Online-Catalog: data transmission
The setup of a POF based data transmission network
requires an optical transceiver at each POF cable endface. It
transforms electrical data to optical data and vice versa. The
transceiver unit may be:
- an OEM transceiver that is integrated to the electronic
network module and uses a non standard interface defined by the
customer,
- a standard transceiver module (e.g. comprising 1x9 or 2x5 pin interface) that is irremovable soldered to the network module, or
- a pluggable transceiver (e.g. according the SFP standard).
Each approach has pros and cons:
- OEM defined integrated
transceivers are very low cost in volume and are preferred in
universally used, large volume standard network modules. POF media
converters that are a volume product with non varying functionality are an example.
- Transceivers that are designed
for integration by soldering via a standard interface allow the module
manufacturer to use a standard interface on his PCB for different types
of optical tranceivers. The PCB can be used for different network
module functionalities, e.g. for glass fiber and POF applications as
well. The final user cannot change the transceiver.
- The customer
advantage of the more and more wide-spread, pluggable SFP transceivers
is the option to use an SFP suitable network module with the exact
number and the excat type of transceiver he wants. The customer is not
forced to pay for additional transceivers he doesn't want to use. There
are no "wrong" types of transceivers that are non-exchangable
integrated to the network module. The network manufacturer advantage is
obvious, too: he can offer one type of network module that can be
flexibly adapted to very different functionalities simply by changing
the type of SFP transceiver. Pluggable transceivers will be the future
solution in optical networking.
Due to the world wide tendency
to pluggable tranceivers DieMount decided in 2007 to stop the
development and fabrication of solderable transceivers with standard
interface. If you are interested in an OEM product with solderable
standard interface, please contact us.
At present we offer the following product groups for the data transmission via POF:
