| InGaAs-PIN/Preamp Receiver FEATURES * * * * Data rate up to 2.5Gb/s -23dBm typ. sensitivity 30m active area PIN chip with GaAs pre-amplifier Small co-axial package with multi-mode fiber FRM3Z231KT/LT KT APPLICATIONS * High bit rate short haul optical transmission systems operating at 2.5Gb/s DESCRIPTION These PIN preamplifiers use an InGaAs PIN chip with GaAs 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 multi-mode fiber by Nd: YAG welding. The detector preamplifier is DC coupled and has a low electrical output when the PIN is illuminated. These devices are in compliance with ITU-T Recommendations and meet Bellcore Requirements.
