Kyoto Semiconductor Co., Ltd. optical device solution manufacturer with technologies and Japanese quality, has announced KP-A avalanche photodiode (APD), KPDEA003-T. The new product achieved high sensitivity, high gain, and low noise suitable for OTDR (Optical Time Domain Reflectometer) that is essential in deploying optical fiber networks.
As the optical fiber deployment is increasing in accordance with the expansion of 5G networks, there have been growing requests for high sensitivity, high gain, and low noise in APDs used in OTDRs to quickly detect faults in optical fibers.
KP-A avalanche photodiode “KPDEA003-T” was developed for sensing optical fibers. This product is a module in which a single-mode fiber with an SC optical connector is coaxially integrated so that it is easily connected to the optical device. Compared to Kyoto Semiconductor’s existing product, KPDEA003-T has achieved higher sensitivity with a multiplication of 2 times*4, and the noise is a fifth as low*5 thanks to the company’s unique wafer structure.
These characteristics allow “KPDEA003-T” to sense the weak light that can not be detected with PIN photodiodes or existing APDs. The product is expected to be used not only in testing optical fibers but also in medical or analytical equipment.
Tsuneo Takahashi, President, and CEO, Kyoto Semiconductor, says, “There has been strong demand for high sensitivity APD suitable for OTDR among test equipment manufacturers worldwide. We expect our new APD, KPDEA003-T, to meet the requirements with its world-class performance.”
