With the rapid growth of data center network and the increase in demand for communication, it has becomes one bottleneck to achieve long-distance transmission and high bandwidth. The solution seems to now be 100G LR4 modules that are rapidly becoming the center of gravity for large data center architectures, because their long-range transmission capability is quite impressive as well. The 100G LR4 modules are used in cross-regional data center interconnection and large-scale data transmission applications, which can provide a stable and efficient transmission network build.

 

100GBASE-LR4 Introduction

 

The 100G LR4 (Long Range 4 Channel) module is an optical module designed to realize long-distance high-speed data transmission. It uses a 1310nm wavelength to transmit 25 Gbps of data over each of four parallel channels for 100 Gbps. Typically used in Single Mode Fiber (SMF) environments, the module has a transmission distance of up to 10km, making it ideal for connecting Wide Area Networks (WANs), Metropolitan Area Networks (MANs), and large-scale data centers.

 

Compatible with Cisco’s QSFP-100G-LR4-S, 6COMGIGA’s 100GBASE-LR4 QSFP28 Optical Module transmits 100GBase-LR4 signals over a pair of standard single-mode fiber (SMF) and duplex LC connectors over distances of up to 10 km. The module complies with IEEE 802.3 100GBASE-LR4, SFF-8665, and SFF-8636 standards, supports an I2C interface, and provides digital diagnostics for real-time monitoring of operating parameters via the QSFP28 MSA specification.

 

Advantages of 100GBASE-LR4 in Long Distance Transmission

 

Here are some of the advantages of 100GBASE-LR4 modules in long-distance transmission:

 

Extended Transmission Distance without Performance Loss

100G LR4 module is planned for long-haul data transmitting, and the transmission type can assist 10km Single-mode fiber transmission. As such, for applications spanning cities or regions, such as data centers or critical infrastructure between locations, the module prevents signal deterioration over long-distance transmission and ensures the integrity of the link distance with it.

 

Low Latency Enables High-Speed Networks

Latency is critical in modern networks, especially in real-time data processing, video streaming, and online gaming which are requiring fast response times. 100G LR4 modules optimize the user experience by reducing the time data travels through the network, providing superior performance support for latency-sensitive applications.

 

High Bandwidth for Big Data Transmission

The module has enough capacity to support large-scale data traffic, ensuring that data is transmitted efficiently and smoothly across the network. For data centers and cloud service providers, fast processing and managing massive data are critical factors in staying competitive.

 

Improve Network Reliability and Scalability

The 100G LR4 module is scalable and can easily adapt to future network growth. Supporting higher transmission rates and longer distances as data demand continues to increase, the module is a solution that flexibly adapts to changes in network architecture.

 

An Economical Solution for Long-Term Growth

The initial cost of the 100G LR4 module is a little more expensive but in the long term, it is definitely worth paying. The high-speed, long-distance transmission improves the reliability of internal signaling relay equipment and reduces the cost of operation and maintenance. For its expansion of the network and upgrading technology, 100G LR4 module is enough to satisfy current needs and an investment with a vision.

Application Scenarios of 100G LR4 Module

 

6COMGIGA’s QSFP28 LR4 modules are mainly used in three major scenarios: 100GbE switch direct connectivity in data centers, direct connectivity deployments in 5G wireless networks and telecommunication domains, and long-distance transmission applications for telecommunication carriers.

 

In data centers, the 100GbE switch direct connect architecture is typically based on the Spine-Leaf network topology, which is a standard design for modern data centers, optimized for large-scale, high-speed data transmission.

 

Core Layer: In OSI models, The core layer is responsible for traffic management and scheduling of the entire network, so the core switches require high bandwidth and long-distance connectivity. 100G LR4 modules support high-speed data transmission of up to 10 kilometers, ensuring low latency and high stability between the core layers to ensure efficient network operation.

 

Spine Layer: This module connects the Spine layer to the core layer using 100G LR4 modules to meet the long-distance data transmission needs. The Spine layer can efficiently transmit data to the core layer, supporting large-scale data processing and fast transmission.

 

Leaf Layer: The Leaf layer is usually connected to the Spine layer via 100G LR4 modules, while short-distance lateral connections use 100G SR4 modules. Although the Leaf layer mainly handles short-distance transmissions, when long-distance connections are required, the LR4 module can provide sufficient bandwidth and stability to ensure smooth data transmission from the server layer to the Spine layer.

 

The 100G LR4 module is a high bandwidth long-distance connection that ensures large-scale data can be processed and forwarded efficiently in the core and Spine layer of the network while maintaining low latency and high reliability. It shines in large physical distances (high load scenarios within big data centers and WANs)

 

Conclusion

 

The 100G LR4 module offers 10 km of connection over Single mode fiber which is the best in class to have a seamless connectivity between campus backbone and core layers most effectively. The 100G LR4 module is the ultimate choice for data center interconnection between regions and high-traffic applications. This offers 100Gbps blazing fast transmission rates, refining and boosting network speed.

 

In data centers, 100G modules are the key to building efficient network architectures. 6COMGIGA’s 100G modules provide stable high-speed connectivity to meet any application requirement, whether the core, aggregation, or access layers. However, the needs of each data center are different, and a standardized solution may not fully meet your specific requirements. For instance, you may need to use 40G optics in QSFP28 equipment ports to get four 10G transmission breakout, then will have the choice: 1. QSFP-40G-SR4, SFP-10G-SR and a MTP to 4x LC duplex OM3/OM4 MMF. 2. a 40G QSFP+ to 4x 10G SFP+ DAC cable. To make the best choice, welcome to contact us for consult.
