A Single Port OLT (Optical Line Terminal) is a compact GPON/EPON solution designed to deliver high-speed fiber connectivity from a single PON interface. It is widely used by ISPs and network operators for small-scale FTTH deployments, pilot projects, and low-density service areas where cost-efficiency and simplicity are key.

What is a Single Port OLT?

• A network device that sits at the service provider’s central office

• Uses one PON port to distribute fiber connectivity to multiple ONUs/ONTs

• Acts as the control and aggregation point between the core network and end users

Key Features of Single Port OLT

• Single PON Interface: Supports GPON or EPON standards

• High Split Ratio: Typically supports 1:16, 1:32, or 1:64 ONU connections

• Compact Design: Small form factor, ideal for limited rack space

• Low Power Consumption: Suitable for remote or outdoor cabinets

• Easy Management: Web GUI, CLI, SNMP, and TR-069 support (model dependent)

• QoS & VLAN Support: Ensures traffic prioritization and secure segmentation

Typical Use Cases

• Small ISPs starting FTTH services

• Rural or semi-urban broadband deployments

• Business parks or apartment complexes

• Trial networks and pilot FTTH projects

• Network expansion in low-subscriber-density areas

Benefits of Using a Single Port OLT

• Cost-Effective: Lower CAPEX compared to multi-port OLTs

• Scalable: Easy upgrade path as subscriber base grows

• Quick Deployment: Faster installation and configuration

• Operational Simplicity: Minimal maintenance and monitoring effort

• Reliable Performance: Consistent bandwidth delivery for data, voice, and video

Why Choose a Single Port OLT?

A Single Port OLT is an ideal choice when you need:

• A reliable FTTH solution without heavy investment

• Flexibility to expand gradually

• Efficient fiber utilization with stable performance

It bridges the gap between affordability and carrier-grade performance, making it a practical solution for modern broadband access networks.
