FRM5W621LT

InGaAs-APD/Preamp Receiver FEATURES Data rate up to 622Mb/s High Responsibility: typ. 0.85A/W at 1,550nm 30µm active area APD chip with GaAs pre-amplifier High temperature operation up to +85°C Small co-axial package with single mode fiber FRM5W621KT/LT KT APPLICATIONS Medium bit rate long haul optical transmission systems at STM-4 (OC-12) DESCRIPTION These APD preamplifiers use an InGaAs APD 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 single-mode fiber by Nd: YAG welding. The detector preamplifier is DC coupled and has a low electrical output when the APD is illuminated.
