Description
This Photodetector offers high linearity, low
capacitance and high responsivity. It is ideal for low
distortion applications such as CATV and Analog
Video. The device is packaged in a hermetically
sealed TO-46 package with antireflective coating for
optimum performance. A variety of assemblies
including pig-tail are available upon request.

Application Guidelines
ESD Handling
The PIN is sensitive to electrostatic discharges. When handling the device, precautions for ESD sensitive devices
should be taken. These precautions include use of ESD protected work area with wrist straps, controlled work
benches, floors etc.
Alignment Guidelines
In order to reach the specified intermodulation performance it is very important that the PIN diode is properly
aligned to the fibre. Thus active alignment is necessary. We recommend following procedure:
1. Position the top of the TO-46 lens 1.0 mm from the fibre end in axial direction. This correspond to a z-axial dis-
placement of 1.67 mm as shown in figure 2.
2. Align the TO-46 lens to the fibre in radial direction for maximum photo current.
3. Lock the position of the lens to the fibre.
