- Data links and LANs
Overview
This series of high speed InGaAs photodiodes is designed for use in OEM fiber-optic communications systems and high-speed receiver applications including trunk line, LAN, fiber-in-the-loop and data communications. Ceramic sub- mount packages are available for easy integration into high speed SONET, FDDI, data link receiver modules, or as back facet power monitors in laser diode modules.
Available in hermetic TO-18 packages, in connectorized receptacle packages with industry standard FC or SC connectors, or in fibered TO- 18 package, these photodiodes are designed to function with either single or multimode fibers. Receptacle packages use a ball-lens TO-18 package to maximize coupling efficiency. All devices are planar passivated and feature proven, high reliability mounting and contacting.
Recognizing that different applications have different performance requirements, Excelitas offers a wide range of customization of these photodiodes to meet your design challenges. Responsivity and noise screening, custom device testing and packaging are among many of the application-specific solutions available
