FS 40/100G QSFP28 SWDM4 Optical Transceiver Overview

In the fast-paced world of networking, the demand for high-speed connectivity continues to surge. Enter the 40/100G SWDM4 module, a game-changing solution that combines dual-rate compatibility with the efficiency of Short Wavelength Division Multiplexing (SWDM) technology. This compact yet powerful module offers a wealth of benefits, from increased bandwidth capacity to cost-effective infrastructure upgrades.

What is FS 40/100G SWDM4 Module?

The FS 40/100G SWDM4 dual-rate module is a specialized type of optical transceiver module designed to support both 40 Gigabit Ethernet (40GBASE) and 100 Gigabit Ethernet (100GBASE) transmission rates using Short Wavelength Division Multiplexing (SWDM) technology. This dual-rate module is capable of transmitting and receiving data over four wavelengths (hence the "4" in SWDM4) within the short wavelength range, typically using multimode fiber (MMF) infrastructure. It allows for the simultaneous transmission of multiple data streams, effectively increasing the overall bandwidth capacity of the optical link. The working principle is as follows:

What are the Advantages of FS 40/100G SWDM4 Module?

In the realm of network infrastructure, the adaptability and versatility of FS 40/100G SWDM4 Module play a pivotal role in meeting the evolving demands of modern connectivity. Here are some of its advantages:

Dual-rate Compatibility: The module supports both 40 Gigabit Ethernet (40GBASE) and 100 Gigabit Ethernet (100GBASE) transmission rates, providing versatility and future-proofing for network upgrades.

Increased Bandwidth: SWDM technology enables the transmission of multiple data streams over a single optical fiber, effectively increasing the bandwidth capacity of the link compared to traditional single-wavelength solutions.

Utilization of Existing Infrastructure: SWDM4 modules can leverage existing multimode fiber (MMF) infrastructure, allowing for cost-effective upgrades in environments where MMF is already deployed.

Reduced Fiber Requirements: By transmitting multiple data streams over a single fiber, SWDM4 modules help reduce the number of fibers needed for high-speed connections, optimizing space and simplifying cable management.

Compatibility with QSFP28 Form Factor: SWDM4 modules typically use the QSFP28 form factor, which is widely adopted in data centers and enterprise networking equipment, ensuring compatibility with existing hardware and infrastructure.

Interoperability: SWDM4 modules are designed to be interoperable with other SWDM-enabled devices, facilitating seamless integration into existing networks and interoperability with future SWDM-based solutions.

Cost-effectiveness: The ability to support multiple transmission rates and utilize existing fiber infrastructure helps reduce deployment costs and total cost of ownership, making SWDM4 modules a cost-effective solution for high-speed networking.

How to Upgrade the Rate of FS 40/100G SWDM4 Modules?

When using a dual-rate 40/100G module in a 40/100G switch port (depicted by the green box on the left), it's still compatible with a native 40G module plugged into an older switch featuring a single-rate 40G port (illustrated by the orange box on the right). To ensure compatibility, the dual-rate port on the left is configured to operate at 40G mode within the switch software (as indicated by the red outline in the diagram).

When you're ready to upgrade the other end of the connection, simply replace the 40G switch with a new one supporting 100G QSFP28 ports, such as N5860-48SC. Insert the new 40/100G module and configure the switch software on both ends to run the port at 100G. With these steps completed, the upgrade is successfully executed.

Conclusion

In summary, the FS 40/100G SWDM4 module stands as a versatile and cost-effective solution for modern networking challenges. With its dual-rate compatibility, enhanced bandwidth capacity, and seamless integration capabilities, it offers unprecedented flexibility and efficiency in high-speed connectivity. As networks continue to evolve, this innovative module promises to play a pivotal role in driving performance and scalability across various industries and applications.
