As data traffic continues to surge, organizations across the globe are seeking solutions that can provide high-speed connectivity over long distances. The 100GBASE-LR4 optical module offers a reliable and efficient solution for these needs. Designed for long-range data transmission, the 100G optical module is helping businesses and data centers tackle the growing demand for bandwidth with higher efficiency and performance. In this article, we’ll explore the key features, applications, and advantages of the 100GBASE-LR4 optical module and how it plays a crucial role in modern networking.
What is the 100GBASE-LR4 Optical Module?
The 100GBASE-LR4 optical module is designed for 100 Gbps data transmission over single-mode fiber (SMF). The “LR4” designation refers to Long Range (LR) and 4-lane transmission (4x25G), which means it uses four separate lanes of data, each transmitting 25 Gbps, to achieve a total speed of 100 Gbps.
What sets the 100GBASE-LR4 apart from other 100G modules is its long-range transmission capability.
Unlike short-range modules like 100GBASE-SR4, which are designed for use within data centers and enterprise networks, the 100GBASE-LR4 is built for high-speed communication across longer distances — up to 10 kilometers over single-mode fiber. This makes it an ideal choice for applications requiring connectivity over greater spans, such as between data centers or in metropolitan area networks (MANs).
Key Features and Specifications
The 100GBASE-LR4 module is packed with advanced features designed for high-speed, long-distance communication:
Data Rate: 100 Gbps is the primary data rate supported by the 100GBASE-LR4 module. The module achieves this high-speed transmission by using four parallel lanes, each transmitting 25 Gbps.
Transmission Distance: One of the most attractive features of the 100GBASE-LR4 is its long-range capability. It can transmit data over single-mode fiber (SMF) up to 10 kilometers (km). This makes it ideal for applications that require long-distance transmission between data centers, or across wide-area networks (WANs) or metropolitan-area networks (MANs).
Wavelength: The 100GBASE-LR4 operates at a wavelength of 1310 nm, which is optimized for single-mode fiber. This wavelength provides lower attenuation and better performance over long distances.
Connector Type: The 100GBASE-LR4 module uses LC connectors, which are standard for single-mode fiber. These connectors are widely supported in networking equipment, ensuring compatibility across various platforms.
Form Factor: The module comes in a QSFP28 form factor. This compact form factor provides high-speed performance in a small, energy-efficient package, which is ideal for high-density data center environments.
Power Consumption: The 100GBASE-LR4 module is designed to be energy-efficient while maintaining high-speed transmission. Power consumption is typically in the range of 3-4W, which is relatively low compared to other high-speed modules like 100GBASE-ER4.
Applications of 100GBASE-LR4 Optical Modules
Due to its long-range capabilities, the 100GBASE-LR4 optical module is ideal for several high-demand networking applications:
Data Center Interconnects (DCI): Data centers are often geographically dispersed, and the 100GBASE-LR4 module is an excellent solution for connecting them. It allows for high-speed, long-distance data transfer between data centers, supporting large-scale cloud deployments, disaster recovery sites, and content distribution networks (CDNs).
Metropolitan Area Networks (MANs): The 100GBASE-LR4 is frequently used in MANs to provide high-speed links between different facilities within a city or metro region. With a range of up to 10 kilometers, the module enables cost-effective and reliable connections between business offices, telecom providers, and cloud service providers.
Wide Area Networks (WANs): For enterprises and service providers, the 100GBASE-LR4 enables high-speed backbone connections over WANs. It provides the necessary bandwidth to support high-volume data transfer across vast geographical distances, such as between regions or countries.
5G Networks: As 5G infrastructure continues to roll out, the 100GBASE-LR4 is being used to support the backbone of high-speed mobile networks. Its long-range capabilities and high bandwidth are essential for the increasing demands of 5G traffic and high-speed data transmission between network nodes.
Telecommunications: Telecom companies use the 100GBASE-LR4 module in their core network infrastructure to handle the growing demand for bandwidth. It provides the necessary capacity for supporting services like video conferencing, VoIP, cloud applications, and Internet of Things (IoT) traffic.
Advantages of 100GBASE-LR4 Optical Modules
The 100GBASE-LR4 optical module offers several advantages that make it ideal for long-distance, high-speed data transmission:
