Hamamatsu adds 1.25Gbps spatial light transceiver
Hamamatsu Photonics has announced a new optical transceiver for spatial light transmission, enabling cable-free optical data communication over spatial distances up to 100 mm.
The P16548-01AT device, which supports full-duplex bidirectional communication up to 1.25 gigabits per second, features a VCSEL for light emission, combined with a VCSEL driver capable of temperature compensation, for stable communication over a wide operating temperature range.
It also includes a high-speed photodiode for light reception and a signal processing IC that maximises the photodiode performance characteristics, enabling high-speed operation.
The P16548-01AT is said to maintain consistent performance, even during communication between a stationary object and those rotating 360 degrees, such as robotic arms and omni-directional cameras. This is achieved by eliminating the limitations of traditional slip rings, according to Hamamatsu.
The optical transceiver supports lead-free reflow solder mounting where circuit boards are exposed to high temperatures up to 260°C.
