Request InfoVI Systems GmbHVI Systems GmbH has released the A40-300C integrated circuit for optical data transmission applications. Its vertical-cavity surface-emitting laser (VCSEL) driver chip, with serial data rates of 25 and 40 Gb/s over a 50/125-μm multimode fiber, is designed for high-speed optical transceivers. The integrated circuit is suitable for use in conventional VCSEL products and in the proprietary EOM DBR (Electro-Optical Modulated Distributed Bragg Reflector) VCSEL design. Measuring 800 x 600 μm, it can be used universally for voltage or current modulation.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2023 IssueSilica Core Optical FibersThe Optran® Plus UV and Optran Plus WF pure fused silica core fibers from Armadillo SIA feature high numerical aperture and spectral transmission from 190 to 2400 nm with low optical losses. ...Photonics Spectra December 2023 IssuePluggable Optical Channel MonitorThe QSFP OCM (optical channel monitor) from PhotonPath, in collaboration with Jabil, is a pluggable optical channel monitor on a quad small form factor pluggable (QSFP) form factor created as a...Photonics.com 4/2/2024Optical Transport SolutionsThe optical transport solutions from Nokia are meant for optical transport, IP routing, and PON applications and include coherent optical transceivers, a photonic engine, and a multihaul transceiver....Photonics.com 4/1/2024Compact ROADMThe DCP-R-34D-CS from Smartoptics is a compact reconfigurable optical add/drop multiplexer (ROADM) for larger fiber optic networks.
