FAQs

Q: When should I choose a 350 ps/nm DCM over 200 ps/nm?
A: Use higher compensation values for longer spans or where total accumulated dispersion is greater.

Q: Is it suitable for 10G, 40G, and 100G systems?
A: Yes. It is passive and multi‑rate compatible; verify overall link design for OSNR and latency targets.

Q: Does it require any configuration?
A: No. It is a fixed, passive module and requires no configuration.

Q: What connectors does it use?
A: LC/UPC on both input and output ports.
