What is the transmission distance of the 100G SFP56-DD LR1 transceiver?

The 100G SFP56-DD LR1 module supports transmission distances of up to 10km over G.652 single-mode fiber, making it suitable for metro-access links, data center interconnects, and long-distance Ethernet connections.

What is the difference between 100G SFP56-DD FR1 and LR1 modules?

The main difference is transmission reach. FR1 modules are designed for shorter links up to approximately 2km, while LR1 modules extend the reach to 10km using optimized optical components while maintaining the compact SFP56-DD form factor.

Why does the LR1 module use a cooled EML transmitter?

A cooled EML TOSA provides improved wavelength stability and optical performance compared with lower-power laser technologies. It is commonly used in longer-reach optical modules where precise wavelength control and reliable transmission are required.

Is this module compatible with existing single-mode fiber cabling?

Yes. The transceiver uses a standard Duplex LC optical interface and is designed for G.652 single-mode fiber, allowing integration with widely deployed SMF cabling infrastructure.

Does the module support FEC functions?

Yes. The module supports KP-FEC, while KR-FEC support depends on the host equipment and system implementation. FEC improves error correction capability and helps maintain reliable high-speed transmission.
