Commissioning/application notes
maximum operating temperature of standard POF is approximately 60 °C and has a refraction profile with
step index (SI-POF). The refractive index of the core material is around 1.49 and that of the sheath around
1.41. The difference determines the numerical aperture (NA) and thus the maximum propagation angle. With
a difference of 5% this angle is about 20 degrees in relation to the fiber axis, which leads to a reduction in
the bandwidth.
Due to the simple and almost universally applicable connection techniques compared to glass fibers, POFs
are used in particular for short transmission distances, such as inside rooms, technical equipment,
mechanical systems or cars.
POFs have an attenuation of about 140 dB/km at a wavelength of 650 Nm, so that a maximum data
transmission distance of 50 m can be achieved when used with the EK1541.
Insertion of additional connectors in the route increases the signal attenuation. For each additional plug
connector, the maximum permitted distances typically reduces by 6.5 m.
5.2.2.2 Application with EK1541
Recommended plug connectors and POF cables
For the connection of the EK1541 it is recommended to use the connector set ZS1090-0008
[} 62] (Versatile Link Duplex connectors) in conjunction with a duplex polymer fiber with
Note
an outside diameter of 2 x 2.2 mm (Z1190), which are available from Beckhoff.
Installation notes
• permissible bending radius (in general r ≥ 25 mm, refer to the manufacturer's data!)
• permitted tensile strength
Note
• sensitivity of the exposed contact ends
Connecting and releasing the POF cable at the coupler
To connect the cable, insert the plug (available as an accessory in the plug set ZS1090-0008) into the
connection opening until it audibly latches.
Fig. 41: Latching lug with release catch on the POF duplex plug
To release the connector activate the release device with the latching lug. This can be found on the right-
hand side of the connector (see figure).
Risk of damage to the cable!
To release the cable, press the release catch on the plug and pull the plug at the same time
– never pull by the POF cable alone!
