PCF - Polymer Cladded Fibers

Stabil & Simple: Polymer cladded fibers (PCF) have been on the market for many
years, standing out by being very robust and easy to assemble.
PCF consists of a glass core with polymer cladding.

Responsibility: What is especially important here is good adhesion of the cladding material to the glass core, which does not go without saying because of the different expansion coefficients especially at high temperatures.

Absorption: It is also why there are a vast number of different abbreviations
for PCF such as PCS, HCS and HPCF. LEONI uses a fiber with NA = 037,
which shows especially low attenuation at 650 and 850 nm,
as its standard PCF. The low attenuation makes it possbile to bridge
distances of up to 500 m in systems designed for POF with 650 nm
and distances of up to 4 km in systems with 850 nm.

Modendispersion: The bandwidth of optical fibers with step-index profile such
as standard PCF is drastically restricted by the modal dispersion.
The use of gradient-index fibers is the best solution to this problem.

Extream & Fast: The cleavable multimode fiber with polymer cladding, ETFE buffer
and gradient-index core is the ideal solution for communication
applications that require high bandwidths in harsh industrial
environments. The adapted PCF fiber design has a positive influence
on the fiber properties in terms of service life, mechanical resilience
as well as higher moisture and temperature resistance in comparison
with standard multimode glass fibers with 62.5 μm core.
