FAQs

Q: What is the maximum supported distance?
A: Up to 70 km over low-loss OS2 single-mode fiber, subject to link budget.

Q: Can it interoperate with other vendors’ CWDM optics?
A: Yes at the optical layer when wavelength, speed, and CWDM grid match; host acceptance depends on platform coding policies.

Q: Is a CWDM mux required?
A: Not required for single-wavelength links, but needed to multiplex multiple CWDM channels on the same fiber pair.

Q: Does it support DOM/DDM?
A: Yes, on compatible hosts that expose digital diagnostics.

Q: What connector type is used?
A: LC duplex connectors on single-mode fiber.
