What is the difference between LR4 and ER4 100G optical modules?

100G LR4 and ER4 modules use similar four-wavelength LAN-WDM architectures, but they are typically optimized for different transmission distances. LR4 modules are generally designed for around 10km links, while ER4 variants extend transmission capability for longer distances with enhanced optical performance.

Why does this module use LAN-WDM technology?

LAN-WDM technology combines multiple optical wavelengths within the 1310nm band to transmit multiple high-speed channels over a single fiber pair. This allows 100Gb/s transmission while maintaining compatibility with standard duplex single-mode fiber infrastructure.

Can this QSFP28 module support both Ethernet and OTU4 applications?

Yes. The module supports dual-rate operation for both 100GE Ethernet and OTU4 optical transport applications, making it suitable for networks that require flexible protocol deployment.

What role does FEC play in this transceiver?

FEC improves transmission reliability by detecting and correcting certain signal errors during communication. It helps maintain stable performance in high-speed optical links, especially in demanding network environments.

Is this module compatible with standard QSFP28 equipment?

Yes. The module follows the QSFP28 form factor and uses a CAUI-4 electrical interface, making it compatible with network devices that support 100G QSFP28 optical transceivers.
