FS 100G Dual Rate Module Applications

Data Center

100G dual-rate modules play a critical role in data centers, especially for connecting spine and leaf layers. These 100G QSFP28 dual rate modules allow data center administrators to achieve adaptable connectivity without hardware changes. For example, by replacing modules with 100G QSFP28 ports with 40/100G SWDM4 modules, data centers can achieve efficient 40G connectivity while preparing for future 100G demands.

Service Provider Networks

Service providers must meet increasing bandwidth demands while maintaining reliability. 100G dual-rate modules enable service providers to offer high-speed connections at different network levels from local short-distance links to long-haul backbone network connections. For instance, QSFP 100G SR4 modules work well for short distances, while LR4 and 100G ER4 modules are suitable for medium to long-distance and long-distance connections. The dual-rate feature provides flexibility for tailored solutions. In optical transport network (OTN) scenarios, 100G/112G dual rate modules can meet higher bandwidth and reliability requirements.

Enterprise Campus Networks

Enterprise campus networks often require diverse connections, from short-distance office links to long-distance inter-building connections. 40/100G SWDM4 modules and 100/112G modules (like SR4, LR4, ER4) offer multiple connectivity options for various distances and performance needs. Enterprises can choose the appropriate modules for specific scenarios, creating cost-effective connectivity solutions. This simplifies network deployment and ensures adaptability to evolving business requirements.
