Unlike glass fibres, whose core is made of quartz glass, the core of a POF consists of polymer such as polymethyl methacrylate or polycarbonate. The material typically used for the jacket is fluorinated polymer. A significant difference between the POF and glass fibre is the far larger core diameter of the POF. A relatively large difference in the refraction index leads to a large acceptance angle, which nevertheless provides an acceptable bending radius.
First of all, it should be noted that the class cannot be compared with the category. The class refers to the cabling route, whereas the category applies to components. The Duplex Fibre 2.2 DATALIGHT belongs to class D. Class D means up to 100 MHz, suited for data rates of up to 1 Gbps.
The Duplex Fibre 2.2 DATALIGHT is composed of the polymer fibre, the reflection layer and the jacketing. The PMMA polymer fibre (Plexiglas) is 1 mm thick and, together with the jacket, features an outside diameter of 2.2 mm.
The POF cable is manufactured without UV stabiliser and therefore not suitable for outdoor use without additional protection.
Based on experience, the cutter can be used up to 20 times without deteriorating data transmission. We recommend that you do not use it anymore after deformation of the blade becomes visible, since this can lead to higher attenuation.
Yes. The Duplex Fibre DATALIGHT is insensitive to electromagnetic fields. Due to this, power lines can also be installed in the electrical conduit parallel to the data line.
We recommend that you use 65 mm deep connection sockets.
All devices bearing the DATALIGHT logo are compatible with each other. This is also true for devices with different speed rates (100 Mbps or 1 Gbps). However, the maximum data rate decreases during operation of, e.g. a 100 Mbps access point with a 1 Gbps switch to the maximum data rate of the slowest device.
Prior to connecting the fibre to the access point and the switch : Use a pocket torch to light into the end of the fibre – if light can be seen on the other end of the fibre, the fibre functions flawlessly. As soon as the fibre has been connected to the access point and the switch, green LEDs on the components indicate that they function correctly. Additionally, there are level measuring devices to calibrate the route.
No! When connecting to electronic components and when attaching two fibre ends to each other, the fibre must be used with a jacket. It protects the fibre from damage and prevents light emission. A clean cut prior to connection ensures very low attenuation.
