100Mbps Single-Mode Fiber Repeater

A 100Mbps Single-Mode Fiber Repeater extends and regenerates Ethernet signals over long distances using single-mode fiber, ensuring reliable 100Mbps data transmission.

Overview

A 100Mbps single-mode fiber repeater is a device designed to extend Ethernet signals over long distances using single-mode fiber optic cables. These repeaters regenerate the signal to maintain data integrity, typically using 3R (Re-amplify, Reshape, Retime) technology, which ensures that the signal remains strong and error-free across extended fiber links . They are commonly used in industrial networks, campus networks, and long-haul fiber connections.

Key Features

• Data Rate Support: Specifically designed for 100Mbps Ethernet (100Base-FX) networks .
• Distance Extension: Can transmit signals over distances up to 100 km (62 miles) depending on the transceiver and fiber quality .
• Protocol Independence: Many fiber repeaters, such as the Lantronix S3100-4040, support multiple protocols and can interconnect different fiber types or perform wavelength conversion in CWDM applications .
• SFP Compatibility: Devices often use Small Form-Factor Pluggable (SFP) transceivers, allowing flexible deployment and easy replacement or upgrades .
• Single-Mode Fiber: Uses 1310 nm wavelength for long-distance transmission with LC connectors, ideal for point-to-point links .

Types of Fiber Repeaters

1. SFP-to-SFP Fiber Mode Repeaters: Connect two fiber links back-to-back, protocol-independent, suitable for multiple applications including Ethernet, Fibre Channel, ATM, and video .
2. Ethernet Fiber Repeaters: Designed specifically for Ethernet networks, regenerating the signal to maintain 100Mbps data integrity over long distances .

Applications

• Extending 100Mbps Ethernet networks beyond standard fiber limits.
• Connecting single-mode to multimode fiber or performing wavelength conversion in CWDM/DWDM networks .
• Industrial automation, campus networks, and metropolitan area networks requiring long-distance fiber links.

Example Products

• Lantronix S3100-4040: Stand-alone fiber-to-fiber media converter supporting 100Mbps to 2.5Gbps, protocol-independent, with two open SFP slots for single-mode or multimode fiber conversion .
• 100Mb SFP Transceivers: Single-mode 1310 nm SFP modules capable of transmitting up to 100 km, ideal for extending 100Mbps Ethernet links . Using a 100Mbps single-mode fiber repeater ensures reliable long-distance Ethernet connectivity, signal integrity, and flexibility in network design, making it a critical component for extended fiber optic networks.
