Optical Modules for General-Purpose Use
Application circuits
Receiving module with analog output for an optical flux monitor (TORX198 and TODX298)
There are two series in the TOSLINK family which are designed or
general-purpose use. One is the TOSLINK 170 Series which was the
first generation of TOSLINK. The other is the TOSLINK 190 Series,
which is part of the new generation. The main technical features of
modules for general-purpose use in the TOSLINK 190 Series are as
follows:
Data transmission rate:Up to 6 Mb/s or 8 Mb/s.
Transmission distance:Up to 1000 m with PCF.
Up to 40 m with APF.
Wider dynamic range: 6 dB wider than the
TOSLINK 170 Series.
Constant external resistor value irrespective of transmission
distance.
There are two connector types, the F05 (simplex) and F07 (duplex),
which are available for both the TOSLINK 170 and 190 Series devices.
Application circuits for the TOTX197 and TORX196, a pair of transmitting and
receiving modules for general-purpose use, are shown in the figure on the
right. For the TOTX197 transmission module, an external resistor is required to
supply current to the LED.
For the TORX196 receiving module, a noise filter must be placed on the power
line. The module case is made of conductive resin in order to have a shielding
effect against noise. All case pins must be securely grounded.
There are also duplex modules in the general-purpose TOSLINK series devices,
but application circuits for these are generally the same as for simplex modules.
Interfaces in these modules are all at the transistor-transistor logic (TTL) level;
hence it is easy to connect them with other circuits.
The general-purpose modules described above provide digital output. In
addition there is also one receiving module (TORX198) with an analog output
for amplifier.
The analog output voltage (output voltage of the amplifier in the receiving
circuit) depends on the optical power input into the receiving module.
Hence, it is possible to measure optical flux without an optical power meter,
by monitoring this analog output terminal.
When an optical flux-monitoring function is not required, this receiving module
is used for digital data transmission, like the other TOSLINK receiving
modules. In this case this analog output pin should be kept open.
There is also the optical module product having flux-monitoring functions
such the duplex type TODX298 (for PCF cables).
