It maintains constant performance, even during communication between a fixed object and others that rotate 360 degrees.
In addition to short-range board-to-board communication, this optical transceiver is ideal for data communication equipment with rotating mechanisms, such as robotic arms and omnidirectional cameras. This new solution overcomes the limitations of traditional slip rings*, offering a reliable and maintenance-free alternative.
Product samples and evaluation kits will be available from Tuesday, October 1st, to domestic and international manufacturers in sectors such as transportation, industrial machinery, medical devices, cameras, connectors, and many more.
* Slip ring: a connector that transmits electrical signals between a rotating and a stationary object. In systems with rotating mechanisms, they allow communication without cable tangling.
Product Overview:
The P16548-01AT optical transceiver integrates an optical transmitter that converts electrical signals into optical signals and an optical receiver that converts them back into electrical signals. These components are housed in a compact package, facing each other along the same optical axis. This configuration enables bidirectional full-duplex communication at up to 1.25 Gbps, either between circuit boards at short distances or between components within a rotating mechanism. This provides a compact and cost-effective solution that ensures stable data communication.
In traditional systems, slip rings are often used to transmit and receive electrical signals between rotating and stationary components to prevent cable tangling. However, with contact slip rings, the rotating brush and stationary metal ring gradually wear down, degrading signal quality and requiring regular maintenance. Noise from vibration and friction also contributes to a gradual deterioration of signal quality. Our new optical transceiver overcomes these challenges by using contactless spatial light transmission, ensuring consistent, high-quality communication.
The P16548-01AT features a vertical cavity surface emission laser (VCSEL) for light emission, combined with a temperature-compensated VCSEL controller, enabling
stable communication across a wide operating temperature range. It also includes a high-speed photodiode for light reception and a signal processing integrated circuit that maximizes the photodiode's performance characteristics, allowing for high-speed operation.
Leveraging our extensive experience developing optical devices and transceivers for fiber optic communication in automotive and industrial applications, we have applied our expertise to create this innovative solution. Our opto-semiconductor assembly and mounting technologies, combined with efficient manufacturing processes, allow us to offer this optical transceiver at a competitive price while maintaining excellent signal quality.
When installed in rotating systems such as robotic arms and omnidirectional cameras, the P16548-01AT ensures high signal quality by eliminating the limitations of traditional slip rings.
This optical transceiver also supports lead-free reflow soldering, where circuit boards are exposed to high temperatures up to 260°C.
We will expand this range of optical transceivers to meet growing market demand.
