MM connections
On MM connectors which are used almost exclusively in
inhouse applications, reflections have no great influence on
transmission quality. For this reason, MM connectors polishing
are offered only with PC-MM.
Optical fiber cables with connectors
KRONE makes to order cable connections for single mode (SM) and multimode applications (MM) with
optical connectors from our production and from other internationally leading manufacturers. Our range
consists of a great variety of cable versions and lengths and connector types. All cables are halogen free and
according to IEC 332-3C and IEC 332-1.
SM connections
The SM connector ferrules are offered with different types of polishing. Losses and reflections which can
occur in the connection depend to a large degree on the form and the surface quality of the ferrule face.
This in turn has a decisive influence on the signal transmission quality, especially in the case of high-rate
digital as well as analogue transmission.
The following ferrule polishing types are characterised:
■ PC polishing (Physical Contact) :
The convex form of the end surfaces ensures that there is no gap between the fiber ends and thus hardly
any reflection. The ferrule end surfaces are pressed against each other, when connected inside the adapter,
