Q1: What is DR1 in 100G QSFP28 modules?
DR1 refers to a single-lane 100G transmission over short-reach single-mode fiber using PAM4 modulation.

Q2: What is the maximum distance supported?
It supports up to 500 meters over single-mode fiber (SMF).

Q3: What connector type does it use?
It uses a duplex LC optical interface.

Q4: Does it support real-time monitoring?
Yes. It includes DDM for monitoring optical power, voltage, and temperature.

Q5: Is it compatible with standard QSFP28 ports?
Yes. It follows QSFP28 MSA standards for broad compatibility.

Q6: Where is it typically used?
It is commonly used in data centers, cloud infrastructure, and telecom networks for short-reach 100G links.
