The Difference Between FTTO and FTTR

Ⅰ.Target Customers

FTTO: Primarily targeted at commercial buildings and offices, it provides business users with stable, high-speed internet connections, meeting enterprise requirements for low latency, multiple connections, wireless roaming, and internal and external network isolation.

 

FTTR: Targeted more towards hotels, apartments, and homes, it provides independent internet connections for each room, addressing pain points such as slow home internet speeds, lack of roaming, poor coverage, and weak management.

 

Ⅱ.Implementation Methods

 

FTTO: This is achieved by delivering optical fiber to each room or floor, providing a fiber-to-the-room or fiber-to-the-floor solution. It typically uses optical fiber composite cables and supports return power.

 

FTTR: Fiber is laid to remote nodes, providing independent network connections for each room, typically using standard optical fiber.

 

Ⅲ.Application Scenarios

 

FTTO: Primarily used in commercial settings, such as small and medium-sized enterprise offices, distributed office spaces, educational institutions, healthcare, hotels, and the service industry, it ensures comprehensive network coverage and avoids the signal instability associated with traditional Wi-Fi.

 

FTTR: Commonly used in hotels, apartments, and homes, it provides users with an independent network environment, enabling all-optical home networking and delivering true gigabit speeds.

 

Ⅳ.Optical Modem

 

FTTO: Optical modems are typically housed in metal, which facilitates heat dissipation. They are typically placed in a computer room and typically use XGS-PON for external network access. They offer equal uplink and downlink speeds, supporting more landline access to meet enterprise applications. They can connect a large number of devices, typically up to 300.

FTTR: Optical modems are housed in plastic and typically housed in a low-voltage multimedia enclosure. They typically use XG-PON, offering higher downlink speeds but relatively lower uplink speeds. The maximum number of devices they can connect is relatively small, theoretically around 80.

Ⅴ.Using Connecting Fiber

 

FTTO: Utilizes composite optical fiber, which allows for return power.

FTTR: Utilizes standard optical fiber.
