With the increasing demand for high-speed data communications, more and more telecom service providers are adopting 100Gbps solutions to address the trend, with QSFP28 LR4 modules being the most inquired amongst the 100G modules family. So, it's about time that we set straight the problems and questions about them.
 

Currently, there are two types of QSFP28 LR4 10KM modules in the market: one is often referred to as CWDM QSFP28 LR. This type of QSFP28 LR modules features 4 CWDM channels, with each being 1270nm;1290nm; 1310nm and 1330nm respectively. This type is designed to meet the demand for dense data inter-connecting in data centers.
 

The second 2 type is called LAN-WDM QSFP28 LR4. They comprise 4 DWDM channels, which is exactly what differentiates them from the first type(CWDM QSFP28 LR4). LAN-WDM QSFP28 modules outperform CWDM QSFP28 and are more often used in SDH networks, hence more costly.
 

C-LIGHT can provide both types of 100G QSFP28 modules. Should you have further questions, please don't hesitate to email us at daniel.zhang@c-light.com or visit our website to find out more about our products and services.
