What is 100GBASE-LR4 Optical Module?

100G is the new standard for data transmission. The 100GBASE-LR4 optical module provides 100G of bandwidth over 10 km.

100G is the future of data transmission, with a bandwidth up to 100G higher than what we have today. It is predicted that by 2020, there will be a total of 1 trillion devices connected to the internet, which will continue to grow exponentially shortly. This means that higher bandwidths are needed to handle all these connections.

The 100GBASE-LR4 optical module provides 100G of bandwidth over 10 km. It can be used in different applications such as data centres, campuses and metropolitan areas where higher speeds are required.

The 100GBASE-LR4 optical module is the latest in a line of 100Gbps modules designed to meet the increasing bandwidth needs of data centres, enterprise networks and high-performance computing.

How Does 100GBASE-LR4 Optical Module Work?

The 100GBASE-LR4 optical module is a low-cost, low-power, and low-latency optical module that operates on the 100 Gbit/s single-mode fibre. The 100GBASE-LR4 optical module provides a cost-effective way to implement a high bandwidth network. It is designed for data centre applications such as high-performance computing or storage area networks.

The 100GBASE-LR4 optical module is an all-digital device that converts electrical signals into light pulses and transmits them over an optical fibre. It uses the DSP to generate the digital waveform with the help of the electrical interface. The DSP also generates timing signals for line coding, scrambling and descrambling, and clock recovery from incoming packets.

100GBASE-LR4 is the fourth generation of 100 Gigabit Ethernet optical modules. It can be used in different data centre networks, such as data centre interconnect, server connectivity and storage area network (SAN) connectivity.

It supports 100 Gigabit Ethernet transmission on single mode fibre at distances up to 10 kilometres.

Why the Industry Needs Faster Fiber Connectivity

The fibre industry has been slow to adopt faster speeds. It's not that fibre optic networks are not available; it's just that they are not being used. This is because the industry is stuck in the gigabit era. Gigabit speeds have been around since 2001 and are still the standard for most networks today.

The need for faster internet connectivity is not just a need for people in rural areas. It is also necessary to be connected with the world at all times, even when we're not at home. As the number of devices per household increases, so does our reliance on fast and reliable internet connections - fibre speeds are necessary to meet this demand.

As more people rely on their smartphones and tablets instead of desktop computers, sharing files or working remotely becomes increasingly tricky without access to high-speed internet connections such as fibre optic networks or gigabit+.


The future of 100GBASE-LR4 Optical Modules is bright and exciting. The module has applications in many industries, and its popularity is increasing. Shortly, we may see even more applications with 100GBASE-LR4 modules. If you want to know more about the 100GBASE-LR4 optical module, please contact QSFPTEK via [email protected].
