DWDM - Dense Wavelength Division Multiplexing

Maximise Your Fibre Investment with Wavelength Multiplexing

Dense Wavelength Division Multiplexing (DWDM) is an optical transport technology that combines multiple data signals onto a single optical fibre by assigning each signal a different wavelength (colour) of laser light. This allows service providers and enterprises to dramatically increase the capacity of their existing fibre infrastructure without laying new cables.

Why EBB DWDM?

Massive Scalability

A single fibre pair can carry 96 or more independent wavelengths, each supporting up to 400Gbps, providing aggregate capacities in the tens of terabits per second. Capacity is added incrementally by lighting additional wavelengths.

Protocol Flexibility

Each wavelength operates independently and can carry any protocol - Ethernet, Fibre Channel, OTN, or SDH - making DWDM ideal for converged transport networks that serve diverse application requirements.

Non-Disruptive Growth

New wavelengths can be provisioned and activated without affecting existing services on the same fibre, enabling in-service capacity upgrades that align with your growth trajectory.

Cost-Effective High Bandwidth

By maximising the utilisation of existing fibre assets, DWDM delivers the lowest cost per gigabit for high-bandwidth connectivity, reducing the need for expensive new fibre builds.

EBB DWDM Network

EBB operates a DWDM-enabled optical backbone across Peninsular Malaysia, connecting major data centre hubs and business districts. Our platform supports both managed wavelength services and integration with customer-owned DWDM equipment for maximum flexibility.
