What is the main application difference between DR1 and LR1 optical transceivers?

100G DR1 modules are optimized for short-distance single-mode fiber links, typically up to 500m, making them suitable for data center and campus environments. LR1 modules are designed for longer transmission distances, usually up to 10km, for wider-area network applications.

Why does the 100G QSFP28 DR1 module use PAM4 modulation?

PAM4 modulation increases transmission efficiency by carrying more data per symbol compared with traditional NRZ signaling. It enables 100Gb/s optical transmission while maintaining compatibility with compact QSFP28 form factors.

Can this module be used with existing single-mode fiber cabling?

Yes. The transceiver uses standard single-mode fiber and a Duplex LC optical interface, allowing integration with existing SMF infrastructure commonly deployed in data centers and enterprise networks.

What monitoring functions does DDM provide?

Digital Diagnostic Monitoring allows users to monitor key operating parameters such as module temperature, supply voltage, transmit optical power, and receive optical power, helping simplify network maintenance and troubleshooting.

Is this transceiver compatible with standard QSFP28 ports?

Yes. The module follows QSFP28 MSA specifications and is designed for compatible 100G Ethernet switches, routers, and networking equipment supporting QSFP28 optical interfaces.
