Frequently Asked Questions

What is WDM technology?

Wavelength Division Multiplexing (WDM) is a technology that multiplexes multiple optical carrier signals onto a single optical fiber by using different wavelengths (colors) of laser light.

What's the difference between CWDM and DWDM?

CWDM uses wider channel spacing (20nm) and is cost-effective for shorter distances. DWDM uses narrow spacing (0.8nm or less) and supports higher capacity over long-haul networks.

Do you offer customization services?

Yes, WDMLight provides personalized customization services to meet specific customer requirements in terms of channel count, form factor, and integration.

What kind of support do you provide?

We offer real-time customer service, technical documentation, firmware updates, and engineering support for deployment and troubleshooting.
