100GBASE FR Optical Transceiver Overview

As technology advances, modern communication networks face unprecedented challenges. The 100GBASE-FR, based on the IEEE 802.3 Ethernet standard, offers high-speed optical fiber transmission at 100 gigabits per second over a 2-kilometer range of single-mode fiber. This solution meets the current high-speed data transmission needs of data centers, cloud providers, and large institutions, laying a strong foundation for future network expansion.

What Is 100G FR?

100GBASE-FR is a designation for a type of Ethernet transmission over optical fiber. It represents part of the IEEE 802.3 Ethernet standards. In this case, the "100GBASE" denotes an Ethernet connection at a speed of 100 gigabits per second (Gbps), while "FR" indicates that the specification is for a single-mode fiber with a reach of up to 2 km.

The physical layer transceiver for 100GBASE-FR in the Ethernet equipment is specified to ensure interoperability and to define the modulation techniques, optical wavelengths, and other necessary parameters to achieve communication over the designated distances. It usually employs wavelength division multiplexing (WDM) where different data streams are transmitted simultaneously over the same fiber but on different wavelengths to maximize the use of the fiber infrastructure.

How Does 100G QSFP28 FR Work?

It uses four 25Gbps channels to achieve a transmission rate of 100Gbps. Specifically, 100G FR uses four parallel 25Gbps optical channels, with each channel corresponding to a different fiber core. These channels can transmit data through fiber and then be reassembled into a continuous 100Gbps data stream at the receiving end. This parallel transmission method effectively increases the transmission rate while maintaining a shorter transmission distance.

In practical applications, 100G FR typically uses optical modules for transmission, which can be inserted into the ports of network devices to achieve high-speed data transmission and reception. This method is very common for intra-data center or short-distance metropolitan area network connections, providing an effective solution for high-density data transmission.

Advantages of 100G FR

The benefits of using 100G FR modules, which stand for 100 Gigabit Ethernet Fixed Rate, a high-speed network transmission technology typically utilized in data centers, large institutions, and by cloud service providers, include:

• High Bandwidth: 100G FR offers data transfer rates of up to 100 gigabits per second, essential for handling large datasets, high-definition video streaming, and complex cloud computing tasks.

• Increased Efficiency: High transfer rates mean that large amounts of data can be processed with fewer connections and devices, reducing network complexity and management overhead.

• Reduced Latency: The 100G FR technology can decrease data transfer latency, which is crucial for latency-sensitive applications such as financial transactions and online gaming.

• Energy Savings: 文字

• Compatibility and Standardization: 100G FR follows industry standards, ensuring compatibility with equipment and networks from different manufacturers.

• Fault Tolerance and Reliability: 100G networks typically offer better redundancy and recovery mechanisms, providing more reliable services and reducing downtime due to network failures.

100GBASE FR Application

100G FR (Fixed Rate), or 100G Single Lambda, is usually used in data centers, enterprise core networks and service provider environments. The following are some specific application scenarios:

Data Center Interconnection

High-speed connections are required between or within data centers to synchronize, back up and manage large amounts of data. 100G FR optical modules are suitable for connections between these data centers and between racks, ensuring high-speed data transmission.

High-Performance Computing (HPC)

In fields such as scientific research, engineering simulation, and financial modeling, HPC environments require high-bandwidth connections to handle large-scale parallel computing tasks, and 100G FR can meet this demand.
