AAWG DWDM Multiplexer, 32–96CH, 50/100/150 GHz
GracyFiber AAWG DWDM Multiplexer is a high-density passive wavelength-division multiplexing component designed for C-band optical networks. Using an athermal arrayed waveguide grating architecture, the module does not require external electrical power or active temperature-control circuitry for its wavelength-routing function.
The source documentation specifically lists low insertion loss, low PDL, high isolation, ITU-T G.694.1 accuracy of ±0.05 nm, and Telcordia GR-1221.
Metro, long-haul, and DCI applications are identified in the supplied product description, while line monitoring, WDM networks, telecommunications, and fiber optical amplifiers are listed in the application section.
An AAWG DWDM Multiplexer is a passive wavelength-division multiplexing device based on an athermal arrayed waveguide grating architecture. The supplied GracyFiber product is designed for high-density C-band wavelength multiplexing without requiring an external power supply or active temperature-control circuit.
Available channel counts depend on the selected spacing:
The supplied specification provides both Flat-top and Gaussian configurations for selected AAWG versions, with different passband, insertion-loss, ripple, and isolation characteristics.
For example, the 100 GHz specification contains both Flat-top and Gaussian performance sets. Selection should therefore be based on the required optical passband and system specification.
The supplied specification lists:
ITU Grid C13–C64 or customized center wavelengths.
The documentation also states an ITU-T G.694.1 wavelength accuracy of ±0.05 nm.
The supplied specification lists LC/UPC or customized connectors and multiple package dimensions. For other connector or mechanical requirements, please provide the required configuration to GracyFiber for technical review.

The GracyFiber AAWG DWDM Multiplexer is designed to increase wavelength capacity over a single optical fiber by providing a dense set of precisely controlled C-band wavelength channels. Its arrayed waveguide grating architecture supports channel spacing down to 50 GHz, allowing as many as 96 channels to be integrated into a single wavelength-multiplexing platform.
The athermal design is passive and avoids the requirement for an external power supply or active thermal-control circuitry in the optical module. The supplied documentation specifies C-band operation from 1525 nm to 1565 nm and channel configurations from 32CH to 96CH.
Different spectral profiles are available according to channel-spacing requirements. The supplied specification includes 150 GHz Flat-top, 100 GHz Flat-top, 100 GHz Gaussian, and 50 GHz Flat-top configurations. Each configuration has its own insertion-loss, passband, isolation, and ripple specifications, allowing the optical design to be selected according to system requirements.
For example, the 100 GHz Gaussian version is specified with a maximum port insertion loss of 3.8 dB, while the 50 GHz Flat-top version supports 80, 88, or 96 channels with a maximum port insertion loss of 6.0 dB.
The module also provides a listed 1310 nm special-port configuration, low PDL, defined channel uniformity, return loss, and directivity. Multiple fiber, connector, and mechanical package configurations are provided in the supplied specification.
This makes the AAWG suitable for high-channel-count WDM links where fiber capacity, wavelength density, and passive optical operation are key design considerations.
In metro or long-haul optical networks, the AAWG can provide high-density wavelength multiplexing so that multiple optical channels can share an existing fiber infrastructure.
The supplied documentation specifically identifies metro and long-haul transmission as target scenarios for the module.
DCI links require increasing optical capacity between data-center locations. A high-channel-count AAWG allows multiple DWDM wavelengths to be carried over the same fiber pair, with channel spacing available down to 50 GHz.
The product description explicitly identifies Data Center Interconnect (DCI) as an application.
The specification includes a special monitor / 1310 nm port configuration, while the application information identifies both line monitoring and fiber optical amplifiers as use cases.
Exact monitor-port implementation should be confirmed according to the selected configuration.
GracyFiber supplies passive optical components for wavelength management, fiber connectivity, photonics, and optical communication systems.
