FAQs

Q: What fiber type is this DCM intended for?
A: It is designed for Enhanced LEAF (G.655) single‑mode fiber spans.

Q: Can it be used in the C‑band DWDM systems?
A: Yes. It targets the C‑band commonly used in long‑haul and metro DWDM.

Q: Does the DCM require power or management?
A: No. It is a passive optical component and does not require power.

Q: How do I choose the correct compensation value?
A: Select the module whose ps/nm rating offsets the accumulated dispersion for your span at the operating wavelength.
