First, Planning of key equipments for access networks

1. Use a Combo PON board (one optical module supports both GPON and 10G-PON).

2. Re-plan the optical link power budget; this may require adjusting the splitter or reducing the number of users covered per PON port.

3. ONT/ONU terminals need to support 10G Ethernet electrical (or optical) ports and robust Wi-Fi 7 (future) access capabilities to ensure the internal network does not become a bottleneck.

4. 10 Gigabit connections are more sensitive to fiber optic loss. Ensure the fiber optic link is clean and the connectors are of high quality.

Second, Metropolitan Area Network and Aggregation Layer Upgrade

Network architecture flattening: Reducing network layers and latency, evolving from the traditional "core-aggregation-access" model to "core-aggregation" or "core-access" models.

Key equipment and component planning:

Aggregation switch, Upgraded to 100G/400G uplink and 25G/50G/100G downlink
Metropolitan Area Network (MAN) transmission, Upgrade to 200G/400G/800G channels and deploy OTN down to the aggregation room or integrated service access point. Utilize higher-speed optical modules and provide channels for 10 Gigabit services through OTN hard slicing.
