FAQs

Q: Is this compatible with OC-48/STM-16 DWDM ports on my switch or router?
A: Yes, if the port supports DWDM SFP optics at OC-48/STM-16 rates. Confirm device compatibility.

Q: Is the wavelength adjustable?
A: No. It is a fixed-wavelength unit aligned to the ITU DWDM grid.

Q: What interface does it use?
A: LC duplex connectors on single-mode fiber.

Q: How far can it go?
A: It is intended for long-haul scenarios; actual reach depends on link budget, amplifiers, and dispersion management.
