High Density Polarization Maintaining Thermally Insulated Arrayed Waveguide Grating PM AAWG Module

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.

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.

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.

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.

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.
