2.5Gbps InGaAs APD Photodiode Chip‑ Chips for Optical‑Fiber‑Communication and OTDR Sensing

The 2.5Gbps InGaAs APD photodiode chip is a front‑illuminated planar‑structure bare die with separated PN electrodes. Equipped with a 50‑μm‑diameter photosensitive area, it delivers ample light‑receiving aperture, fast‑response capacity and stable wavelength‑operating performance.
This avalanche photodiode features low‑bandwidth noise and excellent side‑mode suppression ratio for premium‑grade spectral performance. It provides steady output characteristics for high‑speed dynamic signal reception and its robust die‑structure supports varied packaging solutions.
Operating within the ‑40℃~+85℃ wide‑temperature range, the bare die is compatible with customized control circuits for high‑speed optical‑signal acquisition. It is available as unpackaged chip‑die and well‑suited for fiber‑optic hardware, OTDR instrument modules, optical network units and scanning‑imaging equipment.
D‑10A40F‑01 10Gbps InGaAs APD Photodiode Chip‑ High‑Speed Receiver Chip for 5G‑Front‑Haul and 10G‑PON

Model D‑10A40F‑01 is a mesa‑type front‑illuminated avalanche photodiode bare die optimized for the 1550‑nm telecommunication band, with a 40‑μm photosensitive‑surface diameter.
Working under the photoconductive mode, the component specializes in high‑speed, low‑noise optical detection. It comes with high responsivity, low parasitic capacitance, ultra‑low dark‑current and low noise‑equivalent power to enhance receiving sensitivity and signal quality. Its low excess‑noise factor improves detection accuracy, and it is supplied in bare‑die form.
The chip is ideal for 10Gbps optical transceivers, 10G‑PON passive optical‑network hardware, 5G radio‑unit front‑haul modules, LiDAR ranging, free‑space optical communication, remote sensing, industrial machine‑vision and optoelectronic security‑defence systems.
