Technical Data
Thermal Characteristics
The thermal behaviour of PAROLI modules (transmitter and receiver) depends on the
operating conditions for different applications.
The following table gives a guideline for system designers.
The thermal resistance R_th ( R_th

can be used for calculating the module case temperature under different operating
conditions and is displayed for two different module options:
a) Baseplate module without heat sink.
b) Baseplate module with customer designed heat sink
(e.g. height = 9 mm, length = 41 mm, width = 18 mm, no. of cooling fins = 9).

Link Length
The link length calculations are based on the most conservative assumption of PAROLI
modules working on their worst case specification limits. Multimode fibers of different
types (modal bandwidth at 850 nm) are shown. The stated link length is valid under all
specified operating conditions and includes 2 dB of additional connector loss.
