5. FAQ

What is a DWDM Multiplexer?

A DWDM multiplexer is used in wavelength-division multiplexing systems to manage multiple optical wavelength channels within the same fiber infrastructure. The GracyFiber product family supports C-band ITU-T channels from C11 to C64.

What is a DWDM OADM?

An Optical Add-Drop Multiplexer (OADM) is used in a wavelength-routed optical network where selected wavelength channels need to be added to or dropped from an optical path. Specific add/drop configurations for this product family should be confirmed according to the required wavelength plan.

Which DWDM wavelengths are available?

The supplied documentation specifies ITU-T C-band channels C11–C64 and states that customized wavelength configurations are available.

What channel count and channel spacing are available?

The current product materials do not provide confirmed channel-count or channel-spacing values. Please contact GracyFiber with your required ITU channels and network architecture.

8. Detailed Product Description

The GracyFiber DWDM Multiplexer & OADM series is developed for wavelength management in high-capacity optical networks. The product family operates across the ITU-T C-band channel grid from C11 to C64, allowing network designers to select standard or customized wavelength configurations according to system requirements.

Within a DWDM system, wavelength multiplexing allows multiple optical channels to share fiber infrastructure. OADM configurations extend this architecture by providing access to selected wavelength channels at intermediate network locations. The exact wavelength and port configuration can therefore be selected according to the optical network topology.

The supplied product specifications emphasize low insertion loss, high isolation, low PDL, and low ripple. These characteristics are important in multi-wavelength optical networks because each passive component becomes part of the overall optical link budget and channel-management architecture. Numerical limits for these parameters are not included in the supplied documentation and should therefore be confirmed for each configuration.

Both compact and rack-mount formats are documented. This allows the product family to address different deployment environments, from equipment-level wavelength management to centralized optical distribution systems.

The listed applications cover metro, regional, backbone, 5G transport, data center interconnect, enterprise, campus, and CATV networks.

For B2B projects, the key configuration information should include the required ITU channels, add/drop architecture, channel count, package format, connector interface, and target optical specifications before quotation.

9. Application Scenario

Application 1 — Metro and Regional DWDM Networks

Metro and regional networks may need multiple optical wavelength channels transported over shared fiber infrastructure.

A DWDM multiplexer can be used to organize the required C-band wavelength channels, while an OADM configuration can provide access to selected wavelengths at intermediate network locations.

The C11–C64 wavelength support allows the configuration to be defined according to the network wavelength plan.

Application 2 — 5G Fronthaul / Midhaul / Backhaul

5G transport networks can require multiple optical connections between network locations while making efficient use of available fiber.

The DWDM MUX/OADM series is explicitly specified for fronthaul, midhaul, and backhaul applications, providing wavelength-management capability for these optical transport architectures.

Application 3 — Data Center Interconnect

Data center interconnect networks can use DWDM wavelength channels to transport multiple optical links between sites.

The GracyFiber DWDM Multiplexer & OADM family provides C-band wavelength management in compact or rack-mount configurations for DCI architectures.
