1.7.2020 08:15:14 CEST | Business Wire | Press release
Kyoto Semiconductor Co., Ltd. (headquartered in Kyoto, Japan) has developed a high-speed photodiode KP-H KPDEH12L-CC1C to support 400Gbps transmission systems that use PAM4 (Pulse Amplitude Modulation 4) inside and between data centers. With the introduction of this InGaAs photodiode, the company is continually supporting the increasing speeds and capacity requirements for transmission systems in 5G networks and beyond. Mass production will start in November, 2020.

KP-H KPDEH12L-CC1C main features
(1) High-speed
The size of the carrier on which the PD is mounted, and the width and length of the high frequency electrode pattern placed on the carrier are optimized using an electromagnetic simulation (Note 2). As a result, we have achieved the world’s top class 400Gbps and 40GHz as a frequency band with an integrated transimpedance amplifier. The KP-H photodiode has passed Telcordia GR-468-Core, which is the standard reliability test for communication equipment.
(2) Easy implementation
KPDEH12L-CC1C is mounted on a carrier that is optimally designed to achieve high frequency. A condenser lens is integrated on the backside of the photodiode (Note 3), allowing the incoming light to collect in the light absorption area, and makes it easy to align the optical fiber with PD. The PD chip is mounted on a carrier twice as big as the chip itself.
Background of development
Currently, we have achieved transmission speeds of mainly 100Gbps by bundling 4 lanes of 25Gbps. However, there are growing demands in the market for 400Gps to 800Gbps transmission speeds. The Institute of Electrical and Electronics Engineers (IEEE) set the standard of PAM4 that corresponds with 4-bit signal to one modulation. The transmission speed per PD reaches 50Gps (= 400Gps/4 lanes/2 (PAM4)). The transmission bandwidth required for the PD to achieve this speed will be 35~40GHz.

About Kyoto Semiconductor
Kyoto Semiconductor was established in 1980 in Kyoto as a dedicated manufacturer of semiconductors. The semiconductors manufactured offer superlative performance and precision, suited for use in optical transmission. They are manufactured end-to-end, including pre- and post-processing, and together with Kyoto Semiconductor’s unique packaging technology, at our location in Japan and made available to customers around the world. Kyoto Semiconductor leads the industry with world-standard technologies for optical device solutions based on Japanese quality and attention to production detail.
Notes
1) 4- level modulation method 8PAM 4 (Pulse Amplitude Modulation 4)
Instead of mounting 2-bit information {0, 1} for one modulation, the method mounts 4-bit information {0, 1, 2, 3}. This method allows transmission of twice as much information as conventional method.
2) Carrier
The patterns with little attenuation in the high-frequency are formulated on the surface of the board on which the PD is mounted. The dimension of the carrier is 0.6 x 0.48 x 0.25 t
mm.
3) Condenser lens
The figure shows a schematic view of the PD chip. A condenser lens is built into the surface where the light enters, and is focused and collected on a small light absorption layer.

The Only AI Crypto Lead Prioritization Solution Built With Law Enforcement, for Law Enforcement: Elliptic Launches Pulse24.9.2026 15:15:00 CEST | Press release
Pulse delivers actionable leads in seconds, no crypto expertise required, enabling decisions in the field Elliptic, the global leader in on-chain risk, today launched Pulse. Pulse puts crypto lead prioritization directly in the hands of every frontline law enforcement and government officer. Crypto now touches every part of law enforcement, from the patrol officer on the street to the detective assigned to investigate the case. Pulse gives each of them a quick, accurate financial summary and a starting point: whether that's a crypto address on a suspect's phone, in a scam ATM victim's receipt, uncovered during a vehicle or pocket search, or found at the scene of an overdose, an arrest, or a seizure. An officer can input anything that looks like a wallet address or transaction hash. Pulse identifies it, reasons over the result, and returns a summary in plain language, enough for the officer to decide on the spot whether the case needs escalation. If a case needs further investigation, o
Just 4.7% of Financial Institutions Continuously Update Their Compliance Monitoring and Controls as Risk Changes, New Research Finds24.9.2026 15:04:00 CEST | Press release
As financial crime threats, regulations and transaction volumes evolve dynamically, most compliance programs remain built around periodic review SymphonyAI, a global leader in vertical AI product platforms, and AML Intelligence, the leading source of news and insight for the financial crime compliance community, today released the FinCrime Frontier 2026–27 Report, finding that most financial institutions still rely on periodic review cycles to manage financial crime risk, even as the threats and regulations they are meant to track continue to evolve dynamically. Based on the perspectives of more than 200 financial crime and compliance leaders, including senior leaders from major global financial institutions, the research finds that just 4.7% of financial institutions continuously update their compliance monitoring and controls as risk changes, while 56.8% have not adopted always-on compliance monitoring at all, are only exploring it, or remain at an early, pilot-stage level. The findi
