Ultra-High Density Polarization-Maintaining Thermally Insulated Arrayed Waveguide Grating (PM AAWG Module) - 32 To 96 Channels
1. Product Overview
GRACYFIBER's polarization-maintaining, heat-free arrayed waveguide grating (PM AAWG) module is an ultra-high-density passive multiplexer/demultiplexer based on advanced planar optical waveguide (PLC) technology. Designed for next-generation high-capacity optical networks, this module can simultaneously process dozens to 96 independent wavelengths in the C-band (1525–1565 nm) and supports ultra-fine channel spacing down to 50 GHz (0.4 nm). By seamlessly integrating silica waveguide technology with high-precision polarization-maintaining (PM) fiber pigtails, it not only provides excellent flat-top or Gaussian filtering performance but also maintains extremely stable polarization states across all channels. It is the unparalleled ultimate wavelength management engine for 100G/400G/800G coherent communications, data center interconnect (DCI), and precision test platforms requiring stringent polarization control at extreme channel densities.

(Designed to address backbone network capacity limitations and the pain points of polarization dispersion in coherent communication)
Features: Breakthrough 32CH to 96CH ultra-high density architecture
Pain Points Solved/Value Boost: Supports multiple ITU Grid channel spacing options at 50GHz, 100GHz, and 150GHz. At 50GHz spacing, a single fiber can achieve multiplexing and demultiplexing of up to 96 independent wavelengths. This allows telecom operators and cloud service providers to dramatically increase the throughput of their existing optical networks by tens of times without increasing any physical fiber optic cabling costs.
Features: Superior Polarization Preservation (PM) Capability and Planar Optical Waveguide (PLC) Technology
Pain Points Solved/Value Boost: Unlike standard AAWG, our modules integrate high-precision polarization-maintaining fiber at each I/O port. This ensures that the linear polarization state of the light wave remains extremely high after passing through complex multiplexing/demultiplexing arrays. This completely eliminates the crosstalk and bit error risks associated with polarization multiplexing in high-speed coherent transceivers.
Features: Dual support for Flat-top and Gaussian filtering technologies
Pain points addressed/value: Offers two customized band filtering profiles: Gaussian provides the industry's lowest port insertion loss, suitable for extreme distance transmission; Flat-top provides a wider signal passband, perfectly tolerating wavelength drift caused by long-term operation of active lasers, greatly improving the fault tolerance of dense wavelength division multiplexing systems.
Features: Ultra-low insertion loss and high channel uniformity
Solved pain points/value: Through sophisticated athermal packaging and optimized internal optical path, it achieves extremely low overall insertion loss across up to 96 channels while ensuring excellent power consistency between channels. Combined with superior isolation between adjacent channels, it provides a pristine signal-to-noise ratio (OSNR) environment for high-order modulation formats such as 16-QAM and 64-QAM.
Features: Flexible and compact packaging with standard 1U rack-ready configuration
Pain points addressed/value: Despite the highly complex waveguide array integrated internally, we still offer compact custom housing options and a standard 19-inch 1U rack-ready form factor, perfectly suited to the stringent U-space constraints of modern high-density central office (CO) and enterprise data centers.
3.Applications
- Coherent Optical Transport: Polarization multiplexing and massive wavelength routing for 100G/400G/800G and higher speed DWDM systems.
- Data Center Interconnect (DCI): Providing point-to-point, high-capacity, zero-power wavelength division multiplexing (WDM) extension for hyperscale cloud providers.
- Dense Optical Communication Networks: Physical layer backbone reconfiguration for backbone and metropolitan area core networks.
- Optical Amplifier Systems (EDFA): Achieving lossless signal relay across the entire C-band in conjunction with high-power fiber amplifiers.
- Polarization-Sensitive Optical Platforms: Wavelength allocation for high-end LiDAR and quantum secure communication backbone nodes.
- Optical Test & Measurement: Reference-grade multi-channel, stable polarization source splitters for laboratory and production lines.
