Questions & Answers

Q: What is the difference between FR1, DR1, and LR1?

A：DR1: 500m short-range, lower power consumption, suitable for inter-cabinet connections within data centers;
FR1: 2km medium-to-short range, balancing distance and cost, ideal for campus and adjacent data center interconnects;
LR1: 10km long-range, higher power consumption and cost, used for long-distance interconnects across campuses.
This FR1 is the cost-effective preferred solution for data center connectivity within 2km.
