FEATURES
KT
• Data rate up to 2.5Gb/s
• -32dBm typ. sensitivity
• 30µm active area APD
chip with GaAs preamplifier
• Small co-axial package
with single mode fiber
APPLICATIONS
• High bit rate long haul optical transmission systems operating
at 2.5Gb/s
LT
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.
