FRM5W231LT Datasheet | Eudyna Devices

FEATURES - Data rate up to 2.5Gb/s - -32d Bm typ. sensitivity - 30µm active area APD chip with Ga As preamplifier - Small co-axial package with single mode fiber FRM5W231KT/LT APPLICATIONS - High bit rate long haul optical transmission systems operating at 2.5Gb/s DESCRIPTION These APD preamplifiers use an In Ga As APD chip with Ga As IC preamplifier. The KT package is designed for a horizontal PC board mount. The LT package is secured by a vertical flange. Each package is connected with single mode fiber by Nd: YAG welding. The detector preamplifier is DC coupled and has a low electrical output when the APD is illuminated. ..
