What is the difference between PSM4 and LR4 100G optical transceivers?

PSM4 modules use four parallel single-mode fibers to transmit and receive data, while LR4 modules use wavelength multiplexing technology over duplex single-mode fiber. PSM4 provides a simpler optical architecture and is often used for cost-effective 100G data center links.

Why does the PSM4 module use MPO-12 connectors?

MPO-12 connectors provide high-density parallel fiber connectivity by integrating multiple fiber channels into a single interface. This makes them suitable for applications requiring multiple optical lanes, such as 100G PSM4 transmission.

Can this module support transmission up to 10km?

Yes. The 100G QSFP28 PSM4 transceiver is designed for up to 10km transmission over single-mode fiber when used with compatible MPO-12 fiber cabling systems.

What is the role of the CDR function in this transceiver?

The Clock Data Recovery (CDR) circuit helps restore timing information from high-speed data signals, improving signal quality and maintaining stable transmission performance in 100G optical links.

Is this PSM4 transceiver compatible with QSFP28 network equipment?

Yes. The module follows QSFP28 MSA standards and supports compatible 100G Ethernet switches, routers, and networking equipment with QSFP28 optical ports.
