Albis Optoelectronics announced the availability of the PX512, a 4.25 Gb/s receiver optical subassembly for 850 nm optical communications. This high-sensitivity, 5 pin low-cost coaxial module comes with two different pin layouts, provides a photocurrent monitor signal and acts as a basic building block for multimode 4G Fiber Channel applications. The product converts optical power into an electrical signal at data rates from 155 Mb/s up to 4.25 Gb/s and utilizes a PIN/TIA integrated in a TO-46 package aligned to a precision plastic LC port for usage with 50/125μm and 62.5/125μm multimode fiber.
